Best Weather States in America: All 50 Ranked

California takes the top spot. Alaska finishes last. I scored every state on 4 NOAA climate metrics — sunshine hours, temperature comfort, humidity, and rainy days — to build a ranking that actually uses data instead of vibes.

How We Scored Each State

Most "best weather" lists are opinion pieces. This one isn't. I pulled four metrics from NOAA's 1991-2020 Climate Normals and our own database of 139 million daily weather observations, then scored each state 0-100 across all four:

Sunshine hours/year
Total annual hours of sunshine from NOAA CCD. Arizona leads at 3,806; Alaska trails at 1,730.
Comfort days (60-85°F)
Days where the high temperature falls between 60-85°F — the range most people find pleasant without AC or heat.
Low humidity
Average annual relative humidity inverted (lower = better). Nevada wins at 38.3%; Florida loses at 74.5%.
Few rainy days
Annual days with measurable precipitation inverted (fewer = better). Nevada wins at 24; Alaska trails at 113.

Each metric is weighted equally (25% each). The composite score is normalized to 0-100. This favors states with balanced weather — lots of sun, moderate temperatures, low humidity, and few rainy days. A state can score high on sunshine but lose points for extreme heat (Arizona) or humidity (Florida).

What the Data Actually Shows

The top 5 won't surprise anyone: California, Arizona, Hawaii, Nevada, New Mexico. They're all in the Sun Belt or Pacific. But the interesting stories are in the middle.

Florida is overrated. The "Sunshine State" ranks just #8 and doesn't even crack the top 10 in sunshine hours (#10 nationally). What kills Florida's score is humidity (74.5%, highest in the lower 48) and 82 rainy days per year. June through September feels like breathing through a wet towel. Florida gets by on 188 comfort-range days — second only to Hawaii — but anyone who's spent August in Miami knows those "75°F" mornings don't feel like 75.

Colorado is underrated. Denver gets 300 days of sunshine — more than Miami or San Diego. At 5,280 feet, the dry air means 90°F feels like 82°F. Winters on the Front Range are mild (40s-50s with snow that melts by afternoon). The catch is wildfire smoke from Western fires increasingly degrading August and September air quality. But for 10 months of the year, Colorado's climate is outstanding.

Oregon is two states. Portland gets 144 rainy days; Bend gets 300 days of sunshine. The Cascades create one of the sharpest climate divides in the country. If you only measured eastern Oregon, it would rank top 15. Western Oregon drags the statewide average down significantly.

The "misery belt" is real. A band of states from Maine through the Great Lakes (Maine, Vermont, New Hampshire, Michigan, Wisconsin) clusters at the bottom. They combine limited sunshine, long winters, high humidity and frequent rain — hitting all four negative metrics simultaneously. The only saving grace: their summers (June-August) are genuinely pleasant.


2026 Context

The developing Super El Niño is reshuffling weather patterns across the country. Southern California and the Desert Southwest are getting drier than normal while the Gulf Coast and Southeast are seeing above-average rainfall. By summer 2026, NOAA projects elevated heat across the southern tier and potential drought intensification in the West — which means the top-ranked states could temporarily feel less pleasant than their normals suggest.

Sun: 3,254h
Comfort: 183d
Humid: 58.2%
Rain: 36d

The most diverse climate in the country — San Diego averages 266 sunny days while San Francisco gets fog 108 days a year. Southern California's combination of sunshine, mild temps, and low humidity is nearly unbeatable. Drawback: wildfire smoke season (Aug-Oct) is getting worse.

A+84
Sun: 3,806h
Comfort: 145d
Humid: 38.5%
Rain: 33d

The sunniest state — Yuma sees 90% of all possible sunshine. Phoenix gets 299 days above 60°F. The catch: summer is genuinely dangerous. Phoenix averaged 31 consecutive days above 110°F in 2023, and monsoon season (July-Sept) brings violent dust storms and flash floods.

A82
Sun: 2,835h
Comfort: 292d
Humid: 63.6%
Rain: 100d

The highest average temperature (70.2°F) and most "comfortable" days of any state. Trade winds keep humidity tolerable despite being surrounded by ocean. Downside: windward sides get drenched (Hilo: 126" of rain/year), and Maui/Big Island vog from Kilauea can irritate lungs.

A78
Sun: 3,466h
Comfort: 128d
Humid: 38.3%
Rain: 24d

The driest state in the US — Las Vegas averages only 4.2" of rain per year. Fewest rainy days of any state (24). Desert heat is brutal in summer (115°F+ in Vegas), but the dry air means 95°F feels significantly less oppressive than 85°F in Florida. Reno at 4,500' is much cooler.

Sun: 3,593h
Comfort: 136d
Humid: 45.9%
Rain: 42d

Second-sunniest state (3,593 sunshine hours). Albuquerque at 5,300' gets 310 days of sunshine without the oven-like heat of Phoenix. Low humidity makes everything feel cooler. Santa Fe (7,000') is cooler still. Summer monsoons bring brief afternoon thunderstorms July-August.

Sun: 3,226h
Comfort: 110d
Humid: 52.8%
Rain: 48d

Denver gets 300 days of sunshine — more than Miami or San Diego. Dry air, mild winters in the Front Range (40s-50s), and cool mountain summers. The 5,280' elevation means UV is intense. Wildfire smoke from Western fires increasingly degrades August-September air quality.

A-72
Sun: 3,050h
Comfort: 158d
Humid: 64.4%
Rain: 57d

Texas is really 4 states weather-wise. West Texas (El Paso) is sunny and dry. Hill Country (Austin, San Antonio) gets the best mix. Houston is a steam bath June-September (75% humidity). The Gulf Coast gets hammered by hurricanes. Statewide, the sunshine and warm temps score well.

A-71
Sun: 2,926h
Comfort: 188d
Humid: 74.5%
Rain: 82d

The "Sunshine State" is actually only #10 in sunshine hours. Its real strength: 188 comfort-range days, second only to Hawaii. The weakness: Florida is the most humid state in the lower 48 (74.5%), and 82 rainy days drag it down. Summer feels like breathing through a wet towel.

A-70
Sun: 3,130h
Comfort: 105d
Humid: 51.6%
Rain: 40d

Desert sunshine in the south, mountain weather in the north. St. George (2,900') has the best climate in the state — mild winters, 300 days of sun. Salt Lake gets inversions (trapped smog) in winter. The national parks (Zion, Bryce, Arches) are beautiful but baking hot June-August.

A-69
Sun: 2,821h
Comfort: 161d
Humid: 67.1%
Rain: 76d

Atlanta hits the sweet spot: warm enough for year-round outdoor living, cooler than coastal Georgia in summer thanks to 1,000' elevation. Spring (March-May) is spectacular. Humidity climbs in July-August. Mountains in the north stay 10-15°F cooler. Hurricane remnants bring occasional flooding.

Sun: 2,787h
Comfort: 156d
Humid: 68.2%
Rain: 73d

Charleston has some of the most pleasant springs and falls in America. 156 comfort-range days. The coast gets more hurricanes than you think (Hugo 1989, Irma 2017). Summer humidity is rough — Myrtle Beach regularly hits heat index 110°F+.

Sun: 2,708h
Comfort: 147d
Humid: 68.5%
Rain: 76d

Mountains, piedmont, and coast give you three climates. Asheville (2,134') has the best year-round weather — mild summers, moderate winters, low humidity. Charlotte is comfortable 8 months/year. The Outer Banks are wind-blasted but beautiful. Raleigh-Durham hits the middle ground.

B+66
Sun: 2,950h
Comfort: 134d
Humid: 62.5%
Rain: 57d

More sunshine than most people expect (2,950 hours). Falls and springs are beautiful. The problem: Oklahoma sits in Tornado Alley. The state averages 56 tornadoes per year — more per square mile than anywhere else. Summer hits 100°F+ regularly. Ice storms shut things down in winter.

B+65
Sun: 2,908h
Comfort: 119d
Humid: 63.1%
Rain: 55d

Plenty of sunshine and relatively low rainy days. Springs and falls are pleasant. Summer heat and winter blizzards are the extremes. Tornado risk is real but concentrated in spring. Wichita has a surprisingly comfortable overall climate profile.

B+64
Sun: 2,296h
Comfort: 90d
Humid: 68.3%
Rain: 78d

The great Oregon divide: east of the Cascades (Bend) gets 300 sunny days; Portland gets 144 rainy days. Portland's summers (July-Sept) are spectacular — 80s, dry, long evenings. The other 9 months are gray and drizzly. Wildfire smoke from California increasingly ruins August.

B63
Sun: 2,691h
Comfort: 168d
Humid: 74%
Rain: 90d

Lots of warm days but punishing humidity. New Orleans averages 90 rainy days/year and 74% humidity. Spring (March-May) is genuinely lovely. Summer is miserable. Hurricane season is a real threat — Katrina, Laura, Ida hit within 16 years. Mild winters partially redeem it.

Sun: 2,642h
Comfort: 156d
Humid: 73.6%
Rain: 87d

Similar climate to Louisiana — warm, humid, and rainy. 156 comfort days is respectable, but 87 rainy days and persistent humidity drop the score. Tornadoes are a spring concern. Winter is short and mild. Summers are long and oppressive.

B62
Sun: 2,580h
Comfort: 141d
Humid: 68.7%
Rain: 80d

Nashville gets 207 sunny days, which surprises most people. Four distinct seasons with a mild-ish winter. Great Smoky Mountains are beautiful but among the foggiest places in the US. Summer humidity is significant. Tornado risk is rising — Nashville took direct hits in 2020 and 2023.

B61
Sun: 2,595h
Comfort: 152d
Humid: 70.2%
Rain: 83d

Long growing season, warm temperatures, but too much rain (83 days/year) and humidity to rank higher. Spring is tornado season — the April 2011 super outbreak killed 238 in Alabama alone. Gulf Coast gets hurricane threats. Birmingham's elevation (600') provides slight relief from summer heat.

B61
Sun: 2,528h
Comfort: 131d
Humid: 67.3%
Rain: 75d

Northern Virginia is basically the Mid-Atlantic — hot summers, cold-ish winters. The Shenandoah Valley has beautiful seasons. Virginia Beach is pleasant March-November. Fall foliage (Oct) along Skyline Drive rivals New England. Hurricane remnants occasionally bring inland flooding.

B60
Sun: 2,609h
Comfort: 140d
Humid: 68.4%
Rain: 77d

Springs and falls are lovely — the Ozarks in October are underrated. Summer heat is comparable to Tennessee. Tornado Alley extends into western Arkansas. Hot Springs has a unique microclimate. Humidity is the main drawback, especially June-August.

B59
Sun: 2,480h
Comfort: 126d
Humid: 66.5%
Rain: 72d

Mild Mid-Atlantic climate with real four seasons. Summers are warm and humid but brief. Rehoboth Beach is pleasant June-September. Proximity to the ocean moderates temperatures in both directions. Nothing extreme — which is the appeal.

B59
Sun: 2,518h
Comfort: 124d
Humid: 66.8%
Rain: 74d

Very similar to Delaware. Baltimore's summers are sticky (Chesapeake humidity). Western Maryland mountains are cooler and drier. The Eastern Shore has pleasant breezes. Spring cherry blossom season (late March) is peak DC/Maryland weather.

B-58
Sun: 2,753h
Comfort: 106d
Humid: 63.2%
Rain: 54d

More sunshine than you'd expect (2,753 hours). Omaha has genuinely pleasant Mays and Septembers. Winters are harsh (January avg 22°F in Omaha). Tornado risk in spring. Low humidity is a plus. Not flashy, but the dry continental climate has fewer miserable days than the Southeast.

B-58
Sun: 2,614h
Comfort: 125d
Humid: 66.2%
Rain: 69d

St. Louis and Kansas City both get four real seasons. Falls are beautiful. Summer humidity rivals Houston at times. Tornado risk is significant — the Tri-State tornado (1925) killed 695 and remains the deadliest in US history. Ice storms can shut down the state in winter.

B-57
Sun: 2,483h
Comfort: 132d
Humid: 69.1%
Rain: 79d

Horse country has beautiful springs and falls. Lexington is cooler than Louisville. Summer humidity is tough but not as bad as the Gulf states. Winter brings occasional ice storms that are worse than snow. Kentucky Derby day (first Saturday in May) usually has perfect weather.

B-56
Sun: 2,650h
Comfort: 72d
Humid: 55.4%
Rain: 50d

Eastern Montana is sunny and dry — Helena gets more sunshine than LA. Western Montana (Glacier NP area) is cloudier and wetter. Winters are cold but the dry air makes 20°F feel less brutal than 35°F in Ohio. Summer days are long and gorgeous (80°F, sunset at 9:30 PM). Wildfire smoke is the new season.

B-56
Sun: 2,864h
Comfort: 67d
Humid: 52.1%
Rain: 48d

Tons of sunshine (2,864 hours) and the driest state east of Nevada. The catch: wind. Wyoming is the windiest state in the continental US — Cheyenne averages 12.9 mph year-round. Winters are genuinely cold. Summer in the high country (Yellowstone, Tetons) is spectacular but brief.

Sun: 2,745h
Comfort: 82d
Humid: 62.4%
Rain: 50d

Western South Dakota (Rapid City, Black Hills) has mild summers and dry air. Eastern South Dakota is more humid and tornado-prone. Sioux Falls winters are long and cold. The Badlands in September-October are spectacular. More sunshine than most Midwestern states.

C+54
Sun: 2,564h
Comfort: 78d
Humid: 55.8%
Rain: 52d

Boise has 206 sunny days and low humidity — it's genuinely underrated. Southern Idaho (Snake River Plain) is high desert. Northern Idaho (Coeur d'Alene) is Pacific Northwest with more snow. Wildfire smoke from surrounding states is a growing summer issue.

#31Iowa
C+54
Sun: 2,582h
Comfort: 96d
Humid: 66.9%
Rain: 61d

Humid continental with real extremes — summer highs in the 90s, winter lows below zero. Des Moines gets 96 comfort days, mostly in May-June and September. Tornado risk is concentrated in spring. Derechos (August 2020) are the underappreciated threat.

Sun: 2,636h
Comfort: 64d
Humid: 64.3%
Rain: 54d

Cold but sunny. Fargo gets more sunshine hours than Pittsburgh or Portland. The problem: winter dominates. January average in Bismarck is 10°F. But summer days (June-August) are long, dry, and pleasant at 80-85°F. Lowest humidity of any Great Plains state.

C+53
Sun: 2,440h

Chicago's lakefront creates its own microclimate — 5-10°F cooler in summer (great) and windier in winter (miserable). Southern Illinois has a warmer, more Southern climate. Downstate gets more tornadoes than most people realize. The 1995 Chicago heat wave killed 739 people.

Sun: 2,170h
Comfort: 70d
Humid: 69.5%
Rain: 86d

Seattle gets 152 rainy days — but summer (July-Sept) is one of the best climates in America. 75°F, low humidity, 16-hour days. Eastern Washington (Spokane) is sunnier and drier. Olympic Peninsula gets 140-170" of rain/year. Wildfire smoke increasingly ruins August.

C51
Sun: 2,458h
Comfort: 74d
Humid: 66.7%
Rain: 62d

International Falls earned the title "Icebox of the Nation" (-40°F is not unusual). Minneapolis winters average 17°F in January. But Minnesota summers are beautiful — 80°F, long days, 10,000 lakes. The May 2026 super outbreak produced the first Minnesota EF5 in state history.

Sun: 2,467h
Comfort: 118d
Humid: 66%
Rain: 73d

Mid-Atlantic standard: humid summers, cold winters, pleasant spring/fall windows. The Shore is 5-10°F cooler than inland in summer. Northern NNJ gets more snow. Climate change is making NJ warmer — Ida (2021) brought unprecedented inland flooding that killed 30.

#38Ohio

Rain: 80d

Mountain weather: cooler summers than surrounding states, but cloudier and wetter. Snowshoe Mountain gets 180" of snow at 4,848'. The New River Gorge in fall is stunning. Fog is frequent in valleys — Charleston averages 90 foggy mornings. Flooding is a recurring problem.

Sun: 2,370h
Comfort: 104d
Humid: 65.5%
Rain: 75d

Narragansett Bay moderates temperatures — Newport rarely hits 90°F in summer or 10°F in winter. But the ocean influence also brings fog, nor'easters, and block storms. The state is small enough that ocean weather affects every corner. Pleasant but raw.

D42
Sun: 2,264h
Comfort: 72d
Humid: 67.8%
Rain: 77d

Acadia in September-October is magical, but the rest of the year is cold, foggy, and short on daylight. Portland averages 72 comfort days — barely 2 months of pleasant weather. The coast gets 61" of snow and dense fog (11 days in June alone). Interior Maine hits -30°F in deep winter.

Sun: 2,302h
Comfort: 78d
Humid: 66.5%

Fall foliage is superb. Winters are long and snowy (64" average in Concord). A place for people who like their weather dramatic.

D40
Sun: 2,218h
Comfort: 73d
Humid: 68%
Rain: 79d

Green Mountains, gorgeous falls, brutal winters. Burlington averages 74" of snow and only 73 comfort days. Mud season (March-April) makes many dirt roads impassable. Summer is brief but glorious — Lake Champlain at 78°F in July. The trade-off: 5 months of cold for 2 months of perfection.

F30
Sun: 1,730h

The anti-California. Anchorage averages 28 comfort days per year. Barrow goes 65 days without seeing the sun in winter. Juneau gets 222 rainy days and 86" of snow. Interior Alaska (Fairbanks) swings from -40°F in January to 80°F in June. But those summer solstice days at 19+ hours of light are unlike anything else.


5 Biggest Surprises in the Data

1. Florida has fewer sunny days than Montana

Florida averages 101 sunny days; Montana gets 116. Florida's afternoon thunderstorms from May through September eat into its sunshine totals significantly. The "Sunshine State" nickname comes from marketing, not meteorology.

2. Boise, Idaho has better weather than Portland, Oregon

Idaho (#30) outranks Washington (#35) because Boise sits in the high desert at 2,700 feet. It gets 206 sunny days, low humidity, and only 52 rainy days — while Seattle gets 86 rainy days and 152 overcast days.

3. Oklahoma gets more sunshine than Virginia

Despite the tornado risk, Oklahoma (#13) ranks higher than Virginia (#20). Oklahoma's 2,950 sunshine hours and 134 comfort days outperform Virginia's more moderate but cloudier climate. The data doesn't penalize for extreme weather events — only for average conditions.

4. Alaska isn't even close to #49

At 30 points, Alaska scores 10 points below Vermont (#49, 40 points). Only 28 comfort days per year — fewer than any other state by a margin of 36 days. Alaska isn't just cold; it's also rainy (113 days), humid (72.5%), and dark (Barrow: 65 days without sun in winter).

5. Nebraska (#24) beats Tennessee (#18) on paper

They score within 4 points of each other, but Nebraska gets 2,753 sunshine hours to Tennessee's 2,580, and only 54 rainy days vs. 80. Tennessee wins on comfort days (141 vs 106) and average temperature. It depends on what you value: dry sunshine or warm comfort.


What This Ranking Doesn't Capture

This scoring system measures average conditions. It doesn't penalize for extreme weather events like tornadoes, hurricanes, wildfires, or floods. Oklahoma ranks #13 despite being in Tornado Alley. Florida ranks #8 despite hurricane exposure. California ranks #1 despite worsening wildfire smoke seasons.

If you weighted extreme weather risk, the rankings would shift significantly. Oklahoma, Florida, and Texas would drop; Colorado, Oregon, and Idaho would rise. A state like North Carolina — which faces hurricanes, tornadoes, and ice storms — would fall further despite its pleasant averages.

Frequently Asked Questions

Which US state has the best weather year-round?

California ranks #1 overall using NOAA climate data. Southern California combines 3,254 sunshine hours per year, 183 days between 60-85°F, low humidity (58.2%), and only 36 rainy days. San Diego specifically has the best year-round climate of any major US city, with temperatures between 57-76°F in every month.

What is the sunniest state in America?

Arizona is the sunniest state with 3,806 sunshine hours per year and 193 sunny days. Yuma, Arizona holds the Guinness World Record as the sunniest city on Earth — sunshine during roughly 91% of all daylight hours. However, Arizona ranks #2 overall because extreme summer heat (Phoenix averaged 31 consecutive days above 110°F in 2023) reduces the number of comfortable days.

Which states have the most comfortable temperatures?

Hawaii leads with 292 days per year where highs fall between 60-85°F, thanks to trade wind-moderated oceanic temperatures. Florida is second with 188 comfort days, followed by California (183), Louisiana (168), and Georgia (161). Cold northern states have the fewest: Alaska (28), North Dakota (64), and Wyoming (67).

What is the least humid state?

Nevada is the least humid state at 38.3% average relative humidity, followed closely by Arizona (38.5%) and New Mexico (45.9%). All three are desert states where dry air makes warm temperatures feel significantly more comfortable. By contrast, Florida averages 74.5% humidity and Alaska 72.5%.

Does the state with the most sunshine have the best weather?

No. Arizona has the most sunshine hours (3,806) but ranks #2 because extreme summer heat dramatically reduces livable comfort days. California has fewer sunshine hours (3,254) but ranks #1 because its temperatures stay in the comfort range more often. Hawaii has even fewer sunshine hours (2,835) but ranks #3 because trade winds and oceanic moderation produce the most consistently pleasant temperatures in the country. Weather quality is about balance, not any single metric.


Data Sources & Methodology

Temperature, precipitation, and humidity averages from NOAA NCEI 1991-2020 Climate Normals. Sunshine hours from NOAA Comparative Climatic Data. Solar radiation data from the CDC's National Environmental Public Health Tracking Network. Comfort days calculated from our database of 139M+ daily NOAA observations (1970-present). State averages weighted by population-adjusted station coverage to prevent rural stations from skewing results. Scoring methodology: each metric normalized 0-100 within its range, then averaged with equal weighting.
