Climate
States With the Best Weather Year-Round
By Cal Hendricks · April 23, 2026
Most Americans live in states where they dread at least three months of the year. A handful of states offer genuinely mild temperatures in every season, and the differences between them come down to humidity, rain, and how much heat you can tolerate.
Most Americans tolerate their climate rather than enjoy it. Only a small cluster of states delivers comfortable temperatures in every month of the calendar year, and the gap between them is wider than most people expect.
What "Best Weather" Actually Means
Best weather is not the same as warmest weather. Florida averages 237 sunny days per year, but July in Miami hits a heat index above 105°F with humidity that makes outdoor activity genuinely dangerous. The most livable climates tend to stay in the 55°F to 85°F range across all twelve months, with low humidity and minimal extreme weather events.
For this ranking, we weighted four factors: average temperature range (penalizing extremes in both directions), humidity, annual sunshine hours, and severe weather frequency. That last factor is increasingly relevant. As of April 2026, FEMA's National Risk Index lists Louisiana, Florida, and the Gulf Coast as the highest-risk areas for climate-related disasters, including hurricanes, flooding, and heat emergencies.
The Top States for Year-Round Comfort
California sits at the top by almost every measure, specifically the coastal zone from San Diego to Santa Barbara. San Diego averages a high of 66°F in January and 76°F in August. Annual rainfall is 10 to 12 inches. The tradeoff is cost: California's state income tax tops out at 13.3%, the highest marginal rate in the country, and median home prices in San Diego County crossed $900,000 in early 2026. Weather is excellent. The financial picture is not. See our breakdown of Florida vs. California: The Tax Reality for the full comparison.
Hawaii is the only state that technically never freezes at sea level. Honolulu's average monthly temperature ranges from 73°F in February to 83°F in August. Trade winds keep humidity bearable on the windward coasts. The major drawbacks are cost of living (the highest in the nation), geographic isolation, and a state income tax rate of 11% on income above $200,000.
Arizona, specifically the Tucson and Scottsdale metro areas, offers 299 sunny days per year and dry heat rather than humid heat. Winters are genuinely mild: Phoenix averages 67°F highs in December. The problem is summer. Phoenix recorded 31 days above 115°F in the summer of 2025, a trend that has continued into 2026 and pushed summer outdoor livability below what the raw averages suggest.
South Carolina's coastal region, particularly around Charleston and Hilton Head, offers warm winters, mild springs, and a shorter brutal-summer window than states further south. Charleston averages 59°F in January and 91°F in August. Hurricane risk is real, but lower than Florida's Gulf Coast on historical frequency.
Florida makes every list and deserves to. But the weather case is strongest in the northern half of the state. Miami's summer heat index problem aside, cities like Sarasota and Naples offer genuine winter comfort, averaging 75°F highs from November through March. Florida also has no state income tax, which amplifies the appeal for retirees. Check out our Best States for Retirees to Avoid Taxes guide for the full picture.
Where Climate Change Is Reshaping the Rankings
The 30-year climate averages that most weather rankings rely on are increasingly misleading. The National Oceanic and Atmospheric Administration updated its climate normals baseline in 2021, and conditions have continued shifting since. States that looked attractive a decade ago, particularly in the Gulf Coast and Southwest, now carry measurably higher risks.
If you're making a 20-plus year housing decision, the Pacific Northwest and Upper Mountain West deserve more attention than they get. Bend, Oregon averages 158 sunny days and mild shoulder seasons, with none of the hurricane, tornado, or extreme-heat risk of the Sun Belt. Boise, Idaho offers 206 sunny days and four distinct but moderate seasons. Neither city shows up on most weather lists, but both are holding their climate quality better than their southern competitors.
The Weather-Tax Trade-Off
The dirty secret of the best-weather states is that the best ones tax heavily. California and Hawaii combine excellent climates with some of the highest income tax burdens in the country. Florida and Texas combine tolerable to good weather with zero state income tax, which is why both continue to attract net migration despite rising heat and storm risk.

Key Takeaways
- San Diego, California holds the most consistently mild temperatures in the continental U.S., ranging from 66°F to 76°F average highs, but carries a 13.3% top marginal income tax rate.
- Phoenix logs 299 sunny days per year but recorded 31 days above 115°F in summer 2025, making summer livability a serious concern for outdoor-oriented residents.
- Florida's no-income-tax advantage combined with mild winters makes it the strongest weather-plus-tax value on this list, particularly for retirees on fixed income.
