There isn’t one single best weather state in the US; the answer changes depending on whether you weight temperature, sunshine, humidity, or storm risk most heavily. That said, most independent rankings, including analysis based on NOAA climate data, put California at or near the top, with Hawaii, Arizona, and a handful of Southwestern states close behind. This guide breaks down why, and helps you figure out which state actually fits your own definition of good weather.
This is written for anyone comparing states for relocation, retirement, or long-term travel, not for someone planning a single vacation. If you mainly care about a two-week trip, monthly averages matter less than what’s happening that specific week, and a short-range forecast will serve you better than any annual ranking.
Key Takeaways
- California generally ranks first in broad “best weather” comparisons because it combines mild coastal temperatures, low humidity, and relatively few severe storms, not because it’s the warmest state overall.
- By raw average temperature, Florida and Hawaii actually rank higher than California, but heat and humidity aren’t the same as comfort, which is why methodology changes the winner.
- Arizona and New Mexico perform well in rankings that weight winter sunshine and low storm frequency heavily, even though summer heat there is extreme.
- “Best weather” always trades off against something: wildfire risk in California, hurricane exposure in Hawaii and the Gulf Coast, or summer heat in the desert Southwest.
- The right state depends on which discomfort you can tolerate least: heat, cold, humidity, storms, or grey skies.
What Actually Makes a State’s Weather “Best”?
There’s no single official definition, but most credible rankings converge on four factors: average temperature relative to a comfortable range (commonly cited as roughly 63°F to 86°F), annual sunshine hours, humidity levels, and the frequency of severe weather events such as hurricanes, tornadoes, or blizzards. A state can score well on one factor and poorly on another, which is exactly why different sources produce different “winners.”
It’s worth mentioning that raw average temperature is a poor stand-in for comfort on its own. NOAA’s 1971 to 2000 climate normals, compiled by World Population Review, show Florida (70.7°F) and Hawaii (70.0°F) as the two warmest states by average temperature, ahead of California (59.4°F).[1] Yet most broader rankings still favor California overall, because they also weight low rainfall, low humidity, and mild seasonal swings, not just heat.
That distinction matters for anyone using this kind of data to make a real decision. A state that’s warm year-round isn’t automatically pleasant if it’s also humid, storm-prone, or subject to long hurricane seasons.
How the Rankings Actually Work
- Start with a temperature baseline. Most methodologies score states on how close their year-round average sits to a comfortable range, rather than simply how warm they are.
- Add sunshine and cloud cover. States are scored on annual sunshine hours or sunshine percentage, since two states can share a temperature range but differ sharply in how often the sun actually shows up.
- Factor in humidity. High humidity makes warm temperatures feel worse and cold temperatures feel damp, so it’s weighted separately from temperature in most serious methodologies.
- Subtract for severe weather. Hurricane frequency, tornado activity, and major storm events pull a state’s score down even if its averages look good on paper.
- Combine and rank. The final order depends entirely on how heavily each factor is weighted, which is why California tops some lists while New Mexico or Arizona top others.
In practice, an analysis using this kind of composite scoring (temperature distance from 65°F, January sunshine, and storm event frequency) has ranked New Mexico first in at least one recent data-driven comparison, ahead of the more commonly cited California and Hawaii.[2] That’s not a contradiction; it’s a reminder that “best” is a function of the criteria you choose, not a fixed fact.
Benefits, Limitations, and Trade-Offs by State
No state wins on every measure. The table below summarizes the honest trade-offs behind the states that most consistently appear near the top of “best weather” rankings.
| State | Known for | Main trade-off | Best suited for |
|---|---|---|---|
| California (coastal) | Mild, low-humidity coastal climate; NOAA average 59.4°F statewide | Wildfire risk, high cost of living in coastal cities | People who prioritize mild, stable temperatures over heat |
| Hawaii | Warm, stable temperatures year-round; NOAA average 70.0°F | Isolation, high cost of living, occasional hurricanes | People who want minimal seasonal variation and don’t mind island living |
| Arizona | Abundant winter sunshine, dry heat | Extreme summer heat (often above 100°F for weeks) | People who dislike cold and humidity more than they dislike heat |
| New Mexico | Strong composite score on temperature, sunshine, and storm frequency | Higher elevation means colder nights and some winter storms | People who want a data-favored “middle ground” climate |
| Florida | Warmest average temperature in the continental US | Hurricane season, high humidity | People who prioritize warmth above storm risk and humidity |
This table isn’t exhaustive, and it deliberately leaves out states that rank well only on one narrow metric. If a state you’re considering isn’t listed, that doesn’t mean its weather is bad; it means it didn’t lead any of the major published rankings reviewed here.
Common Mistakes When Comparing “Best Weather” States
- Treating average annual temperature as the whole story. A state can have a pleasant yearly average while still having brutal summers or wet winters. Always check seasonal breakdowns, not just the annual figure.
- Ignoring humidity. Two states with similar temperatures can feel completely different depending on humidity. Gulf Coast heat and desert Southwest heat are not the same experience.
- Overlooking disaster risk. Wildfire, hurricane, and tornado exposure rarely show up in simple temperature-based rankings but matter enormously for anyone relocating long-term. [VERIFY BEFORE PUBLISHING: confirm current wildfire and hurricane risk figures against National Interagency Fire Center and National Hurricane Center data before citing specific frequencies.]
- Assuming one ranking is definitive. Because methodologies differ, it’s more useful to look at where a state appears across multiple independent sources than to trust a single “number one” claim.
- Skipping cost of living. Weather quality and affordability often move in opposite directions, particularly in coastal California and Hawaii.
Final Perspective
The states that dominate “best weather” lists earn that position by avoiding extremes, not by delivering perfection. Once you know which discomfort you’re least willing to live with, heat, humidity, storms, or grey winters, the “best” state stops being a ranking question and becomes a personal one.
Frequently Asked Questions
What is the best weather state in the US?
California is most often ranked as the best weather state overall, largely because of its mild coastal temperatures, low humidity, and relatively low storm frequency. Rankings that weight sunshine and storm-event data more heavily sometimes place Arizona or New Mexico ahead of it instead.
Which state has the warmest weather on average?
Florida has the highest average annual temperature among all US states, at roughly 70.7°F based on NOAA’s 1971 to 2000 climate normals, with Hawaii close behind at around 70.0°F. Warmest is not the same as most comfortable, since both states also carry humidity and hurricane exposure.
Does Hawaii or California have better weather?
Hawaii offers more consistent, less seasonal temperatures, while California offers lower humidity and a wider variety of microclimates within one state. The better choice depends on whether you prefer stability (Hawaii) or dryness and variety (California).
What states have the least extreme weather?
States with lower storm-event frequency and moderate temperature swings, such as California, Arizona, and New Mexico, tend to rank well for minimal extreme weather in composite data analyses. No US state is entirely free of severe weather risk; each carries a different type, whether wildfire, drought, or occasional storms.
Can weather affect health, and does that matter when choosing a state?
Weather patterns, particularly limited winter sunlight, are linked to Seasonal Affective Disorder (SAD) for some people, which is a recognized factor in relocation decisions for those affected. [VERIFY BEFORE PUBLISHING: confirm current CDC or National Institute of Mental Health guidance and link to the relevant official page before publishing.] Anyone managing a diagnosed mood disorder should treat this as one input among several, not a substitute for medical advice.
Is a state’s “best weather” ranking the same every year?
No. Rankings shift slightly year to year as climate data updates and as different organizations adjust their methodology, though the same handful of states (California, Hawaii, Arizona, and a few Southeastern and Southwestern states) tend to appear near the top consistently.
