Everyone thinks they want to move to Florida. It's the default setting. You get tired of scraping ice off a windshield in January, you see a picture of a palm tree on Instagram, and suddenly you're browsing Zillow for a condo in Naples. But honestly, "warm" is a relative term that people throw around way too loosely. If you’ve ever stood on a street corner in Houston in August, you know that "warm" can quickly turn into "I am melting into the pavement." It’s a spectrum. There is a massive difference between the dry, oven-like heat of the Mojave and the thick, soup-like humidity of the Gulf Coast.
Finding the right spot among the warm states in america isn't just about looking at a map and pointing south. It’s about understanding the nuances of microclimates. Some places are hot 365 days a year. Others are "winter-warm," meaning you can wear shorts in February, but you'll need a heavy-duty AC unit just to survive July.
We’re going to look at the data—real stuff from the National Oceanic and Atmospheric Administration (NOAA)—to figure out where the sun actually stays out and where the humidity won't ruin your life.
Why Florida Isn't the Only Game in Town
Florida gets the most press. Obviously. It has the highest average daily temperature in the country if you look at the year-round numbers. According to NOAA’s National Centers for Environmental Information, Florida averages about 70.7°F annually. That sounds perfect on paper, right? But the paper doesn't tell you about the 90% humidity that makes 85 degrees feel like 105.
If you want heat without the moisture, you look West. Arizona is the king of the "dry heat" argument. Phoenix hits over 100 degrees for more than 100 days a year. It’s intense. It’s the kind of heat that makes the steering wheel too hot to touch. Yet, because the dew point is so low, your sweat actually evaporates, which is your body's way of cooling down. In Miami? That sweat just sits there. You're basically a human sous-vide.
The Southwestern Reality Check
Arizona and Nevada offer a different flavor of warmth. Las Vegas and Phoenix are basically built on the idea that humans can conquer the desert with enough electricity. It works, mostly. But you have to consider the "Heat Island Effect." This is a real thing studied by the EPA where urban areas—think lots of asphalt and concrete—trap heat during the day and don't let it go at night. In Phoenix, the nighttime lows in the summer often stay above 90 degrees. That’s not a typo. It stays 90 degrees at midnight.

- Arizona: Extreme summer highs, beautiful winters, very low humidity.
- Nevada: Similar to Arizona but slightly cooler in the north (Reno gets actual snow).
- New Mexico: High-altitude warmth. It’s sunny, but Albuquerque gets chilly because it's 5,000 feet up.
The Humidity Factor in the Deep South
Let’s talk about the SEC states. Georgia, Alabama, Mississippi, and Louisiana. These are some of the most consistent warm states in america if you’re looking for long growing seasons and mild winters. If you hate snow, you’ll love it here. You might see a "dusting" once every three years that shuts down the entire city of Atlanta, but for the most part, your shovel will gather dust.
Louisiana is a swamp. I mean that in the most respectful, culturally rich way possible. New Orleans has a vibe you can't find anywhere else, but the air is thick. It’s heavy. When you walk outside in July, it feels like a warm, wet blanket is being pressed against your face. Texas is a whole different beast because it’s so huge. Brownsville, down at the very tip, is basically the tropics. Amarillo? That’s the high plains. It gets cold there. People forget that Texas has multiple climate zones.
Texas: A Climate Identity Crisis
If you move to Austin for the warmth, you're getting a mix of Hill Country breezes and blistering summer sun. It’s more humid than West Texas but drier than Houston. Houston is the humidity capital. It’s a massive economic engine, but the climate is essentially "wet heat." If you're moving for the weather, look at San Antonio or the Rio Grande Valley for more consistent, manageable warmth that doesn't feel like a sauna.
The California Dream vs. Reality
California is the most misunderstood state in the country regarding weather. People think "California" and see surfers in Malibu. But California is a massive vertical strip of land with wildly different temperatures. San Francisco is famous for being cold in the summer. Mark Twain (or whoever actually said it) wasn't lying about the coldest winter being a summer in San Francisco.
Southern California is where the "Mediterranean climate" lives. This is the gold standard. Places like Santa Barbara and San Diego have what many climatologists consider the most perfect weather on Earth. It stays between 60 and 80 degrees almost all year.

Wait, what about the fires?
That’s the trade-off. The same dry warmth that makes SoCal a paradise also makes it a tinderbox. The Santa Ana winds—hot, dry gusts that blow from the inland deserts toward the coast—can spike temperatures and drop humidity to single digits in hours. It’s a beautiful place to live, but you’re living with a certain level of environmental anxiety that you don't get in, say, Georgia.
Hawaii: The Forgotten Warm State
We often leave Hawaii out of the conversation because it's in the middle of the Pacific, but it is the only state in the U.S. that has never recorded a temperature below freezing at sea level. It’s the most thermally stable place in the country. Honolulu stays between 70 and 85 degrees pretty much forever. It’s remarkably consistent. If you want a state where "warm" isn't a season but a permanent state of being, Hawaii is the winner. Period.
Surprising Cold Snaps in Warm Places
One thing people get wrong about warm states in america is the "Freeze." In 2021, Texas had a massive power grid failure because of an ice storm. It was a freak event, but it proves a point: being a "warm state" doesn't mean you're immune to winter.
South Carolina and North Carolina are "warm-leaning." You get four seasons, but winter is short. Charlotte and Charleston are great for people who want a break from the heat in October but don't want to deal with six months of grey skies. The "Sun Belt" is popular for a reason. It’s not just the temperature; it’s the light. Northern states get "Seasonal Affective Disorder" because the sun sets at 4:00 PM and the sky is the color of a dirty sidewalk for months. In the South and Southwest, the sun actually shows up.
Average Days of Sunshine
| State | Sunny Days (Approx) | Humidity Level |
|---|---|---|
| Arizona | 300+ | Very Low |
| Florida | 230+ | Very High |
| New Mexico | 280 | Low |
| California (South) | 260 | Moderate |
| Georgia | 215 | High |
Assessing the Cost of Living in the Sun
Warmth costs money. Or rather, the type of warmth dictates your bills. In Arizona, you will pay a fortune in electricity from June to September to keep your house at 75 degrees. In Florida, your AC isn't just cooling the air; it's dehumidifying it. If your AC breaks in Florida, your house will grow mold in about 48 hours. Seriously.

Then there’s insurance. This is the big "hidden" cost of warm states. Florida’s home insurance market is currently in a state of chaos because of hurricane risk. California has similar issues with wildfire insurance. If you move to a warm state to save money, make sure you aren't just shifting your "heating bill" into a "quadrupled insurance premium."
The "Hidden" Warmth of the Carolinas
If you’re looking for a middle ground, the "Mid-South" is becoming the new destination. South Carolina—specifically the Lowcountry—offers that classic southern warmth with slightly more reasonable insurance (away from the coast) and a slower pace of life. Greenville, SC, is seeing a massive influx of people who want the sun but don't want the 100-degree spikes of the deep desert.
Actionable Steps for Choosing Your Warm State
Don't just move based on a vacation you took in July. Vacations aren't real life. If you’re serious about relocating to one of the warm states in america, you need a strategy that goes beyond looking at a thermometer.
- Check the Dew Point, Not Just the Temp: High humidity (a dew point over 65-70) makes heat feel oppressive. If you have respiratory issues or just hate feeling "sticky," stick to the High Desert (NM, AZ, NV).
- Visit in the "Worst" Month: Thinking about Phoenix? Go in August. If you can’t handle it then, you won't handle living there. Thinking about Miami? Go in September when it's humid and stormy.
- Analyze the Insurance Landscape: Before buying property, get an insurance quote. In many warm states, your mortgage might be affordable, but your escrow will kill you because of rising premiums.
- Look at the "Hardiness Zones": If you like gardening, look at the USDA Hardiness Zones. Warm states like Georgia (Zone 8) allow for amazing gardens, but the heat can actually kill some plants that thrive in cooler climates, like peonies or certain types of grass.
- Consider the "Cold" Days: Even in warm states, homes aren't always built for the occasional freeze. Check if the house has proper insulation. Many Florida homes are "concrete blocks" that stay cool in summer but turn into refrigerators during a rare 40-degree night.
Living in a warm state is a lifestyle choice that trades "winter blues" for "summer sweats." For most, it's a trade worth making. Just make sure you know which version of "warm" you're actually signing up for. Whether it's the salt air of the Keys, the red rocks of Sedona, or the rolling hills of Austin, the sun is out there. You just have to decide how much sweat you’re willing to tolerate to see it.
