Best Winter RV Destinations: Where It's Actually Warm in January

If you want warm days in January, your realistic RV choices are South Florida, the Rio Grande Valley and Gulf Coast of Texas, the low deserts of southern Arizona and southeastern California, and the San Diego coast. South Florida is the only region where nights stay reliably mild. Everywhere else, plan on warm afternoons and cool to chilly nights.

The numbers below are NOAA's 1991–2020 monthly climate normals for January, pulled from the official NCEI data service. They are 30-year averages measured at airport and cooperative weather stations, so any given week can run warmer or colder. Campgrounds at higher elevation than the station will usually be cooler.

January averages at a glance

This table sorts the main winter regions by the average January low, because overnight temperature is what decides whether you are running the furnace all night or sleeping with a window cracked.

Two things jump out. First, the desert stations have the biggest gap between day and night. The Desert Resorts station near the east end of the Coachella Valley averages a 71°F high and a 39°F low in January, a 32-degree swing. Second, the coastal stations stay much more even, which is why Florida and the Texas coast feel so different from Arizona even when the afternoon highs look similar.

South Florida: warmest nights, highest demand

Key West and Miami are the only stations in the table with average January lows above 60°F. Fort Myers and Tampa are a step cooler at night but still mild. If you want to sit outside after dark in shorts, this is the region.

The trade-off is demand. Florida's state parks and the better-known private parks fill early for January through March, and many winter visitors stay for a month or the whole season. Our Florida winter RV camping guide covers how to book state parks, what the Keys are like in a big rig, and where the Gulf side differs from the Atlantic side.

South Texas: Rio Grande Valley and the Gulf Coast

Brownsville, at the southern tip of Texas, averages a 72.6°F January high and a 53.1°F low, close to Tampa. Moving up the coast, Corpus Christi averages 67.9°F highs and Galveston 63.2°F. Inland San Antonio has similar highs to Galveston but colder nights, at 41.0°F.

The Texas coast also gets winter cold fronts that can drop temperatures sharply for a day or two, so pack layers even if the averages look friendly. Start with our Texas Gulf Coast winter RV guide for parks, beach camping rules and wind exposure.

Southern Arizona: dry, sunny, cool nights

Phoenix, Tucson and Yuma all average January highs between 66.5°F and 69.8°F. Yuma has the mildest nights of the three at 47.9°F, and Tucson the coldest at 40.8°F. Desert air cools fast after sunset, so even a 68°F afternoon can turn into a night where you want the furnace or a heated blanket.

Arizona's big advantage is variety. You can stay in full-hookup resort parks around Phoenix, state parks near Tucson, or on BLM public land near Quartzsite and Yuma, where the Bureau of Land Management runs Long-Term Visitor Areas with seasonal permits. Our Arizona winter RV camping guide breaks down the regions, and our boondocking for beginners post covers dry camping basics if you want to try public land.

California's low desert: Palm Springs, Borrego, the Colorado River

Palm Springs averages a 70.5°F January high and a 47.6°F low. Borrego Springs, next to Anza-Borrego Desert State Park, is nearly identical by day at 69.7°F and slightly cooler at night. Blythe, on the Colorado River at the Arizona line, averages 68.2°F and 43.2°F.

Elevation changes the picture fast. Twentynine Palms, at the north edge of Joshua Tree National Park, averages a 63.3°F high and a 41.8°F low, several degrees cooler than Palm Springs by day. Higher campgrounds inside the park can be colder still. The desert floor near Thermal is a reminder that low elevation doesn't guarantee warm nights: its average January low is 39.0°F.

California's state park reservation system and national park campgrounds both get busy in winter. Check each park's official page for current rules, length limits and closures before you go.

The San Diego coast

San Diego's Lindbergh Field averages 66.4°F highs and 50.3°F lows in January. That is less warm than the deserts by day, but much more even, with mild nights. Coastal campgrounds trade heat for scenery and ocean air. Our California coast RV camping guide covers the coastline in more detail, including how hard the popular state beach campgrounds are to book.

Places that look warm but aren't

Some popular snowbird stops are better as late-fall or early-spring stops than January bases.

• Las Vegas: average January high of 58.5°F and low of 40.5°F. Pleasant for sightseeing, but not shorts weather.
• St. George, Utah: average January high of 54.0°F and low of 28.4°F. That low is below freezing, so you need a plan for hoses, tanks and plumbing.
• Mobile and the central Gulf Coast: Mobile averages 61.5°F and 40.7°F in January. Fine for a cooler-weather winter, but not tropical.

If you will be anywhere with freezing nights, read our guide to protecting water hookups from freezing before you leave, and run through the winter RV camping checklist.

What changes about RVing in winter, even down south

A warm-weather destination doesn't make a winter trip feel like summer. A few things behave differently, and they affect how you pick a campground.

Shorter days

You get fewer daylight hours for driving, setting up and solar charging. Aim to reach camp well before sunset, especially at an unfamiliar park. Our post on arriving at an RV park after dark covers what to do when that doesn't happen.

Heating load

Desert nights in the 40s mean your furnace will run, and RV furnaces draw on both propane and your house battery. If you plan to dry camp, size your battery and propane for cool nights, not just warm days. Our RV battery guide for boondocking walks through the math.

Wind and fronts

Open desert and exposed coastline both get wind, and winter fronts can arrive quickly. Pull in slide-outs and awnings when gusts pick up, and know where you would go if a strong storm is forecast. Our severe weather plan is a good template.

Long stays change the math

Many winter visitors stay put for weeks. That makes monthly park rates, metered electric charges and dump access more important than they are on a weekend trip. Ask each park what is included before you commit.

How to choose your winter base

1. Decide what matters at night. If you want mild evenings outside, South Florida and the Keys are the only regions in the table with average January lows above 60°F. If you are happy with cool nights and a furnace, the deserts open up.
2. Pick hookups or public land. The deserts offer the most dry camping. Florida and coastal Texas lean toward hookup parks and reservations.
3. Match the length of stay to the booking style. A month or more points toward monthly-rate parks or BLM seasonal permits. A one-week trip points toward state parks and nightly bookings.
4. Check elevation. A campground a few thousand feet above the nearest weather station can be noticeably colder than the numbers here.
5. Book early. The well-known parks in all of these regions fill early for January through March.
6. Have a cold-snap plan. Even warm regions get cold fronts. Know how you will protect your water lines and keep warm if the furnace or power fails.
