12 Best Warm Places to Visit in the USA in December
Weather information reviewed: 29 August 2026. Temperature ranges are rounded planning averages based primarily on long-term climate normals and tourism weather guidance—not a forecast for a particular December. Check the National Weather Service or another reliable forecast shortly before travelling.
December does not have to mean snow, icy roads and heavy winter coats. Travelers can still find tropical beaches, warm Florida sunshine and comfortable desert hiking weather without leaving the United States or its territories.
The best warm places to visit in the USA in December include San Juan, the US Virgin Islands, Honolulu, Maui, Key West, Miami, Naples, Orlando, Palm Springs, Phoenix, Tucson and San Diego. However, “warm” means something different in each destination. Puerto Rico, the Virgin Islands and Hawaii usually deliver genuine beach weather, while Southern California and Arizona are better for sunny outdoor activities with cool evenings.
This guide compares typical December temperatures, swimming potential, rain expectations, costs and activities so you can choose a destination matching the winter escape you actually want.

What Counts as Warm in the USA in December?
Travelers often use “warm” to mean three different things:
Tropical beach weather
Puerto Rico, the US Virgin Islands and warm coastal parts of Hawaii normally offer upper-70s to mid-80s daytime temperatures. These are the most dependable choices for swimsuits, snorkeling and warm evenings.
Warm Florida sunshine
South Florida and the Florida Keys generally reach the mid-to-upper 70s in December. Swimming is possible, but a passing cold front can bring cooler and windy conditions. Central Florida is comfortable for theme parks but not reliably tropical.
Mild outdoor weather
Palm Springs, Phoenix, Tucson and San Diego usually offer sunny afternoons in the mid-60s to low 70s with cool or cold nights. These destinations are excellent for hiking, golf and sightseeing—not guaranteed pool-and-beach heat.
NOAA’s current US Climate Normals use observations from 1991–2020 to describe typical monthly conditions. Climate normals are more useful for early trip planning than a forecast issued many months ahead.
1. St. Thomas or St. Croix, US Virgin Islands
Why visit in December?
The US Virgin Islands are normally among the warmest destinations under the US flag during December. Daytime temperatures commonly remain in the low-to-mid 80s, nights stay comfortably warm and the drier winter season begins.
St. Thomas offers convenient flights, shopping, beaches and access to nearby islands. St. Croix has a more spacious, locally rooted atmosphere with historic towns, diving and Buck Island excursions. St. John is another beautiful option, but most visitors reach it by ferry and accommodation can be costly.
The official Visit USVI site notes that US citizens can travel with many of the conveniences associated with domestic trips. Travelers should still verify identification requirements, return-flight rules and requirements for any side trip into the British Virgin Islands, which is a separate jurisdiction.
Typical December weather
- Daytime: Around 82–85°F
- Night: Around 73–76°F
- Rain: Brief tropical showers are possible, but December begins the more favorable winter period.

2. San Juan, Puerto Rico
Why visit in December?
San Juan combines tropical beaches with a historic old city, nightlife, food and easy day trips. Unlike a resort-only destination, it remains interesting during an occasional rain shower because visitors can explore forts, museums, architecture and restaurants.
Discover Puerto Rico describes December through March as slightly cooler and less humid while still warm. It is one of the strongest periods for outdoor sightseeing and beaches, although prices and crowds rise.
Typical December weather
- Daytime: Approximately 82–85°F
- Night: Approximately 72–76°F
- Rain: Short showers remain possible in a tropical climate.

3. Maui, Hawaii
Why visit in December?
Maui’s warmer coastal areas offer beach weather, scenic drives and a strong mix of relaxation and outdoor adventure. December is also part of Hawaii’s winter surf and whale season, although ocean conditions differ dramatically by coast.
The warmest and driest resort areas are generally on the leeward sides, including Wailea, Kihei and Kaanapali. Higher elevations, the summit of Haleakalā and windward areas can be much colder or wetter than beach-level averages.
Typical December weather
- Daytime near warm coasts: Approximately 79–82°F
- Night near warm coasts: Approximately 65–70°F
- Rain: Winter is wetter; leeward resort areas are commonly drier than windward zones.

- Visit Haleakalā National Park and carry warm clothing for the summit.

Cost and safety warning
December flights, rental cars and hotels can be expensive, especially during the holidays. Winter swells may produce dangerous surf. Never assume that warm air means calm water.
Best for: Couples, honeymooners and travelers combining beach time with dramatic scenery.
4. Honolulu and Oahu, Hawaii
Why visit in December?
Honolulu is often the easiest Hawaiian destination for visitors who want beaches plus restaurants, museums, public transportation and nightlife. Waikiki offers warm weather and beginner-friendly activities under suitable conditions, while the North Shore becomes famous for powerful winter surf.

Holiday travel can be extremely expensive. Early December often offers a better balance of weather, crowd levels and accommodation prices than the final two weeks.
Best for: First-time Hawaii visitors, families and travelers wanting an urban beach vacation.
5. Key West, Florida
Why visit in December?
Key West has the warmest winter climate among cities in the contiguous United States. The Florida Keys are surrounded by water, which moderates cold fronts more effectively than mainland Florida. December also falls within the drier part of the year.
The National Weather Service’s Florida Keys climate guidance explains that December through April receives only a relatively small share of annual rainfall and that surrounding warm water moderates winter cold.
Typical December weather
- Daytime: Approximately 75–78°F
- Night: Approximately 65–69°F
- Rain: Generally lower than in the wet season, though fronts can bring showers and wind.
- Water: Often acceptable for swimming, snorkeling or boating, but it can feel cool to heat-seeking travelers.

- See the Southernmost Point area early to avoid queues.

Cost and crowd warning
Key West can be one of Florida’s most expensive December destinations. Accommodation and parking are limited, and holiday-week prices rise steeply. Compare the full cost of driving the Overseas Highway with flying directly.
Best for: Couples and travelers seeking island atmosphere without leaving the contiguous US.
6. Miami, Florida
Why visit in December?
Miami offers warm afternoons, lower humidity than summer, beaches, international food and lively cultural neighborhoods. December is one of the most comfortable months for outdoor dining and city exploration.
South Florida cold fronts are usually short-lived but can bring cool mornings and windy beach conditions. This is a strong destination for travelers who want a warm city break even if every day is not perfect for swimming.
Typical December weather
- Daytime: Approximately 75–79°F

- Rain: Generally drier than summer.

7. Naples, Florida
Why visit in December?
Naples offers a quieter Gulf Coast alternative to Miami. The city is known for beaches, sunsets, outdoor dining and access to Southwest Florida nature. December usually brings lower humidity and comfortable afternoons in the 70s.
Typical December weather

Cost and crowd warning
Naples is warm but not necessarily cheap. Winter is popular with seasonal residents and visitors, so lodging prices can be high. Nearby Bonita Springs or Fort Myers may provide alternatives depending on the itinerary.
Best for: Couples, retirees and travelers prioritizing relaxation over nightlife.
8. Orlando, Florida
Why visit in December?
Orlando is not reliably tropical in December, but its mild daytime temperatures make long theme-park days more comfortable than humid summer visits. Holiday decorations and special events add seasonal appeal.
A cold front can temporarily drop daytime temperatures into the 50s or low 60s, and mornings may require a jacket. Heated hotel pools are more reliable than planning a natural beach day.
Typical December weather
- Daytime: Approximately 70–75°F
- Night: Approximately 49–55°F
- Rain: Usually lower than summer.
- Swimming: Heated pools are preferable; Orlando is inland.

Cost and crowd warning
The period from Christmas through New Year is among the busiest and most expensive times. Early December is usually the better choice for lower crowds and milder pricing.
Best for: Families and theme-park visitors who prefer mild weather over guaranteed beach heat.
9. Palm Springs, California
Why visit in December?
Palm Springs provides clear desert light, mid-century architecture, resorts, golf and comfortable hiking weather. Afternoon temperatures commonly approach 70°F, while evenings become cold enough for a jacket.
December is ideal for activities that are dangerously hot in summer. It is not, however, reliably warm after sunset, and hotel pools need to be heated for comfortable swimming.
Typical December weather
- Daytime: Approximately 68–73°F
- Night: Approximately 43–49°F
- Rain: Usually limited.
- Swimming: Best at a confirmed heated pool.
Best things to do

Can You Swim in the USA in December?
Most reliable swimming
Puerto Rico, the US Virgin Islands and Hawaii generally provide the best combination of warm air and warm water. Always check beach warnings, currents and surf conditions.
Often possible but weather-dependent
Key West, Miami and Naples can support beach swimming, especially for visitors from colder climates. Cold fronts, wind and individual comfort levels affect the experience.
Heated pool recommended
Orlando, Palm Springs, Phoenix and Tucson are better with a heated pool. Confirm heating policies directly with the hotel because “pool available” does not automatically mean comfortably heated.
Ocean usually chilly
San Diego beaches are excellent for walking and sunsets, but the Pacific is normally too cold for casual swimming without a wetsuit.

Cheapest Warm Places to Visit in December
Warm weather and low prices rarely coincide during the December holidays. These strategies improve the odds:
- Travel in early December: The first two weeks are often cheaper than Christmas and New Year.
- Consider Tucson instead of Scottsdale: It is cooler but may offer better accommodation value.
- Compare Naples with Fort Myers or Bonita Springs: The surrounding area can provide alternative rates.
- Stay outside Key West: Upper or Middle Keys may cost less, but driving time changes the experience.
- Use San Juan as a base: It can offer more accommodation and dining choices than smaller Caribbean islands.
- Check Orlando before school holidays: Early December can be milder on both prices and crowds.
- Compare complete hotel totals: Include mandatory fees, taxes, parking and resort charges.

What to Pack for a Warm December Vacation
Even the warmest destinations need more than swimwear:
- Lightweight daytime clothing
- Swimsuit and cover-up for tropical destinations
- Light rain jacket or compact umbrella

- Comfortable walking shoes
- Light sweater for restaurants or windy evenings
- Warmer jacket for Arizona and California nights

Never pack according to the average temperature alone. Check the forecast several days before departure and adjust for wind, rain, elevation and planned activities.
How to Choose the Right Warm December Destination
Ask these questions before booking:
- Do you want actual swimming weather or simply freedom from snow?
- Are you comfortable with daytime warmth and cool nights?
- Does the hotel guarantee a heated pool?
- Are you travelling before or during the costly holiday period?
- Would rain spoil the trip, or are museums and restaurants acceptable backups?
- Do you need a rental car?
- Are beach surf and current conditions suitable for your abilities?
- Is the destination at sea level or high elevation?

Which US beaches are warm enough to swim in December?
Puerto Rico, the US Virgin Islands and Hawaii offer the most reliable December swimming conditions. Key West and South Florida may also be comfortable, but cold fronts and personal temperature preference matter.
Is Florida hot in December?
Florida is usually mild to warm rather than consistently hot. Key West and Miami often reach the mid-to-upper 70s, while Orlando averages in the low 70s and can experience chilly mornings after cold fronts.
Is Hawaii warm in December?
Yes. Sea-level daytime temperatures commonly remain in the upper 70s to low 80s. December is part of the wetter winter season, and high-elevation areas can be dramatically colder than beaches.
Is Puerto Rico part of the USA?
Puerto Rico is a US territory. US citizens travelling directly between the mainland and Puerto Rico generally do not need a passport, but they must carry identification accepted for air travel and verify current requirements.
Are the US Virgin Islands part of the USA?
The US Virgin Islands are a US territory. Requirements differ if a traveler continues to the nearby British Virgin Islands, so check rules for every jurisdiction in the itinerary.
Is Arizona warm in December?
Arizona’s lower desert cities are mild and sunny during the day, commonly reaching the mid-60s to around 70°F. Nights can fall into the 30s or 40s, so Arizona is better for hiking and golf than guaranteed swimming.
Is San Diego warm enough for the beach in December?
San Diego is pleasant for beach walks, picnics and sunsets, but typical highs are in the mid-to-upper 60s and the Pacific Ocean is chilly. It is not equivalent to tropical beach weather.
What is the cheapest warm US destination in December?
The answer depends on the departure city. Tucson, Orlando before school holidays and parts of Southwest Florida may provide better-value accommodation than Hawaii, Key West or the US Virgin Islands. Compare airfare and lodging together.
Is December a good time to visit Key West?
Yes. December usually provides warm, relatively dry weather, but it is peak season and holiday prices can be high. Early December often offers better value than Christmas week.
Final Verdict
For the warmest possible December vacation under the US flag, choose Puerto Rico or the US Virgin Islands. Hawaii is another excellent tropical option, especially when beach time is combined with scenery and outdoor adventure.
Within the contiguous United States, Key West is the strongest choice for dependable warmth, while Miami and Naples provide pleasant South Florida sunshine. Orlando is better for theme parks than tropical swimming.
Palm Springs, Phoenix, Tucson and San Diego are ideal when “warm” means sunny outdoor weather rather than intense heat. Pack layers for cool evenings and choose a heated pool if swimming matters.
No destination can guarantee perfect December weather. Use long-term averages to choose the right climate, then check the short-range forecast, water conditions and local advisories before departure.
