Planning a winter getaway doesn't mean you have to give up on swimming. While the majority of mega-resort pool complexes shut down when autumn ends, a select group of properties keeps their waters warm. If you're heading to Nevada during the final month of the year, knowing which spots maintain active swim schedules saves you from disappointment.
December weather in the desert brings crisp, sunny days with afternoon highs averaging around 60 degrees Fahrenheit, followed by chilly nights dropping into the high 30s. While sunbathing requires a bit of dedication, heated resort pools and high-tech aquatic amphitheatres remain open, offering comfortable water temperatures and uncrowded lounge chairs.
Which Major Las Vegas Pools Stay Open in December?
Most large multi-acre pool complexes drain their lazy rivers and shut down wave pools by November, but major operators typically keep at least one primary pool basin heated and accessible for registered hotel guests.
The Bellagio pool complex keeps select main basins open through the winter months, typically maintaining some of the warmest resort water on the Strip, heated up to 84 degrees. Similarly, Aria keeps its lushly landscaped pool deck operational, offering a peaceful oasis when the surrounding casino floors buzz with holiday crowds.
Other Strip locations offering winter swim access include:
- The Cosmopolitan: The quieter Chelsea Pool remains open during the winter season with adjusted hours.
- The Venetian and Palazzo: Elevated rooftop pool decks stay open year-round for guests wanting a splash with a view.
- Wynn and Encore: Portions of their pristine pool deck stay heated and open, though routine maintenance can occasionally shift access between towers.
- MGM Grand: While the massive lazy river closes for the season, the main pool stays open for swimmers.
Downtown Options and Multi-Level Aquatic Venues
If you want a vibrant atmosphere that ignores the winter chill completely, downtown Las Vegas handles December swimming differently than the standard resort model.
Circa Resort & Casino operates Stadium Swim, a massive multi-tier amphitheatre featuring giant screens and pools heated anywhere from 94 to over 100 degrees. Because the water acts more like a giant hot tub, it's easily the most popular spot for winter swimming in the city. It operates daily, attracts sports fans, and welcomes non-hotel guests for a cover charge.
Downtown Grand also keeps its Citrus Grand Pool Deck open through the winter months for a more relaxed, neighborhood vibe, though food and bar service may be scaled back compared to peak summer operations.
What to Expect From December Pool Rules and Amenities
Swimming in December comes with different rules, shorter hours, and adjusted service levels compared to a July trip. Understanding these nuances helps you avoid locked gates and cold walks back to your room.
Operating hours shrink significantly. While summer hours often span from 8:00 AM to 8:00 PM, winter pool hours usually run from roughly 9:00 AM or 10:00 AM to 4:00 PM. Once the sun dips behind the high-rise towers—which happens much earlier in the afternoon during December—temperatures drop fast, prompting staff to close the deck.
Towel service and cocktail stations also change. High-end properties usually provide fresh towels right at the gate, but poolside drink service might be limited to a walk-up bar or entirely self-service depending on weekday occupancy. Luxury dayclubs and sprawling daybeds are typically mothballed until spring, replaced by quiet rows of standard loungers.
Common Mistakes to Avoid When Planning a Winter Swim
- Assuming all pools at a resort are open: Just because a hotel website lists a year-round pool doesn't mean every body of water on the property is filled. Lazy rivers, adult-only coves, and VIP party lagoons close down systematically.
- Ignoring maintenance closures: December is the prime window for hotels to repaint basins, fix tiles, and service pumps. Always check with the front desk upon check-in to confirm which specific pool is active.
- Underestimating the walk back: Stepping out of an 84-degree pool into a 55-degree desert breeze is a shock to the system. Pack a warm robe, extra layers, and footwear that protects your feet from cold concrete.
- Trusting air temperature over water temp: A bright sunny day can feel warm, but wind speeds in the Las Vegas valley can make outdoor lounging uncomfortable if the water isn't properly heated.
Frequently Asked Questions
Can non-hotel guests use Las Vegas hotel pools in December?
Most standard resort pools are strictly restricted to registered hotel guests during the winter months to manage heating costs and lower occupancies. However, ticketed entertainment venues like Circa's Stadium Swim allow outside visitors for a fee.
Are the water slides and lazy rivers open in December?
No. Major attractions like the lazy river at MGM Grand and wave pools at Mandalay Bay are entirely shut down for seasonal maintenance and cold weather safety. Only basic rectangular or stylistic swim basins remain open.
What is the warmest pool in Las Vegas during winter?
Circa's Stadium Swim downtown maintains the highest water temperatures, often running between 94 and 100 degrees. Among traditional Strip properties, the Bellagio pools are famously heated up to a comfortable 84 degrees.
Do I need to make reservations for a winter pool day?
Usually, no. Because demand drops sharply in December, you rarely need a reservation or a paid cabana rental to secure a lounging chair. You can typically walk right up during open hours.
