Las Vegas Hotels with Year-Round Heated Pools
One of Las Vegas's most underappreciated advantages as a travel destination is that pool season is genuinely year-round. The desert climate means even winter days are often sunny and mild, and all major Strip hotels heat their pools to comfortable swimming temperatures regardless of the season. I have swum at Mandalay Bay Beach in December and found it perfectly enjoyable — the water was warm, the sun was out, and the pool was blissfully uncrowded.

Tips for Winter Pool Swimming in Las Vegas
Go mid-morning. Las Vegas winter days warm up quickly after a cool morning. By 10–11am, even December days are often 60–65°F, which is perfectly comfortable for pool swimming when the water is heated to 82°F. The pool areas are also at their least crowded in winter mornings.
Choose a pool with good sun exposure. In winter, the sun is lower in the sky, and some pools are partially shaded by the hotel towers. Mandalay Bay Beach and Encore Beach Club have the best sun exposure in winter due to their open layouts. The Cosmopolitan's Boulevard Pool can be partially shaded in winter afternoons.
Book a cabana for warmth. Most Las Vegas hotel pools offer heated cabanas year-round. A cabana provides a warm retreat between swims and is worth the cost ($150–$400/day) for a winter pool day.
Frequently Asked Questions
Are Las Vegas hotel pools heated in winter?
Yes — all major Strip hotel pools are heated and technically open year-round. However, the experience varies significantly by season. In December through February, daytime temperatures in Las Vegas average 55–65°F, which is cool for outdoor swimming even with a heated pool. Most pools maintain water temperatures of 82–86°F year-round, but the ambient air temperature makes winter swimming less enjoyable than summer. Spring (March–May) and fall (September–November) offer the best combination of warm air temperatures and heated pools.
Which Las Vegas hotel has the warmest pool?
Mandalay Bay Beach maintains the warmest pool temperatures on the Strip, typically 82–84°F year-round. The wave pool and lazy river are also heated. Encore Beach Club and the Bellagio pool complex also maintain consistently warm temperatures. Indoor pools (available at some properties) maintain warmer temperatures regardless of outside conditions.
