When your windows frame the crystalline creep of fresh frost and the forecast calls for snow, sleet and plummeting mercury, nothing boosts the spirit better than dreams of tropical heat and beachy vistas. But when even the weatherman looks depressed and the thermometer starts to shiver, it can be hard to remember what warm weather feels like, much less to envision sand between your toes and colorful drinks with fancy umbrellas. So we're here to help get you started on your armchair (or actual!) travels. These seven, ultra-luxurious infinity pools are absolutely spectacular and overlook the warmest oceans the world has to offer. Happy daydreams...

The Marriott Wailea Resort offers up the best of both worlds: family-friendly grounds and an adults-only infinity pool. And what an infinity pool it is! Calm waters cascade over the edge, drawing your eyes out to the sparkling Pacific. And if you’re in the market for a quiet place to relax, the infinity pool’s shaded cabanas and lounge chairs are the perfect choice.

Not only does the stylish Casa Colonial Beach and Spa sport an ocean-view infinity pool, but this four-pearl resort offers up ocean-view infinity whirlpools. That’s right: private, bubbly hot tubs that spill onto the golden beach and overlook Puerto Plata’s spectacular sea views – which are some of the best in the Dominican Republic! Even though Playa Dorada is jam-packed with 14 all-inclusive mega-resorts, you’d never know it at this secluded hot tub oasis.

There are six gorgeous pools at The Royal Hideaway Playacar, but the infinity pool is the most impressive. This five-pearl, adults-only resort is has a beautiful beachfront location, so guests can lounge oceanside while drinking in postcard-perfect views. Of course, you’re also invited to drink actual drinks, like fruity cocktails and ice-cold beers, courtesy of the pool’s bar service.

There are plenty of appealing features at the romantic and remote Hotel Punta Islita, but the eco-resort’s hilltop infinity pool definitely tops the list. Secreted away on a secluded peninsula, the exclusive hotel and its picturesque pool overlook lush rainforest and the Pacific Ocean. Guests can also expect an attractive deck with loungers and a swim-up bar.

Parrot Cay and COMO Shambhala Retreat, an oceanfront resort on beautiful Turks and Caicos, offers all-inclusive rates and an ultra-luxury experience. Among their top offerings: an oceanfront infinity pool with luxe loungers, plenty of shade, and spectacular Caribbean views. Whenever you’re ready for a change of pace, swap the pool for the sea and step out onto three miles of soft, fine white sands. In addition, all of the villas and houses have private pools, many with views to the sea.

The Ritz-Carlton is the definition of swanky elegance, and its St. Thomas locale lives up to the chain’s reputation in many ways. The resort’s beautiful infinity pool is jaw-dropping, with wonderful views of the ocean and beach. The cherry on top: St. Thomas’s best resort also offers poolside food and drink service, including rum shots and fresh fruit. Bottoms up!

This phenomenal luxury resort offers sincere, intimate hospitality and beautifully designed rooms by Ralph Lauren — not to mention one of the most gorgeous infinity pools we’ve ever seen.
