Which San Diego hotels have a heated pool?

Most resort pools in San Diego are heated, including Paradise Point (five heated pools), Hyatt Regency Mission Bay, San Diego Mission Bay Resort, the Marriott Marquis San Diego Marina (two heated pools), and the Sheraton San Diego Resort on Harbor Island (three). Heated means the water is warm, but you are still under open sky, so on a gray, overcast morning a heated outdoor pool is most comfortable once the marine layer burns off.

What temperature are San Diego hotel pools kept at?

Most San Diego hotel and resort pools run in the high 70s to low 80s, roughly 78 to 82 degrees, with hot tubs and spas much warmer at around 100 to 104 degrees. Embassy Suites La Jolla's indoor atrium pool sits near 82. A few pools are deliberately kept cooler in the off-season, like the Sheraton's Lanai pool at around 60 degrees. Always confirm the current temperature with the hotel if it matters for your trip.

Are San Diego hotel pools heated year-round?

Many are, but not all, so check the specific hotel before you book. Resort-style properties like Paradise Point and Hyatt Regency Mission Bay heat their pools through the winter. Some hotels keep a secondary pool cooler in the off-season, so if you are traveling between late fall and spring, ask which pool is heated.

Are indoor pool hotels in San Diego good for kids?

Yes, especially on a cool morning. DoubleTree Mission Valley's indoor pool is a reliable rainy-or-gloomy-morning option for families. If your kids want slides and splash features instead, Hyatt Regency Mission Bay has three water slides and a dedicated kids' pool, and San Diego Mission Bay Resort has a waterfront pool plus a separate wading pool for little ones, though both of those are outdoor.

Can you use a San Diego hotel pool in winter?

Yes. Because the climate is mild, most San Diego hotels heat their pools year-round, so you can swim in December or January. The water stays warm, but the air is cooler, so a sunny early-afternoon swim is the comfortable move in the winter months. If you want to swim no matter the weather, book a hotel with a true indoor pool.

San Diego Hotels With Indoor & Heated Pools (2026 Guide)

Q: Which San Diego hotels have a true indoor pool?

Only a few. The ones we can confirm are enclosed and swimmable in any weather are Embassy Suites San Diego La Jolla (glass-roofed atrium pool, heated to around 82 degrees), Embassy Suites San Diego Bay Downtown, DoubleTree by Hilton San Diego Mission Valley (it has both an indoor lap pool and a heated outdoor pool), and the Marriott Vacation Club downtown (a small 12th-floor indoor pool). Most other San Diego hotel pools are heated outdoor pools, not indoor.

If you want a hotel pool you can use no matter what the weather does, look for a true indoor pool, and in San Diego that list is short. Most San Diego hotels have heated outdoor pools, which is a different thing, and the booking sites blur the two constantly. We have lived in San Diego for 25 years, and we have stayed at or poked our heads into a lot of these properties. Here is the real distinction, plus our picks for an indoor or heated pool by neighborhood.

The short answer: Genuinely indoor (enclosed) hotel pools are rare in San Diego because the climate supports outdoor swimming almost year-round. The hotels we can confirm have a true indoor pool are Embassy Suites San Diego La Jolla, Embassy Suites San Diego Bay Downtown, DoubleTree by Hilton San Diego Mission Valley (indoor and outdoor), and the Marriott Vacation Club downtown. Everywhere else on this page has a heated outdoor pool, and most of those run a warm 78 to 82 degrees.

Indoor pool vs. heated pool in San Diego: what’s the difference?

This trips up a lot of visitors, so it is worth a plain answer. An indoor pool is enclosed under a roof, so it is swimmable on a gray, cool, drizzly morning regardless of the sky. A heated outdoor pool keeps the water warm, but you are still standing under open sky, so on an overcast morning you are swimming in warm water under cool conditions until the marine layer burns off.

When this matters most: “June Gloom” is our local marine-layer pattern that leaves coastal mornings overcast and cool, and while it peaks in late spring and early summer, a gray marine layer can roll in on any morning and lingers through the winter too. On those days a heated outdoor pool is genuinely great here, you just use it in the warmer afternoon window once the sun is out. If your trip depends on swimming first thing in the morning, or you have kids who will not wait, that is when an indoor pool earns its keep.

San Diego hotels with a true indoor pool

These are the few hotels where you can genuinely swim under a roof, which is exactly what you want on a gloomy morning.

1. Embassy Suites San Diego La Jolla

The strongest indoor pool story in the city. The pool sits under a glass-roofed atrium, heated to around 82 degrees, with the koi pond and waterfalls that make this Embassy Suites feel like its own little world. There is an outdoor hot tub on the sundeck, but the pool itself is genuinely indoors, so the weather outside does not matter.

Neighborhood: La Jolla / UTC (University City), near Westfield UTC and a short drive to La Jolla Cove.
Parking reality: It is a self-park/valet hotel in the UTC office corridor. Use the on-site garage, do not try to street-park out here.
Best time to go: Mornings, before the breakfast-suite crowd filters down to the pool. This is your go-to when the marine layer is sitting on the coast.
The local move: This is the one we point visitors to when someone specifically asks for an indoor pool. It is close enough to La Jolla that you can swim in the morning and be at the Cove by lunch.

2. Embassy Suites San Diego Bay Downtown

A genuine indoor heated pool right on the Embarcadero, with the hot tub outdoors. For a downtown base where you can walk to the waterfront, Seaport Village, and the convention area, this is the indoor-pool pick.

Neighborhood: Downtown / Embarcadero, on Pacific Highway near the harbor.
Parking reality: Downtown valet/garage rates apply. If you are staying multiple nights and not driving much, factor the parking fee into your budget.
Best time to go: Evening swims work well here since the pool is indoors and the downtown day runs late.
The local move: Pair it with a morning harbor walk; you are steps from the bayfront path.

3. DoubleTree by Hilton San Diego Mission Valley

The value play, and our pick for families, because it has both. There is a true indoor lap pool next to the fitness center, plus a separate heated outdoor pool with a hot tub and fire pits on the deck. Gloomy morning, swim inside. Sunny afternoon, head out to the courtyard.

Neighborhood: Mission Valley, at Hazard Center, near the trolley and Fashion Valley mall.
Parking reality: On-site parking, and Mission Valley is the easy-driving, central part of town. This is the no-stress location of the bunch.
Best time to go: The indoor pool is the family fallback any time the marine layer or an evening chill shuts down outdoor swimming.
The local move: Mission Valley is the practical base for a first San Diego trip. You are 10 to 15 minutes from the beaches, downtown, and Balboa Park, and the trolley runs right there.

4. Marriott Vacation Club San Diego

A small enclosed indoor pool with a four-person jacuzzi on the 12th-floor amenity level of this downtown vacation-club tower near the Gaslamp. It is a timeshare property, but units rent, so it is worth knowing about if you want a downtown indoor pool for a longer stay. Availability comes and goes, so check dates before you count on it.

Neighborhood: Downtown, near the Gaslamp Quarter and Petco Park.
Parking reality: Downtown garage parking; expect a nightly fee.
Best time to go: Good for travelers who want kitchen-equipped units plus an indoor pool in walking distance of a ballgame.
The local move: If you are downtown for a Padres series and want a pool that works rain or shine, this is the quiet option most visitors never find.

San Diego hotels with a heated pool (outdoor)

If you are flexible on timing, these heated outdoor pools are some of the best in the city. They run a warm 78 to 82 degrees most of the year; just plan your swim for the sunny afternoon window when a marine layer is around.

5. Paradise Point Resort & Spa

Five heated pools on a Mission Bay island. This is the resort-day pick, with an adults-only pool if you want quiet and plenty of room for kids elsewhere. The pools are heated (the resort runs them 6am to 10pm), the setting is genuinely a getaway, and you are on the water.

Neighborhood: Mission Bay (Vacation Isle).
Parking reality: Resort self-park/valet with a daily fee. There is one way in and out of the island, so it stays calm.
Best time to go: Mid-to-late morning onward, once it warms up. Weekdays are far quieter than weekends.
The local move: You do not have to be a guest to appreciate the grounds, but the pools are for guests. If you want a Mission Bay resort feel, this is it.

6. Hyatt Regency Mission Bay

The kids’ pick. This is the San Diego resort known for water slides, with lagoon-shaped pools, three corkscrew slides, and a dedicated kids’ pool, and the pools are heated year-round. If your trip is really about keeping kids happy in the water, this beats a quiet indoor lap pool.

Neighborhood: Mission Bay, near SeaWorld and the bay-front bike path.
Parking reality: Resort parking fee; it is a big property so allow a minute to get from lot to pool.
Best time to go: Right when the pools open if you want a slide run before the lines. There is a height minimum for the big slides, so check before you promise the kids.
The local move: Combine it with a SeaWorld day, it is right there, and the bay path is great for a sunset ride.

7. San Diego Mission Bay Resort

Recently renovated and rebranded (this is the former Hilton San Diego Resort & Spa), with a waterfront pool plus a separate wading pool for little kids, and it is dog-friendly.

Neighborhood: Mission Bay.
Parking reality: Resort lot with a daily fee.
Best time to go: Afternoons for the warmth; the wading pool is easy for toddlers.
The local move: The bay-front location is made for morning walks before the pool opens up for the day.

8. Marriott Marquis San Diego Marina, Sheraton San Diego Resort, and the rest

The big downtown and Harbor Island hotels round out the heated-pool options. The Marriott Marquis San Diego Marina has the largest pool deck downtown, with two heated pools (one adults-only), a children’s pool, and a whirlpool right by the convention center and the marina. The Sheraton San Diego Resort on Harbor Island (formerly the Sheraton San Diego Hotel & Marina, freshly redone in a 2024 renovation) has three outdoor pools with marina and airport-runway views, though note its Lanai pool runs cooler (around 60 degrees) in the off-season. The Residence Inn San Diego La Jolla (heated outdoor, good for extended stays), Best Western Yacht Harbor Hotel in Point Loma, and Wyndham Garden Near SeaWorld fill out the budget-to-mid range, all with heated outdoor pools.

The trap to skip

Do not trust an aggregator’s “indoor pool” tag without checking. Booking sites routinely label heated outdoor pools as “indoor,” and the suburban chains people assume have indoor pools (the Hampton Inns, Residence Inns, and Homewood Suites out in Kearny Mesa, Carlsbad, and Sorrento Mesa) almost all run outdoor pools here. If a true indoor pool is a must, confirm it on the hotel’s own site or in recent guest photos before you book.

And one specific heads-up: the San Diego Marriott Gaslamp Quarter does not have a pool at all, just a fitness center and the Altitude rooftop bar, despite turning up in “hotels with pools” lists. If you want a downtown pool, look at the Marriott Marquis, the Embassy Suites Bay Downtown, or the Marriott Vacation Club instead.
