La Paz in May (2026): Sea Lions, Warm Water, Weather & Travel Tips

⭐ Best May window: the whole month is warm, quiet, and good value, with sea lions open all month. If snorkeling with the Espíritu Santo sea lions is on your list, May is your last full chance before the colony closes around June 1.

La Paz in May is the warm, easygoing start of the low season. The whale sharks have moved on, but the water is now genuinely warm, the Espíritu Santo sea lion colony is still open, mobula rays are starting to gather off the islands, and the city is quiet and affordable. Days are hot and sunny, evenings are softened by the first Coromuel breezes, and the beaches and snorkeling are at their most inviting of the year so far. It is a different La Paz from the winter wildlife season: less about a single headline animal, more about warm-water days and value.

💰 Average May hotel prices (La Paz, mid-range 3–4 star):
Mid-range waterfront and downtown hotels: ~$100–140/night
Rough mid-range estimates; La Paz's low season runs well below Cabo, with budget and boutique options on either side.

So who is May for? We'd lean toward May for warm-water travellers and value-seekers who want quiet beaches, sea lions, and great snorkeling rather than the winter whale shark show. We'd book May specifically if the Espíritu Santo sea lions are a must-do, since this is the last full month before the colony closes for pupping. We'd only steer you away from May if you came for whale sharks, which are gone until October, or if you are very sensitive to heat, since the midday sun is strong now. Most people don't realize the sea lion colony closes for the summer; if that encounter matters to you, May is the window.

Is May a good time to visit La Paz? In short, yes, if you want warm water and value over winter wildlife: the whale sharks are gone, but sea lions, mobula rays, warm beaches, and low-season prices make it a rewarding month. Here is the quick snapshot before the detail below.

Temperature and Humidity

May is hot and dry, a clear step up from the spring. Daytime highs climb to around 31–33°C (88–91°F) under strong sun, but humidity stays low through most of the month, so the heat is the dry, manageable kind rather than the sticky summer version that arrives later. Evenings are pleasant, helped by the first Coromuel breezes, the warm southwesterly winds that blow off the bay at night and keep La Paz cooler after dark than its inland neighbours. Lows sit around 18–20°C (64–68°F).

Rain Pattern

There is essentially no rain. May is the tail of the long dry season, averaging zero rainy days, with clear, sunny skies every day. The humid, storm-prone weather is still a month or two away, so May is dependably dry.

Sea Temperature in La Paz in May

The sea temperature in La Paz in May is around 24°C (75°F), warm and pleasant, the best swimming and snorkeling conditions of the year so far. A wetsuit is optional for most people now, though some still wear a thin one for longer snorkel sessions. Seas are calm with the winter winds gone, and any afternoon breeze is gentle, so the water is inviting all day. What typically happens is that mornings are glassy and the lightest Coromuel breeze picks up in the evening.

La Paz Weather by Month: How May Compares

May sits at the warm, quiet start of La Paz's low season, after the winter wildlife window and before the humid heat of high summer. Here is how it lines up against the rest of the year across the four factors that most shape a trip.

May is when La Paz settles into its quiet low season. The winter wildlife crowds are gone, the summer domestic-holiday season has not yet arrived, and the result is one of the calmest, best-value months of the year.

• Early May (May 1–15): quiet and warm. The spring crowds have cleared, the weather is hot and dry, and sea lions and snorkeling are excellent. Rates are low and availability is easy across the board.
• Around mid-May: the only minor bump is the occasional long weekend; otherwise the month stays relaxed. Sea lion tours run all month right up to the June 1 closure.
• Late May (May 16–31): low season deepens. Heat builds toward summer and visitor numbers stay low, so this is prime time for value, with the last sea lion days of the season before the closure.

Expect mid-range La Paz hotels to run roughly $100–140/night in May, with budget guesthouses below and boutique waterfront properties above; this is noticeably cheaper than the winter whale shark season. La Paz remains a fraction of Cabo's rates year-round. Flights into Los Cabos (SJD) ease into low-season pricing, and La Paz is about a two-hour drive north, so book the shuttle or rental car ahead. Most guests find that May delivers winter-quality beach and snorkeling days at low-season prices, the trade being heat and no whale sharks.

With the whale sharks gone for the season, May's headline is the warm-water marine life around Isla Espíritu Santo. The Los Islotes sea lion colony is open and excellent, and because it closes around June 1 for the summer pupping season, May is the last full month to snorkel with the sea lions. The water is warm and clear, the playful juveniles are active, and the island day trips that reach the colony are running at full schedule.

May is also the start of the mobula ray season. Mobula rays (often called munk's devil rays) gather in growing numbers off La Paz and the islands through spring and early summer, sometimes leaping clear of the water in large groups, a spectacle that builds from May onward. Add reliably warm water, calm seas, and quiet beaches, and the month is a strong warm-water alternative to the winter wildlife show.

La Paz Marine Life by Season

La Paz is a year-round wildlife destination, but the headline animal changes through the year. Here is what is on in May and how the calendar runs.

• Espíritu Santo sea lion snorkel: the May must-do; a full-day island boat trip to snorkel with the Los Islotes colony in warm water before the closure. We'd book this first.
• Mobula ray trips: as the aggregations build, some operators run dedicated mobula snorkel outings; ask locally about current activity.
• Island and beach combos: warm water makes Espíritu Santo's coves and Playa Balandra superb for snorkeling and swimming, with or without the wildlife focus.

For the full island-tour comparison and what to expect with the sea lions, see our Isla Espíritu Santo tours guide. If the sea lions are your priority, book before the June 1 closure; for the whale shark season, see our La Paz whale shark guide and plan a return between October and April.

May is the hinge between spring and summer in La Paz, so the months around it pull in different directions, mainly on heat and what wildlife is available. Here is how May compares if your dates are flexible.

La Paz in May vs April

April still offers a late shot at whale sharks early in the month and is a touch cooler, while May has warmer water, no whale sharks, and lower low-season prices. Both have the sea lion colony open. We'd choose April if you want any chance at whale sharks, and May for warmer water, quieter beaches, and better value once the season has fully turned.

La Paz in May vs June

The big difference is the sea lions: the Los Islotes colony closes around June 1, so May is the last full month to snorkel with them, while June loses that headline. Both are hot, quiet, and good value, with June a little hotter and the water warmer still. We'd give May the clear edge for the sea lion encounter, and consider June only for warm-water beach and dive days at low-season prices.

La Paz in May vs July

July is deep summer: hotter, more humid, with the warmest water and the start of the storm-season build, and no sea lions. May is drier, a touch cooler, and still has the sea lions open. We'd choose May for comfort and wildlife, and July only if you specifically want the warmest possible water and bigger mobula ray aggregations, and can handle the humidity.

So when can you snorkel with sea lions in La Paz? The Los Islotes colony is open roughly September through May and closes around June through August for pupping season, so May is the last full month before the summer closure, and one of the best, with warm water and calm seas.

May's catches are about season, not weather damage. The conditions are warm and calm, but two things shape a May trip, and both are easy to plan around.

Building Heat

May is hot, with highs around 32°C (90°F) and strong midday sun, the start of the long Baja summer. Humidity is still low, so it is the comfortable, dry kind of heat, but it rewards an early start: do active tours and beach time in the morning, take a midday break, and enjoy the Coromuel-cooled evenings. Sun protection and hydration matter more now than in the mild winter months.

No Whale Sharks, and the Sea Lion Window Closing

If you came for whale sharks, May is the wrong month: the season runs October through April, and the animals are gone until autumn. The headline now is the Espíritu Santo sea lions, and even that window is closing, with the Los Islotes colony shutting around June 1 for pupping. The fix is simple: come in May rather than later in the summer if the sea lions matter, and plan a separate winter trip if whale sharks are the goal.

Note that hurricane season has not yet started. La Paz's storm season runs June–November, so May still carries effectively no hurricane risk; the only real consideration is the heat.

There is no shortage of things to do in La Paz in May: the sea lion colony is open for its last full month, the water is warm and calm for snorkeling and beaches, and mobula rays are building off the islands. Here is how the main activities rate this month.

What we'd prioritise in May

Do the sea lions first; May is the last full month before the June closure, and a warm-water snorkel with the Isla Espíritu Santo colony is the highlight of the month. After that, lean into the warm water: a morning at Playa Balandra, scuba diving in excellent visibility, and sportfishing as the dorado and tuna build. A La Paz food tour is the perfect cool-evening activity, and sandboarding works if you go early before the heat. For the complete menu, see our guide to the best things to do in La Paz.

Beyond the headliners, a few experiences round out a May trip especially well:

• Last-chance sea lion snorkel: the Los Islotes colony closes around June 1, so a May island trip is your final warm-water window to swim with the sea lions until they reopen in autumn.
• Mobula ray outing: as the spring aggregations build, a dedicated mobula snorkel can put you among hundreds of rays; ask operators about recent sightings.
• Espíritu Santo overnight or kayak camp: warm nights and calm water make May ideal for camping on the island's beaches and snorkeling its quiet coves.
• Early-morning Balandra beach day: the shallow turquoise bay is warm and quiet in low season; go early to enjoy it before the midday heat.
• Day trip to Todos Santos: the artsy Pacific pueblo mágico is a cooler, breezier escape on a hot day, with galleries, surf beaches, and a relaxed afternoon.

• Book the sea lions before the June closure. May is the last full month to snorkel with the Los Islotes colony, which shuts around June 1 for pupping season. Do not save it for a later summer trip.
• Start early to beat the heat. May days are hot with strong midday sun, so do tours, beaches, and active outings in the morning and keep midday for shade or a meal.
• Pack for sun, not cold. At 24°C the water is warm and a wetsuit is optional; bring strong sun protection, a hat, and plenty of water instead of winter layers.
• Ask about mobula rays. The spring aggregations are building, and some operators run dedicated trips; a few minutes asking locally can land you among hundreds of rays.
• Enjoy the Coromuel evenings. The warm southwesterly night breeze keeps La Paz comfortable after dark, so plan malecón walks, dinners, and food tours for the evening.
• Travel for value. May is low season with hotels well below winter rates, so it is a strong month to upgrade your stay or extend your trip.
• Consider basing in La Paz over Cabo. Low-season rates here are very low, and you are right by the islands, sea lions, and Balandra.
• Visiting at a different time of year? June continues the warm low season but loses the sea lions to the pupping closure, with mobula rays the headline: see our La Paz in June guide. For whale sharks, return between October and April: see our La Paz whale shark guide.
