Cabo San Lucas in April (2027): Whale Season's End, Warm Water & Post-Easter Calm

⭐ Best April window: the first half (for whales) or the second half (for calm). Early April still catches the tail of whale season with warm dry weather; with Easter falling in March in 2027, mid to late April offers warm water, calmer beaches, and steady prices.

Cabo San Lucas in April is a transition month, and a genuinely pleasant one. Whale season is winding down, the water is finally warming into comfortable swimming range, and the weather is dependably warm and dry. The usual April wildcard, Semana Santa, falls in March in 2027 (21 to 28 March, with Easter Sunday on 28 March), so April is post-Easter: only the first few days carry holiday traffic as Mexican school breaks wind down. After that, April leans toward shoulder-season calm with summer-like water.

💰 Average April hotel prices (Cabo San Lucas / Tourist Corridor, mid-range 4-star):
Early April (1 to 7 April, just after Easter): ~$186–199/night · Mid to late April (14 to 28 April): ~$188–193/night
Live median rates for the most-reviewed 4-star hotels in Cabo San Lucas and the Tourist Corridor (30 to 39 of 45 returned a rate each night), two adults, one night, pulled 20 October 2026. Room only, before taxes; rates for dates many months out are often placeholders.

So who is April for? We'd lean toward April for travellers who want warm swimmable water and great weather without March's spring-break and Holy Week rates, and who are happy to catch the very end of whale season rather than its peak. We'd book early April if you still want a realistic shot at whales, and mid to late April if calm beaches matter more. We'd only steer you to another month if peak whales are the whole point, in which case January through March deliver. Most people don't realize how much the water warms by April; it is the first month since autumn that feels genuinely inviting for a long swim.

Temperatures and rainfall are 1991 to 2020 normals for Mexico's Servicio Meteorológico Nacional station in Cabo San Lucas; water temperatures are typical values for the month.

Temperature and Humidity

April is warm, dry, and consistently sunny, with daytime highs around 30°C (86°F) and low humidity. Evenings are mild but can feel cool after dark, with lows near 15°C (60°F), so one light layer does the job the several you needed in midwinter did. It is comfortable for everything from desert tours to long beach afternoons, and the oppressive summer heat is still weeks away.

Rain Pattern

Rain remains a non-event. April sits at the dry end of the calendar, with effectively no measurable rainfall most years and dependable sunshine throughout. No weather backup needed for outdoor days.

Sea and Outdoor Conditions

The water is the headline improvement. Sea temperatures rise to 22–23°C (72–73°F), the warmest since autumn and finally comfortable for extended snorkeling and swimming without a wetsuit for many guests. Winter north winds are essentially done, so mornings and afternoons are calmer and boat conditions are smoother. As always, early departures are best for glassy water and light, but April's conditions are forgiving by Cabo standards.

Cabo Weather by Month: How April Compares

April marks the shift from peak winter season to warm shoulder season. Here is how it lines up against the rest of the year across the four factors that most shape a trip.

April 2027 is a calm shoulder month from start to finish. Semana Santa falls in March this year (21 to 28 March, with Holy Thursday on 25 March and Good Friday on 26 March), so only the first few days of April carry any holiday traffic.

• 1 to 4 April: the tail of the Easter break. Mexican school holidays usually run into the week after Easter, so domestic travellers linger for the first few days of the month. Whales are still around, and our live hotel sample shows no Easter premium (about $186 on 1 April and $199 on Saturday 3 April).
• Early to mid April: whale tail + calm. Whale season is still going, spring break and Holy Week are over, and rates have eased from their March highs. Our take: the best all-round window if you want a shot at whales with warm water and lighter crowds.
• Late April: warm-water value. Crowds thin, water is at its warmest of the season so far, and prices hold steady. A relaxed, good-value window, just with whales largely gone.

Our live sample of 4-star hotels puts April at about $186 to $199 a night all month, down from about $203 to $220 in mid-March, with no Easter spike in 2027. Flights ease from winter peaks once the holiday traffic of the first days clears. April was among the cheapest months for nonstops in our Cabo flight data. With Semana Santa in March this year, most of April is simply calm, warm, and steadily priced.

April is the closing chapter of whale season. The first week or two still produce good sightings, with lingering humpbacks and the occasional mother-calf pair, but numbers thin noticeably as the month goes on and most operators wind down whale-specific tours by late April. If whales are on your April wish list, the message is simple: go early and book a morning tour in the first week or two.

By late April, whale watching gives way to general boat tours, snorkeling, and the building sportfishing season. In our view, April is a "still possible but no guarantees" month for whales, best treated as a bonus rather than the reason for the trip.

Cabo Whale Watching Calendar

Humpback season in Cabo runs mid-December through April. Here is the month-by-month arc so you can see exactly where April falls.

If whale season's end is April's loss, warm water is its gain. After months of cool winter sea, April finally warms into the comfortable range, and that reshapes what the month is best for.

Beaches and Swimming

At 22–23°C (72–73°F), the Sea of Cortez is swimmable without a wetsuit for most guests, and the warming trend continues all month. Médano Beach in Cabo San Lucas stays the safest swimming bay, while the calmer Tourist Corridor beaches and the protected coves toward San José del Cabo are increasingly pleasant. As always, check local flag conditions before swimming on the Pacific side, where swell can still run.

Snorkeling and Diving

Warmer water means more comfortable, longer snorkeling and diving sessions than midwinter, with the good winter visibility largely holding. Pelican Rock and Chileno Bay are reliable snorkeling stops, and the day trips north to La Paz and Cabo Pulmo become more appealing as the sea warms. We'd give April the edge over the winter months for anyone whose trip centres on getting in the water rather than on whales.

What we'd prioritise in April

With whales winding down, April is the month the water takes over. We'd give the edge to snorkeling, diving, and beach days now that the sea is comfortably warm, plus the Playa Balandra day trip to La Paz. Desert activities like ATV tours, horseback riding, and the zipline circuit remain comfortable before the summer heat. If you still want whales, book the first week.

Beyond the headliners, a few experiences round out an April trip especially well, even if they don't have a dedicated guide on this site yet:

• Sunset catamaran cruise around El Arco: warm, calm April evenings make for some of the best sunset light of the year at Land's End.
• Whale watching + snorkeling combo (early April): catch the tail of whale season and warm-water snorkeling in one morning before the season closes.
• San José del Cabo Art Walk: the Thursday-evening gallery stroll runs into spring; check that it is still on late in the season.
• Whale shark swim day trip to La Paz: April is the tail of the La Paz whale shark season, so an early-month trip may still connect. See our La Paz whale shark guide.
• Cabo Pulmo snorkel or dive day trip: the warming water makes the marine park's reefs north of Cabo an appealing full-day option.

• Go early for whales. Whale season ends this month. The first week or two still produce sightings; by late April most whale tours wind down. Book a morning tour early in the month if whales matter.
• Easter is in March this year. Semana Santa 2027 runs 21 to 28 March, so April misses the Holy Week spike; only the first days of April, as Mexican school holidays wind down, run a little busier.
• This is the month the water gets good. At 22–23°C, many guests no longer need a wetsuit for snorkeling, and swimming is comfortable. Lean into beach and water activities.
• Pack one light layer. Evenings dip to about 15°C (60°F), so a light cover-up is enough for sunset cruises.
• Mornings are still best on the water. Winds are light in April, but early departures give the calmest seas and best light.
• Book boat tours with free cancellation. A small habit that costs nothing and keeps you flexible.
• Arriving 1 to 4 April? Book tours a little earlier. Domestic holiday travel lingers into the week after Easter, so popular tours fill faster in those first days than later in the month.
• Adding Todos Santos in April? Our Todos Santos in April guide covers the Pacific side an hour north, which is rain-free and at its quietest once the Easter school holidays end in early April.
• Adding La Paz in April? Our La Paz in April guide covers the Sea of Cortez side farther north, as the whale shark season winds down.
• Visiting at a different time of year? April closes whale season; our Cabo in March guide covers the last full peak month, and Cabo in May covers the warm, quiet start of shoulder season. Whale season runs mid-December through April, while May onward trades whales for warmer water and lower prices.
