Planning a trip to Puerto Vallarta in May puts you right at the edge of transition: where the dry season meets the beginning of warmer months. You'll find warm temperatures, calm waters, and sunny skies perfect for beach days and adventure tours.
This guide covers temperatures, rain patterns, ocean conditions, and how they affect your plans—plus what to pack and which activities work best in May's weather.
What's the Average Temperature in Puerto Vallarta During May?
May delivers genuine tropical warmth throughout the day. Daytime highs settle between 85-87°F, while nighttime temperatures drop to a comfortable 67-70°F. Expect warm mornings building into hot afternoons, then easing into pleasant evenings.
You'll experience about 15-19 degrees of variation between the coolest and warmest parts of the day, which means conditions shift noticeably as the sun moves across the sky.
How Hot Does It Get in Puerto Vallarta in May?
While air temperature peaks around 85-87°F during midday, the 68-75% humidity pushes the heat index into the low-to-mid 90s between noon and 4 PM. High moisture makes your body work harder to cool itself.
The sun hits hard with direct sunlight averaging 9.8 hours daily. Morning hours from 7-10 AM and late afternoon after 5 PM offer the most comfortable conditions for outdoor activities.
Is It Cold in Puerto Vallarta in May?
Puerto Vallarta doesn't experience cold weather during May. Even the coolest nighttime hours bottom out at a mild 67-70°F, comfortable enough for shorts and t-shirts. You won't need sweaters, jackets, or warm clothing for outdoor activities.
The only time you might want a light layer is inside heavily air-conditioned restaurants or shops, not because of outdoor temperatures.
What's the Temperature Like at Night in Puerto Vallarta in May?
Evenings remain pleasantly warm after sunset. Evening hours from 7-11 PM hover around 75°F—comfortable for beachfront dining and walks along the Malecón. Late night and early morning hours cool to 67-70°F. A light cardigan or thin long-sleeve shirt handles the occasional ocean breeze and overly air-conditioned restaurants, but you won't need substantial layers.
The evening warmth means outdoor activities stay comfortable well after sunset, extending your usable vacation hours beyond the hot midday period.

Is the Water Warm Enough to Swim in May?
Banderas Bay reaches some of its warmest temperatures during May, with ocean water averaging 81°F and occasionally climbing to 85°F. The water feels immediately comfortable. Perfect for swimming, snorkeling, and leisurely floating.
Wetsuits aren't necessary for surface activities, though scuba divers on longer, deeper dives sometimes prefer a thin 3-5mm wetsuit for comfort as temperatures drop at depth. The warm water also means children and less confident swimmers can enjoy the ocean without discomfort.
UV-protective rash guards make more sense than wetsuits during May—they protect your skin during long snorkeling sessions. The combination of warm water and good visibility creates ideal conditions for experiencing Banderas Bay's marine life.
Does It Rain in Puerto Vallarta in May?
Rain appears rarely during May, making it one of the driest months. With approximately 1 inch of rainfall spread across just one or two days, most of the month delivers nothing but sunshine. When showers do arrive, they tend to develop in late afternoon or evening rather than lingering through the day—brief bursts that drop their moisture and rarely last more than an hour. You won't experience the all-day soaking rains that characterize deeper rainy season months.
The dry pattern that defines November through April extends into May, even though the calendar technically marks the beginning of rainy season. This creates a predictable rhythm—clear mornings for activities, possible late-day showers that cool the air and refresh the landscape. A light rain jacket tucked in your bag covers occasional afternoon showers, but you can plan outdoor activities with confidence knowing weather disruptions are unlikely.
Is May Part of the Rainy Season in Puerto Vallarta?
May technically marks the beginning of rainy season, which runs from May through October. However, calling May a rainy month doesn't reflect actual conditions. The transition happens gradually—May retains most of the dry season's characteristics while humidity begins its slow climb. Real rainy season patterns don't establish themselves until June and intensify through summer and early fall.
May is the last reliably dry month, not the first wet one. The distinction matters for planning because May delivers dry-season reliability without peak-season crowds and prices.

Should You Worry About Hurricanes and Storms in Puerto Vallarta in May?
Hurricane concerns don't apply to May travel in any meaningful way. Peak hurricane activity occurs August through October, three to five months after May. Early-season storms in May are exceptionally rare.
May falls at the tail end of the dry season, meaning conditions needed for tropical storm development haven't yet aligned. You can book flights and tours without the storm anxiety that affects late summer and fall travel.
Is It Windy in Puerto Vallarta in May?
Moderate, consistent winds blow from the east and northeast throughout May, averaging 6.8-11 mph. Wind speeds are ideal—strong enough for sailing and water sports, gentle enough to stay enjoyable.
The steady breeze supports parasailing, paddleboarding, and sailing. Morning hours tend to be calmest, with winds building slightly through the afternoon—making mornings the ideal time for water activities where glassy conditions are preferred.
What Wildlife Shows Up in Puerto Vallarta in May?
May delivers abundant marine life encounters. Humpback whales depart for Arctic feeding grounds in late March, well before May arrives, so whale watching tours don't operate during this month. Dolphins maintain a year-round presence in the bay, and tour operators report regular sightings throughout May.
Sea turtles glide through snorkeling sites around Los Arcos and the Marietas Islands. Both manta rays and eagle rays appear regularly at popular dive sites, along with diverse tropical fish populations including angelfish, parrotfish, and moray eels. The warm water temperatures and excellent visibility create prime conditions for observing marine life in its natural habitat.
Does the Weather Affect Tours in Puerto Vallarta During May?
May's predominantly stable weather patterns mean tour cancellations are rare. With approximately 1 inch of rainfall and minimal disruption, water-based tours operate reliably most days.
Morning departures from 8-10 AM offer the calmest sea conditions and cooler temperatures before afternoon heat peaks. Snorkeling tours, diving, and sailing all benefit from May's warm ocean temperatures and excellent visibility.
What to Bring for Puerto Vallarta in May
May's conditions in Puerto Vallarta demand specific gear to stay comfortable. Lightweight, breathable clothing works for the consistent warmth, while a light cardigan or thin sweater handles air-conditioned restaurants and evening ocean breezes. UV-protective rash guards or lightweight long-sleeve shirts, a wide-brimmed hat, and quality sunglasses belong in every day bag. A reusable water bottle keeps you hydrated during the heat, and a light rain jacket provides coverage for rare late-afternoon showers.

Best Things to Do in Puerto Vallarta in May
May brings specific advantages to Puerto Vallarta. The warm ocean temperatures make water sports particularly appealing—snorkeling, paddleboarding, and swimming are ideal without wetsuits. Sailing benefits from consistent East to Northeast winds averaging 6.8-11 mph, creating optimal conditions for both propulsion and control across Banderas Bay.
The stable weather means adventure tours operate reliably for jungle canopy experiences and coastal exploration. Cultural activities and art walks along the Malecón stay pleasant during cooler evening hours.
