Puerto Vallarta, Jalisco, August 14, 2026 – Puerto Vallarta began Friday warm and humid under mostly clear skies. At 6:10 a.m., the local weather reading was 27°C (81°F), with a heat index of 29°C (84°F), humidity at 78%, and a light east-southeast wind at 5 km/h (3 mph).
Temperatures are expected to reach about 35°C (95°F) during the early afternoon. Forecasts place the heat index between 39°C and 41°C (102°F and 106°F) during the hottest part of the day.
Puerto Vallarta’s rain chance remains low through the morning. The hourly city forecast shows a 10% to 20% chance of an isolated thunderstorm between roughly 3 p.m. and 8 p.m., peaking near 7 p.m.
Heat and humidity peak after midday
Temperatures should pass 32°C (90°F) by late morning and remain above 33°C (91°F) through much of the afternoon. Humidity will make direct sun and physical activity feel hotter than the air temperature suggests.
The ultraviolet index is forecast to reach extreme levels around midday. Outdoor work, exercise, and longer walks will be more comfortable before 10 a.m. or later in the evening.
Winds should remain light to moderate at 5 to 13 km/h (3 to 8 mph), with possible gusts near 29 km/h (18 mph).
Local rain chance remains uncertain
Mexico’s federal forecast for August 14 calls for afternoon rain and thunderstorms across parts of western, central and eastern Jalisco. It allows for localized totals of 25 to 50 millimeters, along with lightning and stronger wind near storms.
That regional forecast does not mean Puerto Vallarta will receive that amount. City-level guidance keeps the local probability much lower, but residents should watch for clouds building over the mountains during the afternoon.
Any storm that reaches the city could briefly reduce visibility and cause standing water on low-lying streets. Drivers should avoid crossing a street where moving water obscures the pavement.
Elevated surf along the coast
The federal marine outlook forecasts long-period swell of 1.5 to 2.5 meters (5 to 8 feet) along the Jalisco coast. Beach conditions can vary around Banderas Bay, particularly between sheltered beaches and exposed stretches of the South Shore.
Swimmers should check the flag posted at each beach and stay out of the water where lifeguards restrict entry. Elevated swell can produce stronger shore break and currents even when skies remain clear.
Plan outdoor activities for the morning
Friday morning offers the most reliable window for errands, beach walks, and outdoor work. By midday, heat exposure becomes the main concern, while the small thunderstorm risk develops later in the afternoon.
Carry water, use sun protection and keep an umbrella available for late-day plans. Weather, surf and beach flags can change quickly during the rainy season.
