Puerto Vallarta, Jalisco, August 31, 2026 – Light rain was falling in Puerto Vallarta at 6:20 a.m. Central Time, with a temperature of 26°C (78°F). Humidity was near 81%, according to the morning hourly weather report.
Temperatures are forecast to climb to 34–35°C (93–95°F) this afternoon. Humidity will make it feel closer to 38°C (100°F) during the hottest part of the day. The overnight low will remain near 25°C (77°F).
Rain is expected to become more likely late Monday afternoon, with thunderstorms possible during the evening. Conditions may vary across the city and can change quickly.
Humid heat builds before the storms
Mostly cloudy skies are expected through the morning, with temperatures reaching 30°C (86°F) around 10 a.m. and 33°C (91°F) by noon.
The highest heat index is expected between 1 p.m. and 3 p.m. People working outside or walking long distances should plan extra water and shade during that period. The combination of heat and humidity will be more important than the air temperature alone.
Rain chances increase late in the day
The latest hour-by-hour forecast places the first notable rise in rain chances during the afternoon. Another city forecast gives Puerto Vallarta a 55% overall chance of rain Monday, with a high near 35°C (95°F).
The most likely window for showers and thunderstorms is from about 5 p.m. through 8 p.m., although an isolated storm could form earlier. Rain will be uneven, meaning one neighborhood may receive a heavy downpour while another sees little precipitation.
The national forecast from Mexico’s weather service calls for localized rainfall totals of 50–75 millimeters (2–3 inches) in parts of western Jalisco. That is a broad regional forecast, not a prediction that every part of Puerto Vallarta will receive that amount.
Any stronger storm may bring lightning, brief wind gusts and rapid street flooding. Drivers should avoid entering water-covered streets, especially after dark when the depth is difficult to judge. Runoff can rise quickly near rivers, streams and hillside drainage channels.
Light winds and a moderate southwest swell
Winds around Puerto Vallarta should remain light, generally below 11 km/h (7 mph). Local marine guidance for Banderas Bay shows northeast winds of 5–6 knots Monday morning, becoming light and variable during the afternoon.
The forecast calls for a south-southwest swell near 0.9 meters (3 feet) with a 13-second period. That does not indicate major surf, but currents can differ by beach. Swimmers should follow the flag posted at their beach and leave the water if thunder is heard.
Hurricane Karina remains far west of mainland Mexico and is moving farther into the Pacific. The latest hurricane guidance does not indicate a direct wind threat to Puerto Vallarta today.
The best window for outdoor plans
Morning through early afternoon offers the most dependable period for errands, beach time and outdoor work, although the heat will become uncomfortable before midday.
Anyone with late-afternoon or evening plans should carry rain protection and allow extra travel time. Storm development, beach flags and road conditions should be checked again later Monday because the forecast can change as local thunderstorms form.
