Puerto Vallarta, Jalisco, September 10, 2026 — Light rain was falling in parts of Puerto Vallarta at 6:20 a.m. Central Time, with the temperature near 25°C (78°F).
The city is expected to reach about 34°C (93°F) this afternoon. The overnight low will remain close to 26°C (79°F). Humidity could push the apparent temperature toward 37°C to 38°C (99°F to 100°F) late in the day.
Rain chances increase during the late afternoon. One hourly forecast places the probability near 60% around 5 p.m., followed by a lower chance during the early evening. An isolated thunderstorm remains possible.
Tropical wave keeps rain in the forecast
The 6 a.m. forecast from Mexico’s National Meteorological Service identified Tropical Wave 37 over western Mexico. The heaviest rainfall forecast for Jalisco is concentrated in the state’s northern and eastern areas, outside Puerto Vallarta.
Puerto Vallarta’s local forecast calls for lighter, more scattered rainfall. Any afternoon storm could still bring lightning, briefly reduced visibility, and water accumulation on low-lying streets. Drivers should slow down if a downpour develops and avoid crossing water where the depth cannot be judged.
No tropical cyclone warning for Puerto Vallarta was listed in the 6 a.m. bulletin.
Heat will be more noticeable than the wind
Local wind should generally remain light to moderate, around 9 to 23 km/h (6 to 14 mph). Mexico’s national forecast allows for stronger regional gusts of 30 to 50 km/h (19 to 31 mph) in parts of Jalisco during storms.
The combination of heat and humidity will be the main concern for people working outdoors or walking during the afternoon. The hottest period is expected from noon through about 5 p.m.
Higher swell along the Jalisco coast
The national forecast calls for long-period swell of 1.5 to 2.5 meters (about 5 to 8 feet) along the Jalisco coast. Conditions will differ by beach depending on exposure and local currents.
Swimmers should follow lifeguard instructions and the posted beach flag. Elevated swell can strengthen rip currents even when breaking waves appear manageable from shore.
The swell forecast does not automatically mean Puerto Vallarta’s maritime port is closed. Anyone taking a fishing, sightseeing, or private boat trip should check the official port-status page before departure.
Best window for outdoor plans
Morning hours offer the better window for errands, exercise and beach plans before the heat builds. Carry water and plan for shade if remaining outside through the afternoon.
Keep rain protection nearby after 3 p.m. and check current radar before driving across town. Beach flags, port restrictions, and thunderstorm timing can change during the day.
