Puerto Vallarta, Jalisco, September 2, 2026 – As of 6:30 a.m. local time, hourly data for Puerto Vallarta showed mostly cloudy skies, a temperature near 26°C (79°F), humidity around 90% and a light east-northeast wind near 8 km/h (5 mph).
Temperatures are expected to reach 33°C (92°F) this afternoon before falling toward 25°C (77°F) overnight. An updated city forecast places the chance of an afternoon thunderstorm at 55%, with the apparent temperature approaching 41°C (106°F) during the hottest part of the day.
The 6 a.m. national forecast calls for rainfall totals of 25–50 millimeters, or roughly 1–2 inches, in parts of western Jalisco. It also forecasts 1.5–2.5-meter surf, about 5–8 feet, along the Jalisco coast.
Humid heat builds before the storms
Clouds may break at times during the morning, allowing temperatures to climb quickly from about 26°C (79°F) around sunrise to 31°C (88°F) or higher by midday.
Humidity will make the afternoon feel considerably hotter than the measured temperature. People working outdoors or walking longer distances should plan extra water and shade, even when cloud cover limits direct sunlight.
Afternoon rain may be uneven
The best chance for showers and thunderstorms begins after midday and continues into the early evening. Some neighborhoods may receive a brief downpour while other parts of the bay remain dry.
The SMN’s 25–50-millimeter forecast covers portions of western Jalisco. It is not a guaranteed citywide total for Puerto Vallarta. Any stronger cell could still produce lightning, reduced visibility and temporary flooding on low-lying streets.
Drivers should allow additional time during a downpour and avoid roads where the depth of standing water cannot be judged.
Marie contributes moisture and higher surf
Tropical Storm Marie remained well offshore early Wednesday. The 2 a.m. advisory placed its center about 700 kilometers, or 435 miles, south of the southern tip of Baja California. No coastal watches or warnings were in effect.
Marie is not forecast to approach Puerto Vallarta directly, but its broad circulation is contributing moisture and higher swells along Mexico’s central Pacific coast.
Conditions inside Banderas Bay can vary by beach. Swimmers should follow posted flags, while boat passengers should check the current port operating status before departure.
The better window for outdoor plans
Morning through midday offers the lower rain risk. Carry rain protection if plans extend into the afternoon, and leave the water when thunder is heard.
This forecast was updated at 6:30 a.m. local time. Storm timing, beach flags and port conditions can change during the day.
