Puerto Vallarta, Jalisco, August 24, 2026 – At 6:10 a.m. CST, local weather feeds placed Puerto Vallarta between 25°C and 26°C (77°F and 79°F), with partly cloudy skies. The latest hourly conditions showed humidity near 86%, while a local forecast update reported a feels-like temperature of about 27°C (81°F).
The temperature is expected to reach about 34°C (93°F), with an overnight low near 25°C (77°F). The morning should remain mostly dry before scattered showers begin developing during the afternoon.
Forecast services differ on the exact rain odds. Current city forecasts place the chance near 30% to 50% from mid-afternoon, with probabilities around 40% to 60% during the evening. Thunderstorms are most likely late in the day and could continue around midnight.
Heat will peak before the storms
Humidity will make the afternoon feel hotter than the measured temperature. Heat-index readings could reach 38°C to 40°C (100°F to 104°F) between roughly 2 p.m. and 5 p.m.
Steady winds in the city should remain modest, generally around 5 to 15 km/h (3 to 9 mph). Local gusts may approach 22 km/h (14 mph) before any stronger winds associated with thunderstorms.
Regional forecast includes heavier rainfall
The National Meteorological Service forecast, issued at 2 p.m. Sunday and valid from 8 a.m. Monday through 8 a.m. Tuesday, calls for localized rainfall of 50 to 75 millimeters (2 to 3 inches) across portions of western and central Jalisco.
That is a regional maximum, not a citywide rainfall prediction for Puerto Vallarta. Stronger cells could still produce lightning, brief heavy rain, poor visibility and street flooding in low-lying areas. Regional wind gusts could reach 40 to 60 km/h (25 to 37 mph).
Drivers should avoid flooded crossings and standing water whose depth cannot be judged. Conditions near rivers, arroyos and hillside roads may change quickly during a heavy downpour.
Coastal conditions and Tropical Storm Iselle
The same official forecast calls for waves of 1 to 2 meters (3 to 7 feet) along the Jalisco coast. Conditions will vary by beach, so swimmers should follow the flag posted by lifeguards rather than assume the entire bay has the same conditions. Operators of small boats should confirm the current Puerto Vallarta port status before departure.
Tropical Storm Iselle remained far offshore early Monday. The latest National Hurricane Center advisory listed no coastal watches or warnings. It is not identified as a direct Puerto Vallarta threat in current advisories. Monday’s local rain risk is tied mainly to tropical wave 30 south of Jalisco and broader atmospheric instability.
Best window for Monday plans
Morning through early afternoon offers the most reliable window for errands and outdoor activity. Limit strenuous work during the hottest part of the afternoon, and allow extra travel time after 3 p.m.
Anyone heading to the beach should leave the water when thunder is heard. Weather, beach flags and port conditions can change during the day, so check again before afternoon travel or marine activities.
