Puerto Vallarta, Jalisco, August 4, 2026 – Conditions were mostly clear at 6:27 a.m., with a temperature of 25°C (77°F). The forecast calls for a hot, humid day, a high near 34°C (92°F), and a low around 26°C (79°F).
Afternoon storms possible
Rain chances vary among forecast services, but the main risk is expected from late afternoon into the evening. The hourly forecast shows isolated thunderstorms developing around 5 p.m., with showers possible through the evening. Another daily forecast places the chance of rain and thunderstorms at about 70%.
The weather pattern may produce brief downpours rather than continuous rain. Conditions can change quickly across the bay and surrounding mountain areas.
Heat and wind conditions
Humidity will make the afternoon feel hotter than the measured temperature. Hourly projections put the heat index near 39°C (102°F) during the warmest part of the afternoon.
Winds should generally remain light, but a regional weather report indicates that thunderstorm gusts near Puerto Vallarta could reach approximately 40 km/h (25 mph).
Beach, water and road planning
Lightning is the main concern for beachgoers, swimmers and boat passengers later in the day. Anyone planning water activities should check conditions shortly before leaving and move off exposed beaches or the water if thunder or lightning develops.
Short, heavy showers may temporarily reduce visibility and create standing water on streets, particularly during the evening commute. Drivers should allow extra time and avoid crossing moving water.
Planning your Tuesday
Outdoor plans are most likely to face interruptions after mid-afternoon. Carry rain protection, stay hydrated during the hottest hours, and check updated local conditions before heading to the beach, taking a boat, or driving during a storm.
