Puerto Vallarta, Jalisco, July 21, 2026 – Puerto Vallarta began Tuesday mostly clear to partly cloudy, with a temperature near 25°C (76°F) at approximately 6:25 a.m. local time.
Humidity was forecast near 85% around sunrise, making the morning feel slightly warmer than the thermometer indicated. The temperature is expected to reach about 34°C (93°F) this afternoon before falling to around 26°C (78°F) overnight.
The daily rain chance is around 40% to 50%, although rain is not expected to cover the entire city. Forecasts favor isolated thunderstorms around midday or during the afternoon, with another smaller chance of passing showers after 8 p.m.
Heat and Humidity Through the Afternoon
Temperatures should climb quickly after 9 a.m., reaching 32°C to 33°C (90°F to 92°F) during the early afternoon. The combination of heat and humidity could produce apparent temperatures near 40°C (104°F), especially in direct sunlight. The hourly forecast places the highest heat between noon and 4 p.m.
Winds should remain light to moderate, generally from the northwest at 5 to 16 km/h (3 to 10 mph). The ultraviolet index is forecast to reach extreme levels around midday, making shade, water and sun protection important for extended outdoor plans.
Rain, Lightning and Street Conditions
The latest official national outlook places the strongest Jalisco rainfall risk farther south, where accumulations of 25 to 50 millimeters are possible. It does not identify Puerto Vallarta under a separate city-level flood alert in the material reviewed before publication.
A thunderstorm forming directly over the bay or mountains could still bring lightning, a brief downpour, and temporary ponding on low-lying streets. Drivers should allow extra time if rain develops and avoid entering water-covered roads where the depth cannot be judged.
Jalisco Coast and Beach Conditions
The federal forecast calls for waves of 1 to 2 meters, approximately 3 to 6.5 feet, along the Jalisco coast between Tuesday morning and Wednesday morning. That is regional guidance rather than a reading for each Puerto Vallarta beach, and conditions inside Banderas Bay can vary significantly by location.
Beach visitors should follow the flag posted by lifeguards and avoid swimming near rocks, river mouths or areas with a visible current. Anyone with a fishing, excursion or private-boat departure should confirm conditions with the operator and check the federal port-status service before leaving, since navigation restrictions can change during the day.
A Practical Plan for Tuesday
The morning offers the most comfortable window for errands, exercise and longer walks. Outdoor plans from noon through the afternoon should account for humid heat and the possibility of a short thunderstorm.
Carry water, seek shade during the hottest hours, and keep rain protection nearby. Beach, boating and evening travel plans should be checked again later Tuesday because storm timing and coastal conditions may change.
