Puerto Vallarta, Jalisco, August 29, 2026 – Light rain was falling at 6:50 a.m. Central time, with the temperature at 26°C (79°F), while today’s forecast calls for a high near 34°C (93°F) and an overnight low around 24°C (76°F).
The more likely rain window runs from late afternoon into early evening. The hourly forecast puts the chance near 20% to 25% through much of the morning, rising to about 50% to 55% between 4 p.m. and 7 p.m.
The 6 a.m. national bulletin places western, central and southern Jalisco in a 50 to 75 mm (2 to 3 inches) rainfall band, a regional forecast for possible peak totals rather than an expected accumulation across every part of Puerto Vallarta.
Heat and humidity build quickly
Humidity was forecast near 82% around 7 a.m. and should ease as the temperature climbs, although the afternoon heat index could approach 38°C to 39°C (100°F to 102°F).
The hottest period is expected from about 1 p.m. through 4 p.m., making earlier hours more comfortable for outdoor work, errands and exercise. Water and shade will still matter if cloud cover limits direct sun.
Rain and road conditions
The National Meteorological Service says storms in western Jalisco may include lightning and brief heavy rain, with stronger cells capable of producing street flooding, reduced visibility and faster runoff into rivers and streams.
Drivers should allow more time during downpours and avoid crossing water where the depth or current cannot be judged, since conditions may vary sharply between the coast, the city center and neighborhoods closer to the mountains.
The weather is linked to the Mexican monsoon, low-pressure channels and tropical wave 33; the 6 a.m. bulletin did not include a named tropical cyclone warning for Puerto Vallarta.
Wind, surf and beach conditions
Local hourly forecasts show light winds outside storms, generally 3 to 8 km/h (2 to 5 mph), while the national forecast says thunderstorm gusts elsewhere in Jalisco may reach 40 to 60 km/h (25 to 37 mph).
The official coastal forecast calls for waves of 2 to 3 meters (6.5 to 10 feet) along the Jalisco coast, but the forecast does not itself establish a beach or port closure. Swimmers and small-boat operators should check the flag posted at each beach and any instructions from lifeguards or the Port Captain immediately before entering the water or departing.
The best window for outdoor plans
Morning offers the better chance for errands, outdoor work and travel, although a passing shower remains possible; by mid-afternoon, carry rain protection and leave flexibility for lightning, heavier rain or temporary street flooding.
Conditions were checked at 6:50 a.m. Central time on Saturday, August 29, and forecast timing, beach flags and local restrictions can change during the day.
