Weather in Panama: Rains with Storms on Both Sides of the Country

Panama is bracing for a day of unsettled weather as the Institute of Meteorology and Hydrology of Panama (IMHPA) forecasts widespread rain accompanied by thunderstorms across both the Caribbean and Pacific regions on Saturday, July 4, 2026.

Incursions of cloud cover are expected to bring rain, particularly to the Caribbean coast, affecting areas like Colón province and Guna Yala. The IMHPA has issued a warning for the Caribbean coastline due to the anticipated weather conditions, which include heavy downpours. Meanwhile, the Pacific side will see rain and thunderstorms, especially in the Gulf of Panama, impacting southern Veraguas, the Azuero Peninsula, and the provinces of Panama Oeste, Coclé, Panama, and Darién.

As the day progresses, the storm activity is predicted to shift inland towards the Central and Western provinces during the afternoon. By nightfall, precipitation is expected to continue in Chiriquí, Bocas del Toro, and the Ngäbe-Buglé region. Other parts of the country are not anticipated to experience significant rainfall.

Temperatures will vary across the isthmus. Minimum temperatures are expected to be between 12°C and 18°C in the Central Mountains. In contrast, most other areas will experience lows between 23°C and 26°C. Maximum temperatures are forecast to reach between 28°C and 33°C along the Pacific coast, 27°C to 30°C on the Caribbean side, and 20°C to 26°C in the Central Mountains. Winds will generally be variable, blowing from the northeast to northwest and southwest to northeast at sustained speeds of 10 to 25 km/h.

Maritime conditions on the Caribbean coast will see waves ranging from 1.50 to 1.80 meters, with periods of 8 to 9 seconds, prompting a warning. The Pacific coast will experience calmer seas with waves of 0.90 to 1.30 meters and longer periods of 11 to 15 seconds. UV-B radiation levels are expected to remain moderate to high across the country.
