Weekly outlook


From June 12 to June 18, 2025

General Review

During this period, an unstable weather pattern is expected across much of the country due to several factors. The Intertropical Convergence Zone (ITCZ) will remain very active, and the passage of Tropical Wave #5, expected on Friday, will combine with high humidity levels in the atmosphere.
Additionally, a low-pressure system is anticipated to strengthen near the country over the Pacific Ocean during the weekend. This will generate a moist airflow from the west, leading to increased cloudiness, cooler temperatures, and variable rainfall in different regions.
Rainfall is expected to begin in a scattered manner during the mornings, especially in coastal areas. In the afternoons, downpours accompanied by thunderstorms are likely in the Pacific, Central Valley, Caribbean mountains, and Northern Zone. The Pacific regions could be the most affected by these conditions.
Precipitation may extend into part of the nighttime period, mainly in coastal areas of the Pacific and mountainous sections of the Central Valley. Additionally, occasional fog banks are anticipated to form in the Greater Metropolitan Area (GAM).

Forecast

Mornings: Partly to mostly cloudy skies with scattered showers, mainly in coastal areas. Cooler temperatures compared to the average.
Afternoon: Partly to mostly cloudy conditions with a chance of variable rainfall across most of the country. Isolated downpours in the Pacific slope, Central Valley, and mountainous areas of the Caribbean and Northern Zone. Possible fog banks in the Central Valley.
Night: Partly to mostly cloudy nationwide. Scattered showers in the mountainous areas of the Central Valley and coastal downpours in the Pacific during the early hours. Occasional rainfall possible in the Caribbean. Fog banks may form in the Central Valley.
