Weekly outlook


From June 16 to 22, 2025

General Review

Several elements present in the atmosphere will foster humid and unstable conditions, a situation that will maintain the likelihood of precipitation.

This Monday, tropical wave 6 will cross Costa Rica and, combined with the proximity of the Intertropical Convergence Zone, will strengthen rainfall activity in different regions of the country, especially during the afternoon and extending into the late evening hours.

A low-pressure system in the Pacific Ocean, south of El Salvador, has a high potential for cyclonic development; at the same time, it will continue to migrate slowly northwestward. This system generates a supply of moisture to the national territory and will gradually diminish around Wednesday.

The typical rainy season pattern will take shape for the remainder of the period. A humid environment will prevail, and local factors such as morning warming and the arrival of sea breezes will favor isolated showers with thunderstorms during the afternoons and early evenings in regions of the Pacific, the Central Valley, the North Zone, and the Caribbean mountains.

Forecast

Mornings: Partly cloudy across the country. Possible rain in coastal areas during the early hours.

Afternoons: Cloudy and showers with thunderstorms are expected in the Pacific, the Central Valley, and the Northern Zone, with more widespread precipitation during the first part of the week. In the Caribbean, partly cloudy conditions are expected, with rain and showers in the mountains.

Nights: Cloudy cover and rain in the Pacific and Northern Zone. Scattered showers are expected in the Central Valley and Caribbean mountains during the first part of the night.
