Weekly outlook


From April 28 to May 4, 2025

General Review

Humid and unstable atmospheric conditions prevail in the region and will favor the presence of precipitation in certain regions of the country.

High atmospheric pressure prevails in the Caribbean Basin, generating moderate trade winds this Monday and Tuesday. This allows the entry of moisture from the Caribbean Sea into the province of Limón and the Northern Zone, promoting cloudiness and the possibility of rain during the first days of the week. The intensity of the trade winds tends to decrease starting Wednesday, while precipitation decreases in these regions.

Meanwhile, the Intertropical Convergence Zone is beginning to show greater activity and is gradually approaching the southern part of the country. This, combined with warm morning temperatures, will facilitate the development of cloudiness and the occurrence of showers and thunderstorms during the afternoons in the South and Central Pacific. This activity may extend to the Nicoya Peninsula, the Tempisque Valley, and the Central Valley.

Forecast

Mornings: Partly cloudy in the Pacific and Central Valley, moderate trade winds in Guanacaste and the GAM on Monday and Tuesday. Cloudy cover and occasional rain showers are expected in the Caribbean and the North Zone on Monday and Tuesday, with a tendency to decrease starting Wednesday.

Afternoons: Partly cloudy in the North Pacific, with possible showers in the peninsula, and moderate winds in the northern zone on Monday and Tuesday. Isolated showers and thunderstorms are expected in the Central and South Pacific. The forecast will remain partly cloudy in the Central Valley, with possible scattered showers. In the Caribbean and the North Zone, partly cloudy conditions are expected, with possible rain in the mountains.

Nights: Partly cloudy in the Pacific and Central Valley, with possible rain and thunderstorms in coastal areas of the Central and South Pacific. Occasional gusts of wind are expected in Guanacaste and the mountains of the GAM on Monday and Tuesday. In the Caribbean and the North Zone, mostly cloudy are expected with rain on Monday and Tuesday; partly cloudy from Wednesday onwards.
