General Review

An increase in humidity and atmospheric instability in southern Central America will generate a favorable environment for cloudiness and precipitation in different regions of the country.

The accelerated trade winds in the Caribbean Basin will facilitate the transport of moisture from the Caribbean, leading to morning and evening rains on Monday and Tuesday in the province of Limón and the Northern Zone. The intensity of the trade winds tends to decrease starting Wednesday, while precipitation decreases in these regions.

On the other hand, the Intertropical Convergence Zone is gradually approaching the southern part of the country, which, combined with warm morning temperatures, will create ideal conditions for showers and thunderstorms 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 Central Pacific on Monday and Tuesday. Cloud cover and occasional rain showers are expected in the Caribbean and the Northern Pacific 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 Pacific 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 Northern Pacific, 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 the Central Pacific and Guanacaste on Monday and Tuesday. In the Caribbean and the Northern Pacific, partly to completely cloudy conditions are expected with rain on Monday and Tuesday; partly cloudy from Wednesday onwards.
