Weekly outlook
From 10th to 16th April, 2025
General Review
During the next seven days, an increase in atmospheric instability is expected over southern Central America, due to the influence of various synoptic and dynamic factors. One of the main contributors will be the strengthening of Cold Surge #19, which will promote stronger winds and increased moisture transport toward the Caribbean and the Northern Zone.
As a result, variable cloudiness ranging from partial to overcast skies and rainy conditions are forecast for the Caribbean and Northern Zone, with possible intermittent rain and showers between the night of Saturday, April 12th and the morning of Monday, April 14th. The highest probability of rainfall will occur during the mornings and nights, while in the afternoons it is expected to decrease. Some of this cloudiness and rain may reach areas in the east and northern mountains of the Central Valley, as well as mountainous areas in the eastern part of the North Pacific.
In the Central Valley, mountainous regions, and especially in the province of Guanacaste, moderate to strong wind gusts are anticipated. Wind speeds will range between 40 to 75 km/h in the Central Valley and mountains, and between 80 to 100 km/h in the North Pacific. These winds, along with persistent cloudiness, will contribute to a decrease in maximum temperatures between Saturday and Monday, creating a cooler environment and even a sensation of cold in mountainous areas and the northern part of the country.
On the other hand, the possibility of scattered showers and downpours remains during the afternoons in the Central and Southern Pacific regions, with occasional rainfall during the early night hours.
