Weather forecast

Tuesday, April 22, 2025

This Tuesday, the influence of a high-pressure system north of the Caribbean Sea basin persists, causing an acceleration of the trade winds. At the same time, there is an increase in atmospheric instability and higher moisture content over southern Central America. These factors favor variable cloudiness ranging from partial to total, and scattered rainfall in the Caribbean and Northern Zone, especially between the early morning and morning hours. In the afternoon, rain is expected in the mountains, and precipitation cannot be ruled out during the nighttime period. These conditions may also occur in the eastern and northern parts of the Central Valley, with occasional drizzle. In the Central and Southern Pacific regions, partial cloudiness is expected during the first half of the day. Additionally, showers with a chance of thunderstorms are forecast for the afternoon and early night. Rain is also possible in the southeastern part of the North Pacific and on the Nicoya Peninsula. Furthermore, moderate to strong wind gusts are expected in the North Pacific, Central Valley, and mountainous areas of the country.
