Friday, May 16, 2025

This Friday, the country will experience the typical rainy season pattern. The Intertropical Convergence Zone, as well as local factors, will favor rainy activity primarily in the afternoon. This morning, partly cloudy conditions predominated in the central and northern parts of the country. Variable cloudiness was observed in both coastal areas of the country in the early morning hours, decreasing as the season progressed. During the afternoon and part of the evening, isolated showers with thunderstorms are expected for the Central and South Pacific, the Nicoya Peninsula, the surrounding areas of the Guanacaste and Tilarán mountain ranges, and the Central Valley. The Caribbean and Northern Zone maintain a chance of occasional rain in lowland areas due to cloud cover moving in from the sea, in addition to the possibility of localized showers with thunderstorms in mountainous areas.
