Scientists have confirmed what many who have witnessed recent gray skies and showers may have already suspected – the transition from the dry season to the rainy season is now under way.

During the next week, cloudy skies and isolated showers are expected around the country, weather “typical to the month of April,” National Meteorological Institute (IMN) forecaster Gustavo Murillo told the daily La Nación.

These isolated showers have already begun in the Central Valley provinces of Alajuela, Heredia, Cartago and San José, he said.

The transition from dry to rainy weather occurs when winds entering from the northeast Caribbean coast lose some of their strength and allow nuclei of clouds from the Pacific to come in, creating more humidity and clouds in the Central Valley, he said.

During the month of April, Costa Rican residents can expect sunny mornings and afternoon showers, but generally, the weather will be unpredictable.
