The Meteorological Institute predicts an intense rainy season in Costa Rica for 2022:


The National Institute of Meteorology (IMN) presented the forecast for the 2022 rainy season, noting that intense rainfall is expected, as well as at least 14 tropical cyclones (storms or hurricanes) throughout the year.

As part of a coordinated strategy, the National Institute of Meteorology has joined forces with the Ministry of the Environment and Energy (Minae) and the National Commission for Risk Prevention and Emergency (CNE) to present its forecasts and establish possible emergency scenarios.

Dry conditions in the northern area and the Caribbean will continue through May and are expected to change when the usual rains begin.

According to National Institute of Meteorology, 2022 will be marked by the ENSO phenomenon, or as it is commonly called and known in the country, the La Niña (The Girl) phenomenon. This condition will be maintained, at least, until the quarter from May to July.

Typically, Atlantic hurricane season runs from June 1 to November 30; although this does not mean that tropical cyclones or depressions cannot occur outside of these dates. This year is expected to be a “more intense than normal” season.

The head of the meteorology department, Eladio Solano, pointed out that between 11 and 14 named tropical cyclones (those that reach at least tropical storm category) are likely this year. Between 5 and 9 named tropical cyclones will reach hurricane status; and of these, 1 or 2 will reach the intense hurricane categories (categories 3, 4 or 5).

Typical conditions for Atlantic hurricane season consist of 7 named storms; 4 of them become hurricanes and 3 of them major hurricanes.

The rainy season is expected to begin before typical climatological dates; specifically, experts believe it will begin about a week earlier: in the South Pacific regions in late March, in the Central Pacific in late April; and in May for the rest of the regions: Central Valley, North Pacific and the area of ​​Guatuso, Los Chiles and Upala.

The peak of the rainy season is in September, October and November. Above normal rainfall conditions are expected in all regions of the Pacific and Central Valley, as well as in the northwest area (Guatuso, Los Chiles, Upala). Meteorologists claim that this is inferred from the current projection of the ENSO phenomenon and a potential influence of tropical cyclones on the territory.
