IMN Forecasts Up to 80% Rainfall Deficit in Guanacaste, Early End to Rainy Season

Costa Rica's meteorological institute (IMN) projects a severe rainfall deficit of up to 80% in Guanacaste and an early end to the rainy season due to El Niño, with high temperatures expected on the Pacific Slope in Q4. The forecast is based on seasonal models but actual impacts depend on El Niño intensity. This threatens agriculture, water supply, and hydropower in a key region.
