We are definitely feeling the effect of El Niño 2026! Here on the Caribbean foothills of Costa Rica, where the Guayacan Rainforest Reserve is located, during El Niño events such as the one we are currently experiencing, we expect to receive above average rainfall. It has been raining constantly for more than 24 hours, ranging in intensity from moderate to heavy downpour. As can be seen in the image of the digital rain gauge here at the Guayacan Rainforest Reserve, we have received 216 mm, 21.6 cm, or 8.5 inches of rainfall in the last 24 hours. Also visible in this image is the amount of rainfall that we have received Since January 1st 2026 (7.5 months), a total of 4,449 mm, 444.9 cm, 4.45 meters, 175.2 inches, or 14.6 feet! We are only half way through August, and we still have 4.5 months of time and additional rainfall accumulation to go in 2026. We might be on track to beat the record amount of rainfall we have recorded here in over 20 years, which was 7,822 mm, 782.2 cm, 78.2 meters, 307.8 inches, or 25.7 feet back in 2015, another El Niño year! The "normal" amount of rainfall that we expect to receive here per year is 5 to 6 meters or 16 to 20 feet.
