The weather in Nicaragua is fantastic for most of the year. The “rainy season” coincides with the consistent wave season and is generally from May to October. A “rainy” day in that season may consist of 1-2 hours of rain in the afternoon, with sun and warm weather on either side. The rain is a welcome break from the heat most days. You can expect sunny days in the ’90s, and water temps in the ’80s. Unlike southern Nicaragua, where water temps often drop into the 70’s when the offshores are howling, requiring wetsuits, northern Nicaragua’s coast has temps between 80 and 84 degrees year-round.
