The best time to visit Carenero Island is during the dry season, which generally runs from February to April and again from September to October.These months offer the most consistent sunshine and calmer seas, which are ideal for enjoying the island's activities. You can expect pleasant weather for swimming, snorkeling, and exploring the island's beaches. The reduced rainfall during these periods makes for a more comfortable and enjoyable experience overall.For those interested in water activities like surfing, the shoulder months just outside the peak dry season, such as November or May, can also be good.
