Two separate wet seasons shape the year here, roughly around May and September, with drier, more reliable stretches in between rather than one long wet or dry season. In January, expect highs around 30°C with rain on roughly 5 days of the month.
Old San Juan's colorful colonial streets and Spanish fortresses (El Morro, San Cristóbal) anchor a walkable historic core, and the bioluminescent bays — Mosquito Bay on Vieques is the brightest in the world — are worth a nighttime kayak trip. El Yunque, the only tropical rainforest in the US National Forest system, is an easy day trip from San Juan for waterfalls and hiking.
Try mofongo and lechón, Puerto Rican staples.
