Climate zones, seasonal temperatures, rainfall patterns, and best travel times
Puerto Rico has a warm tropical maritime climate shaped by trade winds, altitude, and strong regional rainfall contrasts. Coastal areas are hot year-round, while the central mountains are noticeably cooler and wetter. Most lowland locations fit tropical rainforest or tropical monsoon patterns, with some drier southern and western coastal areas approaching tropical savanna conditions. For residents and expats, the main climate considerations are heat, humidity, hurricane risk, and the big difference between coastal and mountain living.
