Tropical Climate of San Juan

Understanding the maritime tropical climate of San Juan

San Juan enjoys a maritime tropical climate influenced by trade winds and the Atlantic Ocean. The urban heat island effect amplifies temperatures in the historic center, while the proximity to the ocean moderates climatic extremes.

Historic Center: Warmer urban microclimate, with cobblestone streets that retain heat
Atlantic Coast: The most ventilated area with refreshing sea breezes
Modern Districts: Moderate temperatures thanks to green spaces and contemporary urban planning
