Climate of Puerto Rico - wikipedia Climate of Puerto Rico Moisture regimes of Puerto Rico Köppen climate types of Puerto Rico The climate of Puerto Rico in the Köppen climate classification is predominately tropical rainforest. Temperatures throughout the year are warm to hot, averaging near 85 ° F ( 29 ° C ) in lower elevations and 70 ° F ( 21 ° C ) in the mountains. Easterly trade winds pass across the island year round while the rainy season stretches from April into November. The relatively cool trade winds are blocked by the mountains of the Cordillera Central which causes rain shadows and sharp variations in the temperature and wind speed over short distances. About a quarter of the average annual rainfall for Puerto Rico occurs during tropical cyclones, which are more frequent during La Niña years.

The temperature in the south is a few degrees higher than the north. Between winter and summer, there is only a temperature swing of around 6 ° F ( 3.3 ° C ). Coastal water temperatures average between 77 ° F in February to 87 ° F in August. The highest temperature ever recorded was 103 ° F ( 39 ° C ) at San Lorenzo, while the lowest temperature ever recorded was 38 ° F ( 3 ° C ) at Aibonito. Climate data for Adjuntas Substation.

When the trades winds are lighter, sea breeze and land breeze circulations dominate. Every five years or so a hurricane brings high intensity wind. Rainfall There is a pronounced rainy season from April to November. Due to the island 's topography, rainfall varies greatly across the island. Pico del Este averages 171.09 inches ( 4,346 mm ) of rainfall yearly while Magueyes Island averages only 29.32 inches ( 745 mm ) a year.

On average, a quarter of its annual rainfall is contributed from tropical cyclones, which is more prevalent during periods of La Niña than El Niño. A cyclone of tropical storm strength passes near Puerto Rico, on average, every 5 years. A hurricane passes in the vicinity of the island, on average, every 11 years. Only one Category 5 hurricane has struck the island since 1851, the Lake Okeechobee Hurricane of September 1928. Sometimes waterspouts form off the coast during showers and thunderstorms, particularly off the west coast, with tornadoes and hailstorms possible in the inner sea. These thunderstorms may be formed due to tropical waves, tropical cyclones, and frontal boundaries which become stationary across the region between fall and spring. Weather by season The Wet Season begins in May and lasts to late October. The weather is hot and humid with thunderstorms in the afternoon, especially in August and September. Trade winds bring cool summer breezes in the north and east of Puerto Rico, but due to the topography of the island, these winds do not reach the coast south and west, causing much higher temperatures than in the north. During humid summer days, the heat index can reach 115 ° F ( 47 ° C ) and actual temperatures can reach 100 ° F ( 38 ° C ). Sometimes the wind shifts from the south, causing an inverse pattern, where the heat south of the island moves to the north, causing temperatures in the mid 90s ( 35 ° C ) in San Juan and low humidity. The month of June is usually the driest month of the summer. During June and July the precipitation is mostly caused by the effects of humidity and heat of the island. The peak of the hurricane season comes in September. Weather conditions can be very rainy as tropical lows pass near the island, with frequent strong thunderstorms. By early November the tropical cyclone season fades and the weather becomes drier and generally sunny. Late November brings the Dry Season which lasts through late April. Weakening cool fronts from the north lower temperatures and humidity, and dry and sunny conditions prevail. In San Juan in the winter months, high temperatures reach 77 -- 87 ° F ( 25 -- 30 ° C ) with an average high of 83 ° F and lows down to 66 -- 76 ° F ( 19 -- 24 ° C ), giving an average of 71 ° F ( 22 ° C ). In the central area of the island the elevation and reduced sea effects bring the minimum temperatures to 55 -- 65 ° F ( 13 -- 18 ° C ) on average. After fronts pass the temperature may drop to the 40s ( 4 -- 9 ° C ) in the mountains, in the 50s ( 10 -- 15 ° C ) in the valleys, and in the low 60s ( 16 ° C to 20 ° C ) in the coastal zone. In general the climate in the dry season is sunny, with little change from day to day. February and March are often quite dry, sunny and hot. Sun The sunrise varies from 5 : 30 a.m. in summer and 7 : 00 a.m. in winter. Sunset varies between 5 : 40 p.m. in winter and 7 : 10 p.m. in summer. Puerto Rico does not use daylight saving time. The ultraviolet index or UV index varies from 10 + in the summer and a maximum of 7 in winter.
