January is usually the coldest month of the year in Puerto Rico, with the average temperatures in the warm 72°F (22.2°C) to 83°F (28.3°C) range. San Juan, the capital, is busy with tourists from all over the world, crowding the place during the New Year. Day temperatures are comfortable, while nights are pleasant, with a drop in humidity. The bright sunshine lasts for 8 hours and bearable even during peak hours. The precipitation averages up to 3.8" (97mm) but is generally light, and the showers are brief. Seawater temperatures of 79°F (26.1°C) are warm enough for swimming. Visibility extends for several miles on the sea as the skies remain mostly clear at the end of the hurricane season. Light sea breezes prevail on the coast during the evenings that make beach visits pleasant. Light and bright clothes are preferable, and winter wear is generally dispensable in Puerto Rico in January.
