Weather in December

December is a transitional month in Puerto Rico that sees the reversal of the wet season. The average temperatures are in the 73°F (22.8°C) to 84°F (28.9°C) and see a gradual drop by the end of the month. Puerto Rico hardly has any winter cold due to its tropical location, and cold air from the poles does not travel till the tropics.
December still sees 20 wet days and 5" (127mm) of rain, but the cycle decisively shifts towards the dry season. The humidity drops significantly to make the atmosphere pleasant and warm. The daily sunshine is more than 7 hours, but the sun is more like a caring father than a scolding one. Thunderstorms and flash floods last till the end of the year, and an occasional storm still passes over the land.
Christmas and New Year's Eve sees many visitors in Puerto Rico due to its warm weather and budget-friendly vacations. The crowds begin to swell in Puerto Rico in December in anticipation of pleasant weather.
