The climate in Puerto Rico

Climate zone: tropics

The climate in Puerto Rico is very warm, with an annual average of 30 degrees, but has few truly tropical and sticky months. It is warm to hot all year round, inviting bathing at average water temperatures of 28 degrees. Due to less rain, the best time for traveling is from February to March.

Long-term development of temperatures from 1997 - 2022

In contrast to single record values, long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. An average value would give a distorted result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and distorts the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have comparable data over as long a period as possible.

In the years 1997 to 2022, there were only these 1 weather stations in the whole country, which reported continuous temperature values (San Juan). From these weather reports, we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was June 2012 at 29.8 °C. February 1997 was the coldest month with an average temperature of 23.9 °C.

The average annual temperature was about 26.9 °C in the years after 1997 and about 27.5 °C in the last years before 2022. It has therefore increased only slightly by about 0.6 °C over the past 26 years. This trend only applies to the selected 1 weather stations in Puerto Rico. A considerably more comprehensive evaluation of global warming has been provided separately.
