The climate of Puerto Rico
Puerto Rico has a tropical climate with very warm weather all year round with reasonably high precipitation figures, without a distinct dry period. Winters are slightly drier than the rest of the year. During the winter it is also colder and less muggy than during the summer. Puerto Rico is the most popular tourist destination in the Caribbean. The largest part of the tourists that travel to the Caribbean go to Puerto Rico. More than 75% of the tourists come from the United States of America. Puerto Rico is a popular stop-over and a popular starting point for cruise lines. Many cruise ships make a stop-over on this beautiful island. Officially the country is known as the Commonwealth of Puerto Rico; it is an unincorporated territory of the United States but is seen as an autonomous region in many ways.

Because the central part of Puerto Rico is a mountainous region with its highest point at an altitude of 1,338 meters, the island can be divided into two parts. The northern part of the island is slightly wetter. The southern and eastern part of the island are situated on the leeward side and are consequently protected from depressions. Because of this precipitation figures are lower along the south coast from December till April. In the southern part temperatures are 1-2 degrees lower on average than along the more popular north coast.

Summer in Puerto Rico
Summers in Puerto Rico (May-September) are slightly warmer than winters and chances of unstable weather are slightly higher. Chances of unstable weather are caused by a higher activity of depressions coming from the Atlantic Ocean. These depressions may be very active and cause heavy showers and fierce winds. In the worst case scenario a depression grows into a tropical storm or hurricane. There is a risk of hurricanes during ‘hurricane season’ which is from June till the beginning of December. However, if you travel to Puerto Rico during this period you should not worry too much about hurricanes. The chance of a hurricane hitting the part of the island where you stay is less than one tenth of a percent. Daytime temperatures during the summer are around 30 degrees Celsius (86.0 degrees Fahrenheit). During the night temperatures remain well above 20 degrees Celsius (68.0 degrees Fahrenheit) which is warm enough for a pleasant sunny holiday. During this period you do not even need a jacket, sweater or cardigan.

Winters in Puerto Rico are warm with temperatures around 30 degrees Celsius (86.0 degrees Fahrenheit). Minimum temperatures hardly ever drop below 18 degrees Celsius (64.4 degrees Fahrenheit). Because of this the climate of Puerto Rico can be classified as tropical. During the winter chances of precipitation are smaller than during the summer; chances of fierce winds are even much smaller. If you book a cruise that makes a stop-over in Puerto Rico during the winter you will not have to worry about it being cancelled or delayed because of bad weather.

UV-index figures are almost always high in Puerto Rico. With a maximum figure of 11 during a large part of the year we advise you to apply and re-apply sunscreen with a high protection factor.

Apart from hurricanes only few extremes in weather and climate can be recorded in Puerto Rico. Wintry weather such as snow, glazed frost or subzero temperatures are uncommon. Extremely hot weather with temperatures of 40 degrees Celsius (104.0 degrees Fahrenheit) or higher are uncommon as well. This is because of the tempering influence of both the wind and sea
