Puerto Rico Weather and Climate

Geographical location

According to abbreviationfinder, Puerto Rico is an instel state in the Caribbean, which in addition to the main island of Puerto Rico also consists of several small secondary islands and the so-called Spanish Virgin Islands.

Puerto Rico is a so-called non-incorporated outer territory of the USA, so it does not form a separate state and is not part of any other US state. However, the residents who call themselves Boricua are American citizens and all foreign policy is carried out by the Washington government.

The Caribbean island of Puerto Rico is one of the Greater Antilles and lies between Hispaniola (Dominican Republic and Haiti) and the British Virgin Islands.

The relief of the island is quite hilly, the mountain Cerro La Punta is the highest point with 1338 meters. The Rio de la Plata is the longest river in Puerto Rico with 97 kilometers.

Around 3.8 million people live in an area of ​​8959 square kilometers. The capital, San Juan, is located on the north coast and, as a metropolitan region, is home to around 2.5 million inhabitants.

From Germany, San Juan can be reached from Frankfurt in around 10 hours.

Climate in Puerto Rico

Puerto Rico has a tropical climate, with the south of the island state in particular remaining very dry. The maximum temperatures are around 32 degrees in the months of June to October. From November to May, temperatures can drop to 28 ° C. At night the values ​​reach between 21 and 25 degrees, so it remains very warm all year round. In the high altitudes of the island it is usually around 4 to 5 degrees cooler.

It can rain all year round in Puerto Rico. From a meteorological point of view, there is no classic rainy season (months with more than 175 mm), but the period from April is called until November as a wet period and colloquially it can be called a rainy season. Especially in the north, including in the capital San Juan, there is sometimes heavy rainfall during this travel time.

Puerto Rico is in the potential hurricane risk area, with around twenty hurricanes actually crossing the island in the last 150 years. The greatest risk is in August and September, officially the hurricane season lasts from early June to November.

When to go to Puerto Rico

Puerto Rico can basically be traveled all year round. Due to the risk of hurricanes mentioned and the increased rainfall, the “rainy season” from April to November is not necessarily the best time to travel to the region. The temperatures are now sometimes unbearably hot, as the high humidity can create an unpleasant sultriness.

You are much better advised in the drier months, even if the best travel time from December to April is the absolute peak season in the Caribbean and many hotels are booked months in advance. The months May to August are particularly popular with surfers due to the high waves. For a beach holiday or cruises, however, the months after the end of the hurricane season are more suitable.
