Climate of US Virgin Islands

Climate of US Virgin Islands

The US Virgin Islands are part of the Virgin Islands and have been a Danish colony for many years, until Denmark sold these islands located in the Caribbean to the United States of America(in 1917). In the distant past, the islands were also Dutch property for a while. The United States Virgin Islands (US Virgin Islands) have an Aw climate or a tropical savanna climate within the Köppen-Geiger climate classification. The average maximum temperatures in the Virgin Islands have little variation: on average during the hottest hours of the day it is about 29 to 33 degrees. Thanks to the trade wind, which is almost always present, and the seawater (which has an average temperature of 26 to 29 degrees), the temperatures remain moderate and will rarely exceed 34 to 35 degrees Celsius.


The US Virgin Islands have a drier season that starts at the end of December and lasts until the beginning of August. The month of May is usually slightly wetter within this season, while the months of February and March are the driest, with an average of less than forty millimeters per month. The wet season starts in mid-August, during which – due to the still relatively modest amounts for this region – there is actually no real rainy season. You do notice that the number of showers is increasing and especially that there are several showers in a day, while in the dry season the rain is often limited to one shower per day. The total annual precipitation amounts to an average of 960 millimetres, with the wettest places in the US Virgin Islands registering about 300-400 millimeters more annually and the driest places can write about eight hundred millimeters per year in the books. It is simply too hot for snow in the US Virgin Islands.


During the day, the mercury reaches values ​​between 30 and 33 degrees almost every day. Sometimes you have to deal with an outlier to 34-35 degrees, but in December, January and February that chance is very small. The minimum temperatures are between 22 and 26 degrees, with an occasional spike downwards. The lowest recorded temperature in the US Virgin Islands is 11.1 degrees Celsius, the highest official temperature recorded is 37.2 degrees.


The United States Virgin Islands are under the influence of the northeast trade for most of the time. Some years this trade wind turns slightly and comes mainly from the east or south east. The eastern parts of the US Virgin Islands are almost always in the wind, while the west is more in the lee. During the hurricane season (July to December) there is an increased chance of tropical depressions and tropical storms. Sometimes a tropical depression grows into a hurricane with devastating wind speeds. A hurricane in the vicinity can also cause tidal waves that can cause a lot of damage along the coasts of the US Virgin Islands. There is therefore always a chance that the cruise boats will have to adjust their schedule during the hurricane season due to tropical storms. Because the US Virgin Islands is a frequently used destination of various cruise lines, there is a chance that hurricanes will divert to the US Virgin Islands elsewhere, or that there will be an extra day in port. Anderson, it is also possible to avoid the Virgin Islands due to a local tropical storm.
