The climate of U.S. Virgin Islands
The United States Virgin Islands are part of the Virgin Islands and were a Danish colony for decades until Denmark sold the islands to the United States of America. A long time ago the islands were a Dutch colony. The United States Virgin Islands have a tropical savannah climate type Aw according to the Köppen-Geiger climate classification. The average maximum temperatures show little variation. During the warmest time of the day temperatures are around 29-33 degrees Celsius on average. An ever present trade wind combined with the warm sea water (26-29 degrees Celsius on average) is responsible for moderated temperatures. Temperatures above 35 degrees Celsius are uncommon.

The US Virgin Islands have a dry season that lasts from the end of December till Early August. Within this season the month of May is a little wetter. The months of February and March are the driest with less than 40 millimeters of rain on average per month. In mid-August the wet period starts. However, precipitation figures are still low so ‘wet season’ is not really the correct term. Multiple showers per day are not uncommon, during the dry season this is mainly limited to one shower per day. About 960 millimeters of rain falls on average on a yearly basis. However, the wettest areas on the US Virgin Islands get about 300-400 millimeters more rain. The driest periods can record about 800 millimeters of rain. The US Virgin Islands are too warm for snow.

During the day temperatures are between 30 and 33 degrees Celsius. A peak in temperature of 34-35 degrees Celsius is not uncommon. Chances of very warm weather are smallest in December, January and February. Minimum temperatures are between 22 and 26 degrees Celsius with the occasional low. The lowest temperature on record for the US Virgin Islands is 11.1 degrees Celsius. The highest temperature for the US Virgin Islands is 37.2 degrees Celsius.

The US Virgin Islands are mostly influenced by a north east trade wind. During some of the years the trade wind comes from the east or the south east. The trade wind is ever present on the eastern part of the islands. The western parts are more on the lee-side. Sometimes a tropical storm forms from a tropical depression with destructive wind speeds. A hurricane in the vicinity may cause tidal waves that can cause major destruction along the coastline. There is an ever present chance that cruise ships have to change their schedule because of hurricanes. The US Virgin Islands are visited a lot by cruise ships. Because of bad weather they might be forced to sail to another port on the US Virgin Islands. It can also happen that they are forced to be anchored for a day longer. On the other hand it is also possible that they avoid the US Virgin Islands altogether because of hurricanes.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The information below is an average for the capital of Charlotte Amelie. Climate information on specific places and regions is shown on the pages per place.
