Don’t expect St. Thomas weather in October to deliver days of sunshine and clear skies. The odds are good that it won’t.

This crown jewel of the U.S. Virgin Islands is a hugely popular stop for eastern Caribbean cruises. It is especially popular because it has one of the largest duty-free shopping zones in the region.

But rainy October days will make shopping, sunning on the beach and taking part in various water sports quite a bit less fun.

The following St. Thomas climate averages are based on a 30-year history. Actual results will vary from one year to the next.

St. Thomas Rainfall in October

October is one of the worst months of the Caribbean hurricane season, which runs from June 1 through Nov. 30.

Tropical storm and hurricane activity usually peak for many destinations in either September, October or November.

In the case of St. Thomas, the rainfall is pretty much the same for all three months. The average rainfall for St. Thomas in October is nearly 5.5 inches, according to the U.S National Weather Service. The same is true for September and November.

By comparison, the island receives less than two inches of rain in January through March during the dry season.

Temperatures in October

The average high temperature for St. Thomas in October is 89 degrees Fahrenheit or nearly 32 Celsius, according to the U.S. National Weather Service. It is in line with most other months from spring through fall.

The average low temperature is about about 77 degrees Fahrenheit or 25 Celsius. The average low usually takes place at night.

Seawater is usually still comfortable for swimming throughout the fall.

Whether to Go

An average of 5.5 inches of rain in October is actually not as bad as quite a few other destinations during the month.

Some of them receive as much as 10 inches or more in October. But it’s obvious that most other months from December through August have much lower rainfall.

For anyone determined to take a vacation in the Caribbean in October, one of the best ways to go is via a last-minute vacation.

It is wise to look at weather charts for the eastern Atlantic to see what weather conditions are forming because it is there that storms and hurricanes usually have their start before moving to the Caribbean.
