The average monthly weather in Barbados maintains one of the smallest temperature ranges throughout the year of any Caribbean destination.

This southeastern Caribbean island is a popular port of call for cruise ships because of its shopping, beaches and other attractions. It’s also popular because it is close to other ports of call in the region.

Predictable and steady temperatures make it an appealing destination during the winter, spring and summer. The climate is less appealing in the fall because of heavy rains during the Barbados rainy season.

When is the Barbados Rainy Season?

Barbados on average receives about two inches of rain each month from January through May during an annual dry season.

Late winter to early summer is an ideal time for a vacation or cruise to the island because of the low risk of rain and warmer temperatures.

Average rainfall increases to more than three inches in June and keeps increasing each month until it hits a high point of 6.5 inches in October and November during the height of the Caribbean hurricane season.

The island also receives nearly 6 inches of rain on average every August and September during hurricane season.

Hurricane season runs from June through November with the fall months experiencing the most rain and highest risk of either tropical storms or hurricanes.

Hurricanes rarely hit any island directly and instead pass nearby. Islands such as Barbados experience heavy rainfall and high winds for brief periods of time.

The June, July and December climate has moderate rainfall. June and July are offer warm temperatures to families on summer break from schools. December has lower temperatures but an escape from northern winters.
