Barbados weather is generally warm and sunny all year round with an average daytime high of 75 – 85 F. The nights are usually slightly cooler.
The prevailing northeast tradewinds blow steadily so that although it is bright and sunny, it is not unbearably hot.
The rain usually comes in quick showers. The dry season lasts from January to June.
We are in the tropics, and believe it or not, some people actually put on a sweater in the cool night winter time breezes. Barbadians complain that the sea is cold when it’s 78oF !!!
It rains most in summer and a good rainfall is refreshing and much needed. Rain is usually followed quickly by sunny skies and within minutes everything will be dry.
Tropical rainstorms sometimes occur in the hurricane season which runs from June to October (as we say in Barbados – “June too soon, October all over!”). Tropical rains are spectacular but the island is very porous and the heaviest rains quickly drain off into the underground lakes or the sea.
Hurricanes usually avoid Barbados. They arise off the African Coast and head to the Caribbean, swinging North about 100 miles from Barbados.
The pattern is reasonably consistent as hurricanes tend to bounce from one land mass to the next and Barbados is somewhat separate from the Caribbean island chain. This does not of course make us immune, but the last occasion which Barbados suffered a direct hit from a hurricane was in 1955. There is a story of a bus driver who drove his passengers straight through the worst of Barbados’ hurricanes, “was a bit of a breeze” he is supposed to have said.
Other major recorded hurricanes to hit the island occurred in 1898 and 1831.
