Rain on Trinidad

Due to its location as the island furthest southwest in the Caribbean, Trinidad is right in the path of the Inter-Tropical Convergence Zone and is more susceptible to tropical waves.  What does this mean for the island?  They take their rainy season very seriously because it can be more damaging than others in the region.

This is important for potential visitors to be aware of, because visiting during the rainy season is not recommended.  Although advances in the world of meteorology provide fair warning when a tropical storm or hurricane is in danger of striking, rain can come on suddenly and strongly and drive people indoors for anywhere from several hours to several days.

Of course, locals don't live under a dark cloud between June and November.  For the most part, mornings are sunny with rain in the afternoon, and when the clouds clear, the nights are cool and comfortable rather than muggy.  It doesn't rain every day either.  During the rainy season, there can be several days in a row of sun, which locals call  Petit Carême.  This is similar to an Indian Summer, and usually occurs between mid-September and mid-October.  If there are so many potential sunny days, why is the island to be avoided during the rainy season?  Simply because the rain is so unpredictable and few tourists want to take the chance of planning a getaway that could be thrown off track so easily.

If you insist on visiting during this time, either because you have to, or perhaps to take advantage of low travel costs, know that the northern and eastern regions of Trinidad are known to get more rainfall, so if you can plan to stay to the southwest you'll have a greater chance of avoiding torrential downpours.  Carry a light-weight umbrella with you as a precaution, but if the winds pick up you'll be better off heading indoors.
