Trinidad’s geographical location puts it on the southern periphery of the North Atlantic hurricane basin.Īs such, Trinidad is not affected directly by storms as frequent as Tobago however, peripheral weather associated with the passage of tropical storm systems impacts Trinidad and Tobago similarly. Within the wet season is the hurricane season which runs from June to November, peaking between August and October. Variations in these two climatic seasons between the islands of Trinidad and Tobago are primarily as a result of difference in land size, orography, elevation, orientation in terms of the trade winds and geographical location. The periods late May and December are considered as transitional periods to the wet and dry seasons respectively. Symbolizes the wet season during June to December. Maritime climate that is characterized by moderate to strong low level winds, warm days and cool nights, with rainfall mostly in the form of showers due to daytime convection.Ī modified moist equatorial climate characterized by low wind speeds, hot humid days and nights, a marked increase in rainfall which results mostly from migrating and latitudinal shifting equatorial weather systems, The dry season which occurs during January to May is symbolized by a tropical These seasons are differentiated by distinct dry and wet season regimes.

With the passage of this Tropical Wave, the ITCZ which is currently south of 10N, is expected to gradually migrate northward over the weekend, increasing the potential for showers and isolated thunderstorms across T&T. Across both islands, there is a medium chance (60%) of heavy showers and/or thunderstorms with accompanying gusty winds. ![]() As the day progresses, this TW will continue to affect T&T, with the most enhanced weather remaining over eastern offshore areas.
