Low-level winds are forecast to remain anomalously low over the next five to seven days, resulting in near-calm seas in sheltered areas while seas in open waters remain slight, occasionally reaching moderate levels.
From late Monday through mid-Wednesday, a low-pressure system (either a strong tropical wave or possible tropical cyclone) is forecast to track across the southern Windwards, agitating seas in T&T’s marine areas.

Seas Forecast For Trinidad and Tobago
Over the next seven days, with the exception from late Monday through mid-Wednesday, winds are forecast to be generally from the east-southeast to east-northeast across Trinidad and Tobago, varying between 5 to 15 knots over the next seven days, with occasional gusts in isolated heavy showers or thunderstorms up to 20 knots.
The result is moderate to slight seas. In Trinidad and Tobago’s open waters through the next seven days, waves are forecast to reach between 1.0 and 1.5 meters, occasionally up to 2.0 meters, while in sheltered areas, waves remain smooth to near calm, generally below 0.5 meters and occasionally up to 1.0 meter.
On Tuesday, winds are forecast to be light to near calm and variable as a result of a strong tropical wave or possible tropical cyclone moving north of Trinidad and Tobago, based on the latest model guidance. On Monday night into the early hours of Tuesday, prevailing winds will be from the northeast, then near calm by daybreak, and then southerly to southeasterly through much of Tuesday. While open water conditions, particularly near Tobago and the north/east coastlines of Trinidad, are forecast to experience moderate to occasionally rough seas and sheltered areas along those coastlines have waves up to one meter, elsewhere will be near calm to smooth. Caution will be required for the northern Gulf of Paria as southerly winds will support northerly moving showers and thunderstorms, creating larger than usual waves along south-facing coasts of the Gulf of Paria on Tuesday.
Note: This forecast for late Monday through mid-Wednesday may change depending on the development and eventual track of Invest 95L, an area of low-pressure system being monitored for development east of the Lesser Antilles.
Through the next seven days, no spring tides or significant long-period swells are expected. Over the next seven days, swell periods are forecast to remain between six and eleven seconds.
Possible Impacts
Saharan Dust concentrations are forecast to remain at elevated levels and fluctuating levels through the forecast period. However, no significant impacts are forecast through the next seven days.
From late Monday, July 24th, 2023, through mid-Wednesday, July 26th, 2023, mariners will need to pay close attention to both marine and weather conditions due to an atypical wind regime that can produce potentially hazardous conditions in usually calm areas.
While no other significant hazards are forecast, it is always worth mentioning the rip current hazard that exists on all beaches across T&T, particularly northern and eastern-facing coastlines that receive the larger waves in sheltered areas.
