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 Thursday, a low-pressure system (a possible tropical cyclone) is forecast to track northeast of the Lesser Antilles, which will reduce wind speeds across the region, with generally southeasterly winds. In addition, depending on the strength of the low-pressure system, long period swells may be a concern toward the end of the upcoming week.

Seas Forecast For Trinidad and Tobago
Over the next seven days, winds are forecast to be generally from the south to east 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 25 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.
On Tuesday and Wednesday, winds are forecast to be light to near calm and variable as a result of a strong tropical wave moving across the Lesser Antilles while a possible tropical cyclone moving north of the Lesser Antilles, based on the latest model guidance.
Particularly from Tuesday, 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.
Through the next seven days, no significant long-period swells are expected, with swell periods forecast to remain between six and eleven seconds. However, king tides are expected through the forecast period.
Possible Impacts
Saharan Dust concentrations are forecast to increase from August 1st across T&T and 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 31st, 2023, through Thursday, August 3rd, 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.
Additionally, some of the highest high tides and lowest low tides for 2023 are forecast to begin from July 29th through August 4th, with peak King Tides from July 30th through August 3rd. Mariners will need to exercise caution, particularly during the high tide periods, and beachgoers will need to exercise caution due to an elevated rip current threat.
