While no hazardous marine events are forecast over the next seven days, marine interests, particularly small craft operators, will need to exercise caution during heavy showers and thunderstorms due to occasional choppy seas. Periodic moderate to high-concentration Saharan Dust surges are forecast over the next week.

Seas Forecast For Trinidad and Tobago
Through Friday: Winds are forecast to notably increase across T&T due to the presence of a tropical wave over the area. As a result, seas are forecast to be moderate in open waters, with waves up to 2.0 meters. In sheltered areas, waves are forecast to be near 1 meter, but conditions may become locally rough and/or choppy in the vicinity of heavy showers or thunderstorms. On Thursday, winds are forecast to range between 10 knots and 20 knots from east to east-southeast, gusting to 30 knots. By Thursday afternoon through Friday, winds are forecast to decrease between 10 knots and 15 knots, from the east to southeast, gusting to 20 knots, mainly in the vicinity of showers or thunderstorms. Swell periods are forecast to range between 7 and 10 seconds. Saharan Dust concentrations will increase, reducing horizontal visibility, particularly by dusk on Thursday.
Saturday through Sunday: Seas are forecast to be slight to moderate in open waters, with waves up to 1.5 meters. In sheltered areas, waves are forecast to be below 1 meter. Swell periods are forecast to range between 7 and 10 seconds. Winds are forecast to be between 5 knots and 15 knots from east to southeast, with gusts up to 20 knots. A moderate but decreasing concentration of Saharan Dust is forecast to be present, reducing horizontal visibility.
Monday through Wednesday: Seas are forecast to be slight to moderate in open waters, with waves up to 1.5 meters. In sheltered areas, waves are forecast to be below 1.0 meter. Swell periods are forecast to range between 6 and 9 seconds. Winds are forecast to range between 5 and 15 knots from the east-southeast to southeast, gusting to 25 knots. Moderate to high Saharan Dust concentrations are forecast to be present, still reducing horizontal visibility, particularly at dawn and dusk.
Possible Impacts
Through the forecast period, small craft operators particularly will need to exercise caution due to reduced visibility as Saharan Dust concentrations increase.
Rip currents always pose a hazard on the nation’s beaches. If caught in a rip current, swim perpendicular to the current (parallel to the shore). Mariners, especially small craft operators, should ensure their vessels are securely anchored or docked, as choppy/breaking wave conditions may drag the vessel onto the ocean floor or reefs in shallow waters or even break anchorage/mooring.
