Throughout this upcoming week, periodic showers and thunderstorms are set to create occasionally choppy conditions across T&T’s marine areas, warranting caution from mariners.
What you need to know
— What: Occasionally choppy seas as a result of wind gusts and elevated winds accompanying showers and isolated thunderstorm activity, with possible mid-week long-period swells affecting northern coastlines.
— Where: Choppy seas are likely across the entire marine area, open waters, and sheltered areas, where showers or thunderstorms occur. Impacts from occasional mid-week long-period swells are likely to remain isolated to north-facing coastlines of northern Trinidad and Tobago.
— When: Agitated seas are likely from today (Sunday) through Wednesday due to forecast showers and isolated thunderstorms, with long-period swells affecting northern coastlines mainly on Wednesday through Thursday.
— Impacts: Large open water waves may be hazardous to smaller marine vessels, making operations difficult with large waves. Larger waves along northern and eastern coastlines may lead to beach erosion. Elevated threat of rip currents on northern and eastern coastlines.
— What Should You Do: All marine interests need to exercise extreme caution, while small craft operators should seek safe harbor when heavy showers or thunderstorms are nearby. Inexperienced mariners should avoid navigating in hazardous conditions, especially those operating smaller vessels. Inexperienced swimmers should remain out of the water due to unsafe surf conditions. If you intend to go into the water, it is recommended that you use beaches with on-duty lifeguards. Secure objects on the beachfront that the wave action or winds may sweep away.

Seas Forecast For Trinidad and Tobago
Winds are forecast to remain from the east to south between 10 and 20 knots, with gusts to 25 knots. Seas in open waters are forecast to remain moderate, with waves between 2.0 and 2.5 meters through Monday, coming down to maximum heights of 2.0 meters through Saturday.
Waves in sheltered areas of both islands remain near 1.0 meters through the forecast period. Seas may become locally choppy or rough in showers and thunderstorms. Swell periods are forecast between 8 and 12 seconds, with swells from mainly the north and northeast. Between Wednesday and Thursday, these swell periods may range between 8 and 15 seconds, requiring all marine interests to exercise caution, particularly along northern and northeastern coastlines.
What should you do
All marine interests need to exercise extreme caution, while small craft operators should seek safe harbors. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions.
On Wednesday and Thursday, occasional long-period swells are forecast to bring occasional battering waves along the northern exposed coastlines of both islands. Marine interests should also exercise caution.
With elevated winds in showers or thunderstorms forecast, secure objects on the beachfront that the wave action or winds may sweep away.
Inexperienced swimmers should stay out of the water during heavy showers or thunderstorms due to likely unsafe surf conditions. If they intend to go into the water, it is recommended that they use beaches with on-duty lifeguards.
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.
