Over the next seven days, winds are forecast to generally be moderate, leading to moderate seas in open waters, with occasional peaks in sustained winds and gusts near showers and thunderstorms. Additionally, toward the end of the forecast period, long-period swells and spring tides are expected, leading to agitated seas in nearshore areas.

Seas Forecast For Trinidad and Tobago
Thursday into Friday: Seas are forecast to be generally moderate in open waters, with waves between 1.5 and 2.0 meters as winds range between 10 to 15 knots initially, nearing 20 knots (sustained by Thursday night into Friday morning) from the southeast to east, with gusts up to 30 knots in heavy showers and thunderstorms. In sheltered areas, waves are forecast to be generally below 1.0 meter, but with heavy showers/thunderstorms nearby producing stronger wind gusts, seas can become locally choppy/rough. Swell periods are forecast to remain 8 to 12 seconds, which may result in larger waves along eastern and northern coastal areas.
Saturday into Sunday: Seas are forecast to be slight to moderate in open waters with waves between 1.0 and 1.5 meters, while in sheltered areas, waves are forecast to be below 1.0 meters to near calm. However, with forecast afternoon heavy showers/thunderstorms, nearshore areas could become agitated. Swell periods are forecast to range between 7 and 11 seconds. Winds are forecast to range between 10 to 15 knots from southeast to east, gusting up to 20 knots near showers or thunderstorms.
Monday through Wednesday: Seas are forecast to be slight to moderate in open waters with waves between 1.0 meters and 2.0 meters, while in sheltered areas, waves are forecast to be below 1.0 meter. However, swell periods are forecast to increase, ranging between 12 and 17 seconds. These long-period swells will create hazardous conditions along nearshore coastal areas of both Trinidad and Tobago, particularly northern and eastern areas, on Monday into Tuesday morning and by Tuesday afternoon along western coasts. Winds are forecast to range between 10 to 15 knots from southeast to east, gusting up to 20 knots near showers or thunderstorms.
Possible Impacts
Saharan Dust concentrations are forecast to increase from late October 6th, 2023, leading to a marginal reduction in visibility through the upcoming weekend.
Longer period swells are explicitly forecast from Monday, which will result in larger than usual waves along the northern coastlines of both islands initially, then affecting western coastal areas by Tuesday. Mariners and beachgoers should follow advice from lifeguards and exercise caution. This long-period swell event is forecast to continue through the end of next week.
Spring tides, which mean higher than usual high tides and lower than usual low tides, are forecast to begin by Wednesday, October 11th, 2023. Combined with the forecast long-period swell event, spring tides may create potentially hazardous conditions for marine interests during peak high tide periods.
With both of these hazards present through the forecast period, rip currents also pose a threat, particularly on the northern and eastern beaches of both islands.
