Over the next seven days, 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 initially moderate seas, becoming slight, in Trinidad and Tobago’s open waters through the next seven days, with waves reaching between 1.0 and 1.5 meters, while in sheltered areas, waves remain smooth to near calm, generally below 0.5 meters.

Spring tides are forecast to continue through July 20th, with no significant long-period swells 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, particularly from July 19th, affecting visibility and air quality. Horizontal visibility will particularly be affected during dusk and dawn periods, where small craft operators should exercise caution.

Spring tides, which are higher than usual high tides and lower than usual low tides, are forecast to continue through July 20th, also requiring caution from all marine interests, particularly during high tide periods.

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.
