Possible Impacts
No major marine impacts are forecast over the next seven days. However, mariners should exercise caution during periods of inclement weather, as seas may become locally rough or choppy in the vicinity of heavy showers and thunderstorms, particularly due to gusty winds.
Due to the Intertropical Convergence Zone remaining across the country this week, winds are forecast to be light to near calm and variable, with southeasterly to southerly winds possible on Tuesday through Friday. This may also lead to agitated seas in the Gulf of Paria and larger-than-usual waves along south-facing coastlines as heavy showers and thunderstorms move south to north.
Spring Tides, which are higher-than-usual high tides and lower-than-usual low tides, are forecast to begin on July 19th. All marine interests are advised to exercise caution, particularly during high tide periods.
Lastly, Saharan Dust levels are forecast to increase from July 20th, leading to increasingly hazy skies and marginally decreased horizontal visibility, particularly near dust and dawn.
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.
