While seas are not forecast to reach levels warranting a Hazardous Seas Alert from the Trinidad and Tobago Meteorological Service, caution is advised for beachgoers and all marine interests.

From Friday, September 8th, 2023, through Monday, September 11th, 2023, mariners will need to pay close attention to both marine and weather conditions due to an atypical wind regime that can produce potentially hazardous conditions in usually calm areas.
Mariners will need to exercise caution, particularly during the high tide periods, and beachgoers will need to exercise caution due to an elevated rip current threat as a result of higher-energy swells producing larger than usual waves along the north coasts of both islands.
