Seas Forecast For Trinidad and Tobago
From Wednesday, winds are set to increase, with sustained winds as high as 20 knots and gusts to 30 knots, peaking overnight Wednesday into Thursday. As a result, seas in open waters are forecast to be moderate, with waves up to 2.5 meters, while in sheltered areas, waves are forecast to remain below 1.0 meters. In heavy showers or thunderstorms, seas may become locally rough or choppy.
Conditions are forecast to improve by Saturday with sustained winds returning near 10 to 15 knots, with occasional gusts in heavy showers or thunderstorms nearing 20 knots. Seas in open waters are forecast to still remain moderate, becoming slight to moderate by Monday as winds further decrease.
However, from June 15th, 2023, spring tides are set to begin, with Saharan Dust concentrations increasing.
Through next week, swell periods are forecast between six and eleven seconds.
Possible Impacts
Saharan Dust concentrations are forecast to increase from June 14th, 2023, affecting both visibility and air quality.
With elevated low-level winds, mariners will need to exercise caution, particularly during dusk and dawn, where whipped-up sea spray may reduce visibility.
Additionally, spring tides are forecast to begin on June 15th, 2023 and continue through June 21st. These are higher than usual high tides and lower than usual low tides, combined with the presence of higher energy waves due to long-period swells, which will increase the rip current threat, particularly long eastern and northern coastlines. Rip currents are strong currents perpendicular to the shoreline that can carry even the strongest swimmers out to sea.
