Moderate Seas Forecast For T&T, King Tides Arrive Next Week

Over the next seven days, the sea forecast to be quite normal for this time of year with no abnormal waves or swells forecast for the region. Low-level winds may increase on Tuesday briefly, increasing seas in our open waters but moderate seas are forecast through the 7-day-period.

Over the upcoming weekend into next week, some of the highest hide tides and lowest low tides are forecast to begin. These tides are called King Tides, related to next Monday’s supermoon. These tidal impacts are mainly expected next week.

Lastly, visibility may be slightly reduced due to fluctuating concentrations of Saharan Dust through the forecast period. We continue to monitor the ongoing eruption of the La Soufrière Volcano, which could send more volcanic ash across the Windwards, reducing visibility. At this time, no ash is forecast to impact T&T’s marine area.

There are no alerts, watches, or warnings in effect for T&T from the Trinidad and Tobago Meteorological Service concerning seas at this time,

No major long-period swells are forecast, but elevated swell periods may occur between Tuesday through Thursday, with swell periods between 9-14 seconds. Throughout the week, large, breaking waves may exceed the 1-meter mark along Northern and Eastern coastlines, up to 2.0 meters in nearshore areas. Generally, through the forecast period, swells are forecast to remain between 6-10 seconds from the north to northeast.

Winds are forecast to be fresh, with winds up to 20 knots from the east to northeast gusting up to 25 knots, particularly on Tuesday. Wind speeds are forecast to remain between 10 knots to 20 knots outside of this period, generally gusting to 25 knots.

Note that King Tides will cause some of the highest hide tide and lowest low tide levels for the year. These tidal currents will require caution from mariners due to strong currents. Beaches remain closed due to COVID-19 restrictions in T&T.

Impacts on T&T’s Shorelines

No major impacts are forecast for T&T’s shorelines through the next 7 days. However, as we head into the weekend and next week, our tidal range will increase due to King Tides. This will result in stronger tidal currents in nearshore areas; hence mariners will need to exercise extreme caution.

By next week, minor coastal flooding will be possible in low-lying coastal areas as peak high tides occur.
