Sea Forecast: Surge of Winds To Slightly Agitate Seas As King Tides Subside

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 Sunday into Monday briefly, increasing seas in our open waters but moderate seas are forecast through the 7-day-period.

In the next 24 hours, some of the highest hide tides and lowest low tides are forecast to subside. These tides are called King Tides, related to last Monday’s supermoon.

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, though ash venting has ceased for now.

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

Impacts on T&T’s Shorelines

No major impacts are forecast for T&T’s shorelines through the next 7 days. Due to King Tides, stronger tidal currents in nearshore areas; hence mariners will need to exercise extreme caution.

Minor coastal flooding is possible in low-lying coastal areas as peak high tides occur.
