Beware of Pressure Waves when Crossing Bars

Crossing coastal bars always requires caution, but accidents often happen on days you think are safe, when the swell is small and the bar looks really easy to cross.

One of the reasons for this is the tide factor. On big ebbing tides, the extra volume of water running out through narrow bar openings creates pressure as it hits the incoming swells.

This pressure can cause waves to almost double in size and break unpredictably in places they wouldn’t normally break.
