Tides: Heights displayed are relative to the Mean Lower Low Water (MLLW) datum in feet. Surf heights can vary significantly from beach to beach along a coastline. Surf larger than the upper end of the range provided in the forecast will occur periodically, sometimes up to a few hours apart. Expect to encounter rip currents in or near the surf zone, with rip current strength increasing with surf size. Swimmers are urged to exercise caution at all times and enter the water near a lifeguard.
