Swell Summary

A mix of small pulses of south- southwest swells is still anticipated for tonight through Friday, recharging near average surf along south facing shores.

Long-period energy from a storm that passed within our swell window around New Zealand earlier this week is peaking at the Samoa Buoy this afternoon at around 15 feet 20 seconds. Surf heights are expected to gradually build locally Saturday and peak Sunday into Monday before slowly declining through the first half of next week. This swell will also coincide with the peak monthly tides and will lead to significant wave runup and minor coastal flooding during the first half of next week, particularly during the peak daily high tide cycles. A marine weather statement is also anticipated due to the threat of harbor surges. South shore surf will remain elevated through much of next week due to the slow decline of this large south swell and a series of more overlapping southerly swells.

East shore surf will slowly decline below seasonal averages through the the weekend as trades ease, then pick up a notch next week as more breezy trades return. No significant swells expected elsewhere.
