HIGH SURF WARNING FOR NORTH FACING SHORES

Swell Summary

The northwest swell that provided High Surf Advisory surf heights this morning will continue declining tonight. Surf across north and west facing shores will likely look fairly small Saturday morning before an XL NW swell builds rapidly in the afternoon through the evening. This swell is expected to bring surf heights up to 35 to 45 feet at most north and west facing shores with larger waves at select outer reefs. An altimeter pass from earlier today reflected swell numbers consistent with model predictions, boosting confidence in the forecasted surf numbers. This swell will peak Sunday morning, and slowly decline on Monday. A High Surf Warning is in place for the N and W facing shores of the smaller islands, with a another separate warning expected for the west facing shores of the Big Island. The reason for the separate warning is that the timing of the swell will be slightly later for the western Big Island. Another moderate to large NW swell is possible for the second half of next week from another potential Gale to Storm force low that is forecast to develop in the NW Pacific.

East shore surf will remain small through the weekend due to weak winds. Select south- facing shores could experience westerly wrap from this weekend's large northwest swell passage.
