HIGH SURF WARNING FOR NORTH AND WEST FACING SHORES

Swell Summary

A large west-northwest swell (295-310 degrees) will build down the island chain through the evening and peak late tonight into early Saturday. High Surf Warning conditions will occur along exposed north and west facing shores of Niihau, Kauai, Oahu, and Molokai, as well as north facing shores of Maui into Saturday morning. The swell will reach west facing shores of the Big Island around sunrise, and a High Surf Advisory is in effect for that area through at least the afternoon. The swell will decline sharply Saturday afternoon and evening, with surf expected to fall below High Surf Advisory levels by Sunday morning. Small to moderate north-northwest swells will prevail through the remainder of the week.

Surf along east facing shores will remain very small into the evening. East shore surf will build and become rough from west to east late tonight and Saturday as the front moves down the island chain. Large and very rough seas will develop on Sunday as trade winds strengthen, likely exceeding the advisory level Sunday night or Monday and potentially reaching the warning level. Large east shore surf will slowly decline Tuesday through the remainder of the week. Surf along south facing shores will remain small with a slight bump possible early next week.
