A High Surf Warning indicates that dangerous, battering waves will pound the shoreline. This will result in very dangerous swimming conditions, and deadly rip currents.

EFFECTS: Very large northwest swells will move down the island chain today, bringing warning level surf to north and west facing shores. Surf will peak on Kauai and Oahu this morning, on Maui this afternoon, and on the Big Island tonight. Warning level surf will last through tonight. Wave run-up and coastal erosion is possible along low-lying coastal areas.

Surf heights will be 25 to 35 feet along north facing shores and 15 to 25 feet along west facing shores.

Forecast surf heights are estimates of the height of the face or front of waves.

A high tide of approximately 1.3 feet is expected between 9:58 a.m. and 11:16 a.m. this morning. The next high tide of approximately 2.4 feet is expected between 1:16 a.m. and 2:34 a.m. tomorrow morning.

PRECAUTIONARY MEASURES: BEACH GOERS ARE URGED TO STAY OUT OF THE WATER AND WELL AWAY FROM THE SHORE BREAK DUE TO THE HAZARDOUS WAVE ACTION AND STRONG RIP CURRENTS.
