Swell Summary
A series of North Pacific swells are due this week, likely leading to the first High Surf Warning event of the season starting on Tuesday. Energy from an approaching northwest swell will lead to above October average north shore surf into Monday. A storm force low, previously West Pacific Typhoon Bolaven, will send a large northwest swell toward the islands early next week. Small, long- period, westerly forerunners may arrive by Monday morning. The larger, long-period northwest swell will build rapidly from Monday into Tuesday, likely producing High Surf Warning conditions for north and west facing shores from Kauai through Maui from late Tuesday through Wednesday. This northwest swell will slowly decrease through the rest of the week.
Along south facing shores, a series of south-southwest swells will keep surf around October average through much of the week. Small surf heights continue along east facing shores through next Thursday.
