Swell Summary

The current northwest swell continues to decline through today. A much larger north swell will build overnight into Thanksgiving Day. The peak of this swell may approach warning levels along north facing shores. It will also coincide with gusty northeast winds and the spring high tide during the early morning hours Thursday and Friday. Adding the potential for gale force winds along the cold front, there could be significant overwash issues and large wave run up along north facing shorelines. Areas exposed to north swells on other shorelines should see a significant rise in surf as the north swell moves in. Strong low pressure to our north northeast, will send a strong north northeast swell that should keep large, short to moderate period swell over the islands. There is a potential for significant harbor surges for Kahului, and Hilo starting Thursday through the weekend associated with both large swells.

Surf along east facing shores will decline as the trade winds slack slightly today with a slight boost Thursday as trade winds ramp back up. South facing shores will see minimal energy for the foreseeable future.
