Swell Summary

Strengthening trade winds will produce increasing, short period seas over the next few days. The combination of rough trade wind swell and a short period north-northeast swell will produce elevated surf along exposed north and east facing shores and may lead to a High Surf Advisory for some east facing shores late Monday through Thursday. A decrease in wind waves and the north-northeast swell is expected around Friday.

Small pulses of northwest swell are possible today and again Thursday and Friday, though resulting surf will be well below seasonal average. No significant swells are due for south shores.
