Swell Summary

Forerunners from a small, medium- period, northwest swell are still on track to arrive late tonight, with this swell forecast to build Tuesday and peak on Wednesday. This should bring an uptick in surf along north facing shores.

A moderate, medium- period north- northeast swell arrives on Tuesday and peaks also on Wednesday, bringing moderate surf to north and northeast facing shores, before slowly declining through the end of the week. East facing shores will see an increase in surf with wrap from the aforementioned north-northeasterly swell despite below- seasonal average to below average trades. Strengthening trades late this week will also give east facing shores a bump in surf.

Surf will continue to be small along south facing shores through the period.
