Swell Summary

Surf along east facing shores will quickly rise this evening, peak late tonight into Wednesday as Tropical Storm Calvin approaches and moves over or near the Big Island. Surf heights are expected to briefly reach warning level heights for east facing shores of the Big Island and Maui County tonight through Wednesday morning. A downward trend is anticipated through the second half of the week as Calvin continues to move far west and dissipates. For Oahu and Kauai, east shore surf heights will likely reach advisory levels Wednesday. Otherwise, no significant swells are expected through the weekend.
