Swell Summary
A small southeast swell and background swell energy from the south-southwest should maintain small surf along exposed south facing shores today. Modest, choppy surf will persist along east facing shores this weekend due to the trade winds. An upward trend in surf is expected along east facing shores early this week due to the arrival of a medium-period easterly swell, which is being generated by the captured fetch associated with Tropical Storm Calvin. Based on the latest track and intensity, surf heights along east facing shores will reach the High Surf Advisory threshold for most islands starting from Tuesday night into Wednesday. Confidence is building for a brief period of warning level surf within a similar time period along east facing shores of the Big Island and possibly Maui. These surf impacts will heavily depend upon the intensity of Calvin as it moves through the Hawaii region.
