Swell Summary
Several pulses of medium-period N and NNW swells are expected to arrive through the weekend, with the swell gradually shifting to the NNE (010 degrees) early next week. Wave height observations are rising on nearshore buoys right now and should peak late today. Due to the direction of the swell, north facing shores of the Big Island may need to be added as the swell. This will be a long lived event with elevated surf along N facing shores into next week.
Relatively small but persistent medium to long-period S (170-180 deg) and SSE (140-160 deg) swells will continue for at least the next couple of days, keeping surf near seasonal averages along S facing shores.
