Swell Summary
A moderate long period northwest swell should steadily fill in across the smaller islands this morning and peak during the day today. Based on the latest buoy readings from buoy 51001 and 51101 northwest of Kauai, surf heights are expected to remain below High Surf Advisory (HSA) thresholds along north and west facing shores. However, a larger west-northwest to northwest swell will arrive Sunday, and will likely result in HSA level surf for exposed shores Sunday night into Monday. Due to the westerly component of this swell, surf heights may approach HSA thresholds for west facing shores of the Big Island on Monday.
Short period easterly wind wave swell will trend upward this weekend as trade winds gradually increase. As the trades strengthen even further later next week, we should see another uptick along east facing shores the second half of next week. South-facing shore surf will remain at background levels for the next several days.
