Hawaii High Surf Advisory Update South Facing Shores 7 to 10 Feet Wednesday April 8th

Good evening, this is your Hawaii Surf Zone Forecast for Tuesday, April 7th through Wednesday, April 8th, 2026. A High Surf Advisory remains in effect for all south-facing shores of the Hawaiian Islands through Wednesday night. Here's what's happening out there on the water. Offshore and near-shore buoys are painting a picture of steadily rising energy this evening, particularly in those longer 18 to 22 second period bands. This swell will continue climbing through the night and peak Wednesday above advisory thresholds. We're looking at south-facing shores consistently in the 7 to 10 foot range both Wednesday morning and afternoon across all islands. Meanwhile, up north, a moderate long-period northwest swell is filling in nicely this evening and will peak Wednesday, though it'll stay just below advisory levels. A smaller short-period north-northeast swell will also work in before peaking tomorrow and dropping off as we head into Thursday. Looking ahead to later in the week, as that long-period south swell starts to decline Thursday, strong to near gale force southerly winds are expected to develop and really intensify Thursday night into Friday. Those increasing southerly winds will trigger a rapid buildup of short-period energy, bringing surf heights right back above advisory thresholds with large, disorganized surf expected along many south-facing shores Thursday into Friday. Let's break down conditions by island. On Kauai, tonight expect 6 to 8 foot surf on south-facing shores, ramping up to 7 to 10 feet Wednesday. North-facing shores will see 5 to 7 tonight and climb to 7 to 10 Wednesday. West and east-facing shores will remain smaller. Over on Oahu, south-facing shores are currently 6 to 8 feet and will rise to 7 to 10 feet Wednesday.
