Waimanalo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s cut through it. We’re looking at Waimanalo for the next 16 days, and I’ll be straight with you – it’s a pretty bleak stretch for surfing. The whole run is basically a write-off for proper waves.

There is no surf worth paddling out for in this entire forecast window. The first record tells us everything: Monday afternoon, 17th August, kicks things off with a 5ft swell from the ENE but a solid 16 mph onshore wind blowing straight into it. The water’s sitting at a warm 80°F, which is normal for this time of year, but that’s about the only good news. The combined wave energy is weak, sitting at just 262, and the period is short at 7 seconds – just wind-chop with no shape.

From Tuesday 18th right through to the end of the month, it’s the same story. Swell heights bob between 3ft and 8ft, but every single day has onshore or cross-onshore winds. The periods stay short, between 6 and 10 seconds, so it’s all disorganised, lumpy, messy stuff. Even when the swell pushes to 7ft or more, it’s blown out. The combined energy climbs up to over 1000 towards the end of the month, but without clean winds, that energy is just raw, choppy power – more for kites than paddles.

For the first week, the wind is relentless – moderate to fresh breezes from the ENE, never letting up. By around Saturday 29th August, you’ve got 10ft swell, but it’s still cross-onshore and choppy. On Sunday 30th August, the period stretches to 10 seconds, which is better, but that cross-on wind turns it into a lumpy mess. Then it drops off into September with tiny 3ft swell and howling 28 mph winds on Tuesday 1st September.

Honestly, there’s not a single standout session in here. If you’re desperate, maybe sneak a look on Friday 21st August morning when the wind drops to a light 6 mph breeze, but it’s only 2ft from the east with a period of 7 seconds – tiny and weak. Not worth the drive.

For an area that’s exposed to the ENE, we’re getting plenty of swell direction, but the wind never plays ball. The crowd profile says Waimanalo is “sometimes” busy, but with conditions this poor, you won’t have to worry about that. The break is fairly consistent, but when the quality is this bad, consistency means nothing.

So, to sum it up: no surf on offer for the full 16 days. It’s a blank run. The only positive? Forecasts can change, and this kind of extended poor run is not abnormal for the area when the trade winds lock in. Keep an eye on it, but don’t hold your breath.

Rusty.
