Kewalos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cooking for the Kewalos stretch. Honestly, it’s a bit of a mixed bag for the next couple of weeks, and we’ve got a long wait for anything truly special.

The first week is pretty grim. From Saturday the 29th right through to the end of August, we’re stuck with a strong cross-off wind from the ENE at 22 mph, with only small swell around 5 ft to 6 ft. The period is short, around 7 seconds, so the waves will be weak and lumpy. The combined energy is moderate, sitting around the 463 to 619 mark, but the wind is just too strong for it to be any good. Honestly, it’s a write-off for a paddle. If you’re into kite surfing, that setup might be interesting, but for a surfboard, it’s a no-go.

Things don’t get much better heading into the first week of September. Monday the 1st and Tuesday the 2nd stay marginal. The real kicker is a pulse of long-period groundswell from the S on Wednesday the 2nd, with a period of 16 seconds and a combined energy of 834, but the swell height is only about 3 ft. That’s a tease – a long wait for a tiny wave. The wind is still a fresh cross-off, so it’s not clean.

We’re looking at a gap of several days with no real standout surf. The best of the bunch starts to appear around Tuesday the 8th of September. The swell picks up to 8 ft from the ENE, with a period of 10 seconds and a combined energy jumping to 1926. That’s moderate to strong energy. The wind is still a cross-off, but it drops to a moderate breeze at 19 mph. This is getting more interesting. The wave size is pushing 8 ft, so it’s getting into expert territory, definitely not for beginners.

The real highlight, and the only true standout in this whole outlook, is Thursday the 10th of September. The swell peaks at 10 ft from the ENE, with a period of 8 seconds. The combined energy hits 2365, which is strong. The wind is a moderate breeze at 16 mph, and it’s still cross-off. This is a powerful, chunky swell. For a reef break like Kewalos, that’s a proper day. The size means it’s strictly for experienced surfers only. The water temperature is a warm 81°, which is about average for the time of year.

After that, things fall apart. Friday the 11th brings a change in wind to a cross-on from the SE, and the swell swings to the south, making it lumpy and choppy. By Saturday the 12th, the wind goes onshore, and the energy drops right off. The final days of the outlook, like Sunday the 13th, go completely flat with about 4 ft of weak, short-period swell and barely any wind. It’s glassy, but there’s nothing to ride.

So, to sum it up: the first week is a bust. The window from Tuesday the 8th to Thursday the 10th of September is your best bet, with the 10th being the clear standout for strong, powerful waves. After that, it’s back to the drawing board.

Rusty.
