Keaulanas Surf Forecast and Surf Report

Alright, let’s get into it.

The next couple of weeks look a bit on the small side for Keaulanas. The good news is that there's a decent stretch of clean, glassy conditions early on, but the swell is pretty modest. We do have a standout window further out, but you’re gonna have to be patient for it.

Starting Tuesday afternoon the 18th, we’ve got some waist-high lines wrapping in. It’s not going to blow your mind, but the water’s warm at 81°, which is about average for this time of year. There’s a moderate offshore breeze, and the swell is coming from the south with a solid 13-second period, so the shape should be okay. It’s a bit soft, but it’s clean.

Wednesday the 19th and Thursday the 20th are where it’s at for the first part of the week. The wind drops right out, especially Thursday morning when it’s dead glassy. The swell stays small, around 1ft to 2ft, but that long-period south-southwest energy means the waves will have some push to them. This is the kind of small, clean surf that’s fun on a log or a fish. Keaulanas is a consistent spot, so even with the smaller size, there should be enough to keep you busy.

Friday the 21st looks similar, with tiny glassy conditions and a little more energy in the water. It’s still in that 2ft range, and with the light winds, it’s worth a paddle if you’re keen for a few clean ones.

Then the trade winds kick in. From Saturday the 22nd onward, we’re looking at a strong ENE flow that’s going to put a bit of a chop on things. The swell stays small, around 2ft to 3ft, but the wind will make it messy. Saturday afternoon gets particularly poor. This pattern holds through the end of the month, with mostly cross-off winds and small, short-period swell. It’s really not worth your time unless you’re desperate.

There’s a gap here with no proper surf on offer from late August through the first days of September. Sunday the 30th bottoms out with a tiny 1ft swell, so it’s pretty flat. This dry spell is fairly normal for the area.

Now, here’s the one to circle on the calendar. Tuesday the 1st of September in the afternoon, the swell starts to fill in. The wind is offshore, and you can feel the energy building. But it’s Wednesday the 2nd that’s the standout. We’re looking at a solid 4ft of south swell with a long 19-20 second period. This is proper groundswell. The energy jumps right up, with a combined value of 1124, which is strong. It’s going to have some serious push.

Both Wednesday morning and afternoon look excellent. The wind is light and offshore, keeping things clean. This is the kind of day that will have the experienced surfers out there smiling. It’s not for the beginners, though. At 4ft with that long period, it’s got some power behind it, and the sets will be solid. This is definitely the best on offer in this whole 16-day stretch, but being that far out, keep in mind the forecast can shift a bit. It’s promising, but don’t book your flights just yet.

Overall, there’s some small, clean fun to be had early on, but the real juice is waiting for that Wednesday the 2nd. Be patient for that one.

Rusty.
