Keaulanas Surf Forecast and Surf Report

Right, listen up folks, it’s Rusty here. Let’s get into it for Keaulanas.

The long-range picture is a bit of a mixed bag, to be honest. We’ve got a few windows of clean, offshore lines early on, but the back half of the period is looking a bit sloppy and weak. The first couple of days are where you want to be, no question about it. After that, we’re just scraping by on some smaller, less organized swells until the very end. Don’t get too excited about that far-out stuff; we’ll see how it plays out.

So, for Wednesday and Thursday — the 16th and 17th — this is looking like the pick of the whole run. We’ve got a solid SSW swell, around 0.9m, but with a long 18-second period. This is proper groundswell energy, and the water is a warm 27°, which is spot on for the season. The wind is offshore, from the ENE, which is going to keep these waves pretty clean all day. The combined swell energy is sitting at 575, which tells you there’s a reasonable push behind it, not massive, but enough to make it fun. It’s a beach and reef setup, so that long period might make it a little walled, but the offshore wind makes up for it. It’s a bit of a trek, and the break is consistent, but it gets sometimes crowded, so keep your head on a swivel. This is the standout period, no two ways about it.

We’ll see a little drop into Friday and the weekend, the 18th to the 21st. Swell comes down a touch to that 0.8m-1.1m range, and the period drops too, down to 15-17 seconds. The wind's still offshore in the mornings, but it's a lot stronger with the fresh breeze. The energy is still moderate, around 725 on Friday morning, but the quality just isn’t there, with the wave comments having a "marginal" and then "poor" feel to them. It’s not worth taking time off for.

Then we hit the middle of the week, the 22nd and 23rd. The swell is smaller, 0.5m to 0.7m, and the period is dropping into the 12-13 second range. The wind is still offshore, and on the 23rd we get a bit of glassy conditions, so it might be worth a look if you’re desperate. The combined energy is down in the 219 range on the 22nd, so it’s weak, but conditions are clean. It’s on the smaller side, but it could give up a couple of fun ones.

Alright, so looking at the second week, from the 24th of September onward, it gets tricky. The swell stays small, that 0.7m-0.8m, and the wind really starts to blow from the ENE at 25-30 km/h as a fresh breeze. It’s mostly cross-off, but the wave comments start sliding into "poor" territory. There’s one last glimmer on the 26th with a bit of an offshore wind, but the swell is small, and the magic is gone. The combined energy stays in that low to mid 400s at best, which is weak, and a lot of the time it’s in the 300s. Honestly, this run of small, wind-affected surf from the 24th through the 30th isn't looking great. The wave heights are just not there, and the period has shortened right up, so the surf will be crumbly and weak.

To sum it up, get on it early, Wednesday and Thursday are your days. After that, it’s a case of smaller waves and more wind, and nothing really stands out as a must-surf session.

Rusty out.
