Waiehu beach park Surf Forecast and Surf Report

Alright folks, it’s Rusty here. Let’s be straight with you—this outlook for Waiehu Beach Park is a tough one to write. For the next couple of weeks, the ocean is just not playing ball for us paddle surfers. It’s not a total blank, but the conditions are pretty rough. The swell is there, but the wind has got it all chopped up and messy, making it a real struggle.

Looking at the whole 16-day window, we’ve got a lot of onshore and cross-onshore wind, mostly from the ENE. That’s going to put a bump on everything. The water temp is sitting at a normal 80°, so no worries there, but the surface is going to be a mess. If you’re a kiter, this might look like a playground, but for us on a surfboard, it's a battle.

Let’s run through it. The start of the period, the 17th and 18th of August, we’ve got some small, weak swell around 4-5ft with a short period of 7-8 seconds, and a cross-on breeze. It’s just poor. The energy is weak, around 181-209, so there’s nothing to get excited about.

Through the middle of the week, the 19th to the 22nd, the swell drops right off, down to under 3ft on a couple of days with periods as low as 6-7 seconds. The wind is still annoying. There’s a slight improvement on the 20th afternoon with a lighter breeze, but the swell is tiny. It’s basically a lake with ripples. Honestly, not worth getting wet for.

The weekend of the 23rd and 24th brings a bit more size, with the swell picking up to around 5-6ft on the 23rd and 24th. The period gets a little better too, up to 8-9 seconds. But, the wind is still cross-on and picking up to 15 mph. This is where it gets really frustrating. The energy is building, from 423 up to 542, but it’s all being blown out. It's messy, lumpy surf.

Then, from the 25th through the 27th, we see the swell really start to fill in, reaching 7-8ft. There’s even a risk of thunderstorms. The energy is strong, hitting 812 on the 27th. This is a serious amount of water, but it’s still accompanied by that persistent 12 mph cross-on wind. It's big, but it's ugly.

Now, here’s what looks like the most interesting window, but with a big caveat. On the 28th of August, the swell jumps to a solid 10ft with a 10-second period. The energy is very strong at 1580. This is the biggest pulse of the whole run. But, and it’s a big but, it’s still cross-on with a 12 mph wind. The finder flags it as marginal, giving it a 1 out of 10. This is expert-only territory. Over 8ft is for pros, and with that wind, it’s going to be a washing machine. It might be better to just watch this one from the beach. The 29th sees it back down to around 8ft, still with the same story.

After that big pulse, the swell fades fast. The 30th and 31st drop back down to 5-6ft, and then we’re back to under 3ft for the start of September. The wind stays on it, too. So, the final few days of the period are just a return to the small, messy stuff.

So, what’s the verdict? The single best day on paper is the 28th of August. There’s a big swell, but it’s going to be blown out. For a regular surfer, this entire forecast is a no-go. It’s a long stretch of poor conditions. The only people who might get something out of it are the experts on that one big day, and even then, it's a gamble. The rest of the time, the kites are going to be having more fun than us. Stay patient, keep the board in the car, and wait for a better window.

Rusty.
