Waiehu beach park Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here, and the surf outlook for Waiehu beach park is a bit of a test of patience.

The next couple of weeks are looking pretty average, to be honest. We're locked into a long stretch of cross-onshore winds that will keep the ocean looking chopped up and messy. The swell is mostly coming from the east-northeast, which isn't the right direction for this spot—it wants that north-northeast to really wrap in. So for the first week and a half, the surf is going to be pretty poor.

The pattern starts with small, weak surf. Through the 30th and 31st, we have around 5ft of short-period windswell (7-8 seconds), but with a moderate 12-15 mph cross-on breeze, it's going to be lumpy and uninviting. The combined swell energy is weak to moderate, at 200-370, which is just not enough to build any decent shape. It's the kind of surf you'd look at and decide to do something else.

Moving into the first week of September, the size holds around 5-6ft, and the winds stay cross-on. It's not going to improve much. The energy kicks up a bit, reading in the 380-470 range, but that doesn't help when the surface is chopped up. The 4th and 5th of September see a fresh breeze pick up to 18-22 mph, making conditions properly lumpy with sections closing out. This is mushy, weak stuff that's a struggle. I'd say the setup is more interesting for a kite surfer than a paddle surfer during this stretch.

Now, here’s a blip on the radar. On Sunday, September 6th, we finally get a pulse of proper long-period groundswell from the east, pushing in at 6-7ft with a 12-second period. The energy reading jumps to 1258, which is the strongest we've seen. But, and it's a big but, the wind is still cross-onshore ENE at 12-15 mph. It will be more powerful and have some push, but it's still going to be a messy, textured ocean. Not the clean day it could have been.

The real change comes on Wednesday, September 9th. The wind drops right out to a light 3 mph from the NE, which will be a glassy morning. The swell is the biggest of the whole period, a solid 10ft from the ENE with a 10-second period. This is the standout, but with that size, it's strictly for experts. The energy is a very strong 1699, and the light wind will finally make it look surfish. It's a shame the direction isn't more favorable, but this is the best we're going to get. The afternoon stays clean with light ESE winds, with the swell dropping to 8ft. After that, the swell fades and the cross-onshore winds return for the rest of the period, with the surf dropping to under 3ft by the 14th.

The water temp is about average for this time of year, so no surprises there. Basically, you've got one half-decent window on the 9th. If that's too big or you're not an expert, you're waiting for that swell to drop but the wind to stay light. Right now, it looks like a waiting game.
