The Lowdown
Right then, let’s talk about surf here on Maui.
Waiehu beach park is the only spot on the radar, and to be straight with you, it’s a tough stretch ahead. This break is a reef and point setup, consistent, and best for beginners, with the swell coming from the east-northeast.
The water temp is sitting at about 80° right now, which is just about normal for this time of year, so no surprises there.
For the next couple of weeks, the story is pretty much the same: poor surf conditions across the board. From Friday the 21st of August right through to the end of the month, we’re stuck with a persistent cross-onshore wind from the east-northeast, mostly at 12 mph, sometimes gusting to 16 mph. That breeze is just chopping everything up, making for messy, lumpy waves. Swell heights bounce around between 4 ft and 7 ft, but with the wind in the wrong direction, it’s all junk.
The combined swell energy does climb, hitting a moderate level a few times, and we even see a strong spike right at the end of August and start of September, but the wind ruins it. The early part of this run is just poor. You’ll see some longer period swell (16 seconds) arrive around Friday the 28th, which gives it some energy, but the cross-onshore wind makes it a write-off. The break is exposed to the swell, but that wind is the killer.
We finally get a slight shift around Wednesday the 2nd of September. The wind goes light and cross-shore, with a bit of a northwesterly feel, and the waves are marginal. Not great, but the first hint of something less terrible. Then on Thursday the 3rd of September, we get a little moment: the morning is glassy, wind is 0 mph. Swell is small, 3 ft from the east-northeast with a period of 8 seconds. The energy is weak (143), but it’s glassy. That’s the one small window for a surf, maybe some fun little crumbly waves for a log or a mid-length. But it’s small and short-lived, as the wind swings cross-onshore again in the afternoon.
After that, we’re back to poor conditions, with cross-onshore wind and choppy surf all the way through to Saturday the 5th of September. That’s a long gap of poor surf.
The only real standout, and I mean the only one, is that Thursday morning the 3rd of September. It’s a tiny, glassy window. Don't expect much, but it’ll be the cleanest surf of the whole 16 days. The swell direction (ENE) is fine, but the size is small. The rest is a battle with the wind.

Information about the Waiehu beach park Surf forecast

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Waiehu beach park may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
