The Lowdown

Alright folks, Rusty here. Gotta be straight with you—this 16-day window for Waiehu Beach Park is a tough one to call. There’s surf on offer, but the conditions are putting a real damper on it. The key issue is a persistent cross-onshore wind that just won’t quit, ruining the surface. The swell energy does build as we go, but the quality is poor throughout.

Looking at Monday the 17th, we’re starting off small and bumpy. Waiehu Beach Park (Maui) has 5 ft of short-period ENE swell (269 combined energy) but it’s already choppy with a solid 12 mph cross-on breeze. The afternoons are the same story—no clean windows.

The next several days, from Tuesday through the following Monday, the pattern stays locked in. Swell sizes bounce around between 2 ft and 6 ft, but with that relentless cross-on wind, the surf stays poor and mostly choppy. It’s just not worth paddling out for any kind of quality session.

We hit a stretch from around the 23rd to the 27th where the swell gets bigger—pushing past 7 ft and even hitting 8 ft by the 27th. The energy ramps up into the hundreds and even four-digit range (1035 combined energy), but again, the wind is cross-on, often around 12 to 19 mph, and there are rain showers and even thunderstorms in the mix. At this size, with these winds, the setup looks more interesting for kite surfing than paddle surfing. For the average surfer, it’s just blown-out and messy.

Towards the very end, on Sunday the 30th, the period stretches out to 10 seconds, giving a bit more push, but still the wind is onshore. It’s not a complete washout, but there’s no single standout day where everything lines up. The water temp is a balmy 80°F, which is about average for this time of year, so you won’t need a thick suit.

Honestly, there are no true standouts here. The entire 16 days is a gap with no clear recommendations. We’re in a rough patch where the trades have the upper hand. It won’t stay poor forever, but for now, it’s a waiting game. Keep an eye on the wind shifts before you commit.

Rusty.

A general guide to surfing at Waiehu beach park can be found by selecting the local surf guide option on the grey menu.

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.
