The Lowdown
Alright folks, Rusty here. Let's have a look at what Waiehu Beach Park has in store for us over the next couple of weeks.
First up, the water temp is sitting right on 80°, which is pretty much bang on average for this time of year. No surprises there.
Right now, and for the next several days, it's a bit of a struggle. We've got a consistent run of cross-onshore winds from the ENE that are just ruining the surface. The swell is there, mostly around 3ft to 4ft from the ENE with a short, weak period of 8 seconds, but the combined energy is weak to moderate (176). The surf is choppy and messy, and frankly, not worth paddling out for. This poor stretch looks set to last right through until the end of August.
There is a tiny glimmer on Thursday afternoon, the 20th of August. The wind drops right out and it goes glassy. The swell is only 3ft from the NE with a 7-second period and low energy (118), so it’s surfable but very ordinary. You might get a few little crumbly ones if you're desperate for a splash, but don't expect much.
The real interest, and I mean the *only* real interest in this whole outlook, starts to build as we move into the first week of September. The wind finally switches around to an offshore direction from the NNE, which is the optimum direction for this spot. On Tuesday the 1st of September, we see the swell jump to 7ft from the E with a 10-second period and the energy goes through the roof – we’re talking strong energy (1603). The wind is onshore at 12 mph, which keeps the quality marginal.
But Wednesday the 2nd of September is the standout. The morning shows 6ft of swell from the E, a nice 10-second period, and that offshore wind from the NNE drops to a light 6 mph. The energy is still very strong (1221). The conditions are described as "marginal" but with offshore wind and a solid, longer-period swell on a reef and point set-up like Waiehu Beach Park, this is the one to aim for. The afternoon cleans up even more with the wind going almost glassy at 3 mph. It's still over 5ft, so this is more for the experienced crew.
So here's the deal: don't bother with the next week and a half. It's a write-off. Keep your eyes on Wednesday, the 2nd of September. That’s your window. The combination of clean offshore wind and a proper groundswell with real energy behind it is the best on offer by a long shot. It’s a long way out, so keep an eye on the forecasts, but it's looking promising.
Rusty.

Information about the Waiehu beach park Surf forecast
The above surf forecast table for Waiehu beach park provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waiehu beach park can be found by selecting the local surf guide option on the grey menu. Our Waiehu beach park surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Waiehu beach park) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
Waiehu beach park is 5 km (3 miles) from Wailuku. If you plan a vacation in Maui, look for hotels and other accommodation in Wailuku. Wailuku has rooms for a wide range of budgets as well as car hire and transport links.
