The Lowdown
Alright mates, Rusty here. Let’s break down what’s coming for the next couple of weeks. Honestly, the whole 16-day window is a bit of a struggle for decent surf. There’s a long stretch of small, weak swell and cross-off winds that just aren’t going to give us anything to write home about. There’s really only one day that might get the blood pumping, but it comes with a few headaches.
The first real pulse shows up on Wednesday the 5th of August. Wednesday afternoon sees a 5 ft swell from the NE with a short period of 9 seconds, and a moderate energy reading (334). The wind is a cross-off from the NE at 9 mph, which isn't ideal for S-Turns. It’s a reef break, so it’s an intermediate spot, but the short period and cross-off wind will make it a bit messy. It’s the best of a bad bunch for that day.
Then we hit a proper lull. From Thursday the 6th of August all the way through to Sunday the 16th of August, the swell stays tiny, mostly 0.7 ft to 2 ft, with weak energy. The wind stays consistently cross-off from the ENE at 15-19 mph, which is a real downer for a reef that needs clean offshore winds. The water temperature is about average for the time of year, so no surprises there.
The one standout is Monday the 17th of August. On Monday morning, we get a 5 ft swell from the NE, with a short period of 9 seconds and a strong energy reading of 416. Monday afternoon keeps it going with a solid 5 ft from the NE, 8-second period, and 345 energy. This is the biggest swell of the whole run. But the wind is still a cross-off from the ENE at 19 mph, which is a fresh breeze. For a reef break, a cross-off that strong makes it a rough, bumpy mess. It’s also a bit too big for beginners. It’s the only real pulse of the entire forecast, so it’s the best on offer, but it’s not a classic. The short period means the waves will be a bit fat and weak, not the long, clean lines you’d hope for.
After that, Tuesday the 18th and Wednesday the 19th of August are back to the small stuff with 1 ft and weak energy.
So, to be straight with you: if you have to paddle, the 17th of August is the only day that might be worth a look, but don’t expect a glassy session. The rest of the two weeks is a right-off for S-Turns. The conditions are more suited to a kite if you’re into that sort of thing. The crowds are listed as "sometimes" for S-Turns, so on that 17th, you might have a few others with the same idea, but it’s not going to be a zoo.
Rusty.

Information about the S-Turns Surf forecast
The above surf forecast table for S-Turns provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at S-Turns can be found by selecting the local surf guide option on the grey menu. Our S-Turns 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 (S-Turns) 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 S-Turns 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.
S-Turns is 22 km (14 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.
