The Lowdown
Alright folks, Rusty here. Let’s have a look at what Wainui Bay Chalet has in store for us.
We’ve got a proper mixed bag over this 16-day window, with a clear standout early on and another promising pulse lurking right at the end. The water is sitting at 55°, which is about a degree colder than normal for this time of year, so you’ll want a decent wetsuit.
The pick of the forecast is hands down Wednesday the 2nd of September, first thing. We’re looking at a clean 6ft swell from the SSE with a solid 14-second period – that’s proper groundswell with real shape and push. The combined wave energy is pumping at 1448 (moderate-strong), and with a moderate offshore breeze from the NW, those waves will be peeling smooth. This is the one to circle. The morning session will be the go, as the afternoon swings onshore.
That morning is followed by Thursday the 3rd with a smaller but very clean drop. The swell eases to 4ft from the SSE, still with a nice 13-second pulse, and the offshore wind holds from the NW. Combined energy is 506 (moderate). Then, on Thursday afternoon, it goes glassy with a 3ft SSE swell – perfect for logging, light crowd depending.
We hit a flat and ordinary stretch from Friday the 4th through to Monday the 7th. Swell drops away to barely a ripple, with mixed winds and poor conditions. Not worth paddling out for.
Things start to wake up again on Tuesday the 8th with a building swell – 8ft from the SSE, 12-second period, clean on the morning. But here’s the thing: the file flags that as too big for this break. Combined energy hits 1548 (strong). Same story for Wednesday the 9th (7ft, 14-second SSE, 1835 energy). This is big, powerful groundswell, so unless you’re an experienced charger, I’d give it a miss. Thursday the 10th settles to a much more manageable 5ft from the SE with offshore winds in the morning – good call then.
The middle of the second week is a bit average again until we get a real beauty on the far side. Wednesday the 16th of September morning: glassy conditions, 6ft from the SSE with a very long 16-second period. That’s an incredible 1970 combined energy. This is a serious, powerful groundswell with dead-calm conditions. It’s going to be big and clean at the point, but watch out – that long period might make it sectiony on a beach break. For experienced surfers, this could be the best session of the whole run, though being two weeks out, it’s still a promising possibility rather than a lock.
If you’re a kite surfer, the big, windier days around the 7th and 8th with strong cross-shore winds and messy chop could be more your scene than paddle surfing.
Overall, Wednesday the 2nd morning is your surest bet for quality, and that last morning on the 16th is the one to watch.
Rusty.

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