The Lowdown
Alright, Rusty here, checkin' in on the local surf. Let's see what we got brewin' for the next couple weeks. The good news is we got swell comin', and some sweet windows of offshore wind are lining up. The water is sittin' at 55°, which is a bit colder than normal for this time of year at Wainui Bay Chalet, so don't forget the extra rubber.
First off, we're lookin' at a bit of a slow start, but things start gettin' interesting from Monday the 24th of August mornin'. The swell is small, only 3ft from the SSE, but it's got a bit of a background pulse (124 combined energy). What makes it worth a mention is that glassy, clean skin with a light WNW offshore breeze. It's a surfable wave, but it ain't gonna blow your mind. Tuesday mornin' the 25th is a step up with 3ft of SSE swell (248 combined energy) and another WNW offshore. It's a nice little window for a quick session before work, but still on the smaller side.
Now, keep your eye on Wednesday the 26th. That mornin' we got 2ft of swell, but the period jumps to 18 seconds – that's proper groundswell energy. Combined energy is 377, which is moderate. And the wind? Light WNW offshore, clean as a whistle. Because it's a long-period swell, it might be a bit straight for the beachys, but at Wainui Bay Chalet, that longer period should draw out some nice lines. This is where you wanna be.
But the standout, without a doubt, is Thursday mornin', the 27th of August. We got 4ft of SSE swell with that same 18-second period, and the combined energy is 722 – now we're talkin' moderate to strong energy. The wind is light NW and offshore. This is clean, rippable, and has some push. This is the best session on offer in the near term. Crowds are sometimes a thing here, so you might have to share, but with this quality, it'll be worth it.
Friday the 28th keeps things tickin' with 4ft of SSE swell (492 combined energy) and a north offshore breeze in the mornin', cleanin' it right up. Afternoon gets a NNW offshore as well. Good, consistent options here.
We hit a bit of a lull from Saturday the 29th into the first few days of September, with wind switchin' onshore and swell droppin' off. Sunday the 30th is a write-off with strong wind. There's a small gap of a couple of days with very ordinary conditions.
Now, lookin' way out to Tuesday, the 1st of September – wow. The forecast is showin' 8ft of SSE swell (5427 combined energy) in the mornin'. That is *very strong* energy. The wind is offshore and light. But, here's the thing: for an intermediate spot, that's a big, powerful wave. It might be workable for experts, but for most of us, that's a ledge. It's worth notin', but keep your wits about you.
Wednesday the 2nd of September settles back to a more manageable 5ft (706 combined energy) with a fresh WNW offshore. That's a clean, drivable day. After that, the second week is a bit more inconsistent with smaller swells and up and down wind, but keep checkin' back.
Signin' off, 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.
