The Lowdown
Alright folks, Rusty here. Let’s have a look at this next stretch. We’ve got a bit of a mixed bag, but there are some real moments to get excited about if you’re patient.
Overall, the pattern is building towards a couple of standout windows, but the next few days are a write-off. The first real action doesn’t kick off until the morning of Tuesday, September 2nd, so you’re looking at a solid gap with no recommendations until then. After that, the size and energy come in, but conditions are fickle.
The water is a bit colder than normal for this time of year, sitting at 55°.
Wainui Bay Chalet is the only spot on the menu, and it’s a very consistent, exposed break that handles a south-southeast swell best.
Monday, August 31st is a total loss. Tiny little 2ft waves with a fresh cross-off breeze and very weak energy. Not worth getting wet.
Then Tuesday, September 1st rolls in with a massive pulse. The morning shows a solid 10ft swell from the south, with a moderate 13-second period and a massive amount of energy. The problem? It’s too big for this break. Cross-shore wind from the southwest doesn’t help. The afternoon drops to 6ft but turns cross-on and choppy. Not your day.
Now, Wednesday, September 2nd is the real standout. Morning brings a clean 6ft swell from the SSE with a 14-second period and strong energy. The wind is offshore from the northwest, a moderate breeze, and the conditions are clean. This is good for experienced surfers. Then the afternoon gets even better – glassy conditions, no wind, and a 6ft swell with a long 17-second period and very strong energy. That’s a proper groundswell, and it’s going to be absolutely clean. This is the best on offer, no question.
Thursday, September 3rd still has some fun options. A 4ft SSE swell in the morning with a moderate offshore wind and a clean 3ft in the afternoon. Good, but not the standout.
Friday, September 4th through Sunday, September 6th is a real lull. Tiny waves (1ft to 3ft), weak energy, and mostly ordinary conditions. Not worth rushing.
Monday, September 7th is a messy one. A 5ft swell in the morning is ruined by a fresh cross-shore, and the afternoon brings a 10ft swell with a cross-on wind and lumpy chop. Avoid.
Tuesday, September 8th is another massive day. A 15ft swell from the south with a 11-second period and enormous energy. But again, it’s too big for this break, and the cross-on wind in the afternoon makes it a mess. The morning is clean with a light wind, but that size is for experts only.
The rest of the second week (September 9th to 14th) is mostly poor. Small swells, poor winds, and marginal conditions. A few clean moments on the 10th and 13th mornings, but with very weak energy.
The final standout arrives on Tuesday, September 15th. A clean 6ft swell from the SSE with a very long 16-second period and strong energy. The morning has a light cross-off breeze from the NNW, making it clean. This is another excellent session for experienced surfers, though the afternoon goes cross-shore and messy. Mark this one in your calendar.
So, to sum it up: Wednesday, September 2nd is the absolute best bet, with glassy afternoon conditions and a solid groundswell. Tuesday, September 15th is a close second for a long-range, promising session. The rest is mostly waiting.
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.

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.
