The Lowdown

G'day, Rusty here, and I've got a look at the waves coming up for Wainui Bay Chalet. The next couple of weeks are a bit of a mixed bag, but there are a few windows that'll get you frothing. The water temp is sitting around average for this time of year, so nothing unusual there.

The real standout is the first decent session. Sunday morning, August 9th. We've got a clean 3ft swell rolling in from the SE with that 11-second period – that's a nice groundswell with proper energy. The wind is a light cross-off from the NNW at 6 mph, and the combined energy is a solid 346, meaning moderate wave energy. This is the best on offer early on, with clean conditions and a consistent lineup. The cross-off wind will keep the faces tidy, and the 11-second period means longer waits between sets but plenty of push when they come. The SE swell is a good match for the optimum direction here.

The next little window is Monday morning, August 10th. The swell drops to 2ft from the SE, still with a 10-second period, but the wind is a clean offshore from the WNW at 6 mph. The energy is only 97, so it's weak, but it's surfable and clean. It's a bit of a small day, but if you're on a longboard or a fish, you might get a couple.

Then we get a proper pulse on Tuesday morning, August 11th. The swell jumps to 6ft from the SSW, but the period is a short 8 seconds. The combined energy is 765, which is moderate to strong. The wind is a cross-off from the WSW at 9 mph. This is a solid, punchy swell but that short period means it'll be a bit crumbly and less powerful. It's doable, but it's not the cleanest.

After that, things get messy. The wind turns onshore and picks up, and the swell is all over the place. There's a big gap from Tuesday afternoon all the way through to Saturday morning, August 15th. That Saturday morning looks promising if you can wait. The swell is 5ft from the E with a 10-second period, and the wind is a clean offshore from the WNW at 9 mph. The energy is 457, moderate. That's a solid, clean day with proper shape.

The rest of the second week is a write-off for quality surfing. The wind is strong and cross-onshore, and the swell gets big – over 8ft in some cases – which is only for experts, but the wind ruins it. We're talking 12ft on Wednesday, August 19th, but with a fresh cross-onshore, it's just a mess.

The last little glimmer is Friday morning, August 21st. The swell drops to 4ft from the SE, with a 9-second period. The wind is glassy from the NE at 3 mph. The energy is 283, moderate. That's a glassy morning, perfect for a slow, clean session. The 9-second period isn't long, but the glassy conditions will make it way more fun.

And then the final note is Monday morning, August 24th. The swell is 6ft from the E, with a 9-second period, and the wind is a clean offshore from the WNW at 16 mph. The energy is 635, moderate. That's a clean, offshore day with a decent swell, but it's a full two weeks out, so keep an eye on the forecast.

Overall, the best bets are this Sunday morning, and then next Saturday morning. The lake looks more interesting for kite surfers during the big, windy, messy days in between. Keep your eyes on the horizon, and stay sharp.

Rusty.

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.
