The Lowdown
Right then, let’s have a look at what’s cookin’ for Wainui Bay Chalet. We’ve got a pretty mixed bag over the next couple of weeks, but there is a glimmer of hope if you’re patient.
The water’s sitting at about 55°, which is a bit colder than normal for this time of year – you’ll want a decent wettie.
Right off the bat, things are looking fairly average. Thursday the 13th has some surfable waves at around 3ft from the SE, but with a light rain and a cross-off breeze, it’s nothing to write home about. The energy’s pretty weak (178). We then hit a real dry spell. From Friday the 14th all the way through to the morning of Wednesday the 20th, it’s a write-off. The wind is all over the shop – cross, cross-on, onshore – and even when the swell gets some size (like the 12ft monster on Monday the 17th), the conditions are just ugly. The combined energy gets up there (3153), but it’s a messy, strong cross-onshore wind that’ll chew it all up. Tuesday the 18th and Wednesday the 19th have the same problem: decent sized swell but the wind just ruins the party. It’s a blank run of nearly a week with nothing worth paddling out for.
Things start to turn on Thursday the 20th. It’s still marginal, but you can see the tide turning. Then, Friday the 21st of August morning is your standout. Wainui Bay Chalet is a very consistent spot, exposed to the SSE, and the swell will be coming in from that direction. We get a nice 4ft of SE swell with a long period of 12 seconds, and the wind goes glassy, offshore from the NW at just 3 mph. The combined energy is a solid 566. That is clean surf, my friends. It won't be huge, but for a wave that’s usually good when it’s clean, this is the one to aim for. You might have some company though – the word is crowds get in there sometimes.
The Saturday the 22nd also looks good, with a moderate offshore from the WNW cleaning up a smaller 3ft to 3ft SSE swell, still with that lovely long period. It’s not as punchy as Friday, but still a fun option.
Heading into the second week, things get smaller and more inconsistent again, with a lot of “ordinary” conditions. There is a big red flag on Wednesday the 26th of August morning though – the forecast says an 8ft NE swell rolls in, but the note is clear: that’s too big for this break. So, keep that in mind.
So, the call is simple: If you’ve been holding out, make your move on Friday morning the 21st of August. That’s your best window for clean, lined-up waves. The rest of the forecast is mostly about waiting or dealing with windy mess.
