The Lowdown
Alright folks, Rusty here. Let's have a yarn about what's ahead for Wainui Bay Chalet. The ocean's got a bit of a mixed bag for us over the next couple of weeks, but there are definitely some windows worth paddling out for.
We've got a solid week or so of smaller, cleaner swells kicking things off, but hang tight because the real muscle shows up right at the end of the month and into September. Water temp is sitting at 55°, which is a bit colder than we normally see this time of year, so don't forget the wetsuit.
The best bet for the whole period is hands down Monday the 31st of August morning. I know it's a week away, but keep that date free. We’re looking at a solid 12ft swell rolling in from the SSW. The combined energy is a massive 4255 – that's some serious power in the water. It’ll be too big for beginners, but for the experienced crew, it’s game on. The morning starts with a light 6 mph offshore northwest wind, keeping the lineup clean. The afternoon still pumps a 7ft swell from the SSE, but that wind swings to a light cross-shore, so it won't be as perfect. Just a heads up, this spot can get a few people around sometimes.
The rest of the first week is about manageable, fun waves. Wednesday the 26th morning is a nice little starter: a clean 2ft SSE swell with a dreamy 6 mph offshore from the NW and a very long 18-second period. The wave energy is moderate (393), but with that period and glassy wind, the points and reefs will be your friend here—it’ll be too straight for the beach breaks. Thursday the 27th sees the swell push up to 4ft in the afternoon, but that comes with a 9 mph onshore wind from the SE. Friday the 28th bounces back nicely with a 3ft swell and clean cross-offshore wind in the morning.
After that initial run, the surf dials right back. From Saturday the 29th through to the 5th of September, we’re looking at mostly knee-to-waist high stuff, with a lot of 1.0ft to 2ft days. A few of those mornings have clean offshore winds, but it’s very ordinary. There is a standout window on Tuesday the 8th of September afternoon. It’s a long way out, so don’t book your flights yet, but the models are showing a clean 5ft SSE groundswell with glassy conditions. The energy is strong (1144) and it’s marked for experienced surfers – that’s one to keep an eye on if the forecasts hold.
The 1st of September is a beast, with a 15ft south swell and a massive energy reading of 8128. It's sheer power and it's too big for the break, even with a moderate cross-shore wind. Look for it to be more of a spectacle than a session for most, unless you’re on a gun.
So, to wrap it up: the next few days offer clean, small waves for a cruise. The standout is Monday the 31st of August morning for a proper hit of size and cleanliness. After that, it’s a long flat spell before a promising glassy pulse on the 8th of September. Keep your eyes on the charts for that one.
Rusty.
