The Lowdown
Alright folks, Rusty here. Let's get into what's shaping up for Wainui Bay Chalet. No point beating around the bush—this is a tough forecast. We've got a lot of waiting ahead for anything decent.
The next good session doesn't show up until early Thursday morning, the 20th of August. Before that, it's mostly a write-off. Thursday through Sunday, the 13th to the 16th, is a mess of cross and onshore winds with junk swell. We've got a bit of size in there—Saturday morning the 15th sees a 7ft swell from the E, but it's flagged as too big for this break. The early window is a dead loss.
The real standout—and I mean the *only* real standout in this whole 16-day outlook—is the morning of Thursday the 20th of August. The swell is a solid 6ft from the SE (11 second period), with strong energy. That's some proper grunt. And the wind? A light cross-offshore breeze from the WSW at 9 mph. That's going to set up clean lines.
This spot is very consistent and exposed to the SSE, which is exactly what the guidance says it wants. The swell direction is ideal, and those offshore conditions will have the faces looking smooth. It's marked as excellent for experienced surfers, and that's fair—this isn't a beginner wave at that size. It's solid, powerful, and clean. This is the session to target.
After that, the rest of the forecast fades. Friday the 21st has a morning window with a tiny 3ft SSE swell and offshore NW wind at 6 mph. It'll be clean but gutless. Saturday the 22nd is similar, with 3ft SSE and a light offshore again, but again, marginal power. Then we're into flat, weak junk through to the end of the month. One more glimmer comes Tuesday morning the 25th of August: a 4ft SSE swell with a long period of 14 seconds, light cross-offshore breeze. It could offer a clean, long-period runner, but it's not the standout that Thursday the 20th is.
Look, the water's a bit colder than usual right now at 55°, which is about 2° below the average for this time of year. It's noticeable, but not freakish.
To sum it up for you: Thursday morning, August the 20th, is your day. Get on it. The rest is either blown out, too small, or just plain messy. Keep an eye on that Tuesday the 25th as a potential backup, but don't hold your breath.
