The Lowdown
Alright, let’s get into it.
We’ve got a slow start, but the surf is set to kick off from Tuesday morning, August 25th, and the first real standout is Wainui Beach - Stockroute. This spot is an exposed beach and reef setup that loves swell from the SSE, which is exactly where our energy’s coming from. Water temp is sitting at 55°F, so it’s a bit colder than normal for this time of year—about 2°F cooler—meaning you’ll want that extra rubber.
Tuesday morning (August 25th) kicks off with a clean 3ft SSE groundswell running at 13 seconds, light offshore NW breeze at 6 mph, and moderate wave energy (244). That’s a nice little session to get things started, but don’t expect much size.
Wednesday morning (August 26th) looks sweet too: 2ft of SSE groundswell, period jumping to 18 seconds—a proper groundswell—and a clean offshore NW wind at 9 mph. The combined energy climbs to 377, so there’s a bit more push. This one’s clean and should offer real shape.
Thursday morning (August 27th) is a write-off with cross-onshore S winds and choppy conditions, but things improve heading into Friday morning (August 28th). Friday morning offers 4ft SSE swell at 14 seconds, light offshore-ish N wind, and clean conditions with 531 energy. That’s definitely worth a paddle.
The real standout, though, comes on Tuesday, September 1st. The morning session delivers 6ft of SSE groundswell at 16 seconds, a light offshore/cross-off NNW breeze, and strong wave energy at 1463. This is clean, powerful, and for experienced surfers. The afternoon gets bigger (7ft) but picks up a cross-on wind, so stick to the early sesh.
Another notable window is Friday, September 4th. Both morning and afternoon show 6ft SSE swell at 13-14 seconds, clean conditions with cross-off NNW winds, and energy readings around 1146 to 1278. This is solid, well-shaped swell, but it’s not a rare gem like the 1st. Keep an eye on crowds here because this break can get busy sometimes.
Later on, Monday, September 7th morning sees a 7ft S swell at 9 seconds with a light cross-off wind. That’s a bit more energy (1043) and a shorter period, but for experienced surfers, it could still be fun if you pick your peak. The direction is different here—S instead of SSE—so it might wrap differently.
There’s a gap after August 27th through the 30th where the surf is small and ordinary or blown out, but the second week picks up nicely. Overall, the best on offer is Tuesday morning September 1st, with Friday September 4th a close second.
