The Lowdown

G'day, Rusty here. Alright, we’ve got a mixed bag coming our way at Wainui Beach – Stockroute over the next couple of weeks. The water's sitting at 55°, which is a bit colder than normal for this time of year, so you’ll want a good wetsuit.

The run starts on Thursday afternoon, September 3rd. We’ve got a solid 3ft SSE groundswell with a nice long 13-second period rolling in. The wind is WNW, light and offshore, setting up clean, groomed lines. The combined energy is a solid 318 (moderate), and this is actually the best session in the first week. It’s advanced-level surf, and it’s very consistent, but be aware that crowds can show up here. This is the standout in the early days.

Friday and Saturday are a real letdown. The swell drops right off, getting under 2ft, and the wind swings around to cross-off or cross-on. Saturday morning has a light offshore breeze but with a tiny 1ft of swell, you’d be luckier to find a ripple. The pocket stays deep and quiet through the start of the next week.

By Sunday morning, September 6th, there’s a faint pulse with 2ft SSE swell and a moderate WNW offshore blowing, but it’s ordinary at best—not worth paddling out for. A short window of glassy conditions pops up on Tuesday morning, September 8th, but the swell is only 0.7ft. Nothing doing.

Then we get a spike Wednesday morning, September 9th: 4ft of S swell but with a short, weak 7-second period (combined energy 206). A cross-off SW breeze keeps it clean, but the quality isn’t there for a good session. The following days stay small and messy until Friday morning, September 11th.

Now, here’s something to keep an eye on. Friday morning, September 11th, sees a tiny 1.0ft SSE groundswell, but check the period—22 seconds! Very long-period energy (combined energy 258, moderate) and a gentle offshore WNW breeze. It’s going to be clean but those long-period swells at a beach and reef setup like this can break a bit straight, so you’ll want to hunt for a wedge. A promising but cautious call.

Saturday morning, September 12th, holds similar: 1ft SSE swell with an 18-second period and a light WNW offshore. It’s clean and rideable, but don’t expect much push. Then Sunday, September 13th, the ocean turns angry. An 8ft SSW swell on Sunday morning moves into 20ft S swell by Monday, September 14th, with combined energy readings skyrocketing into the thousands—24543 (very strong). The wind is cross-off SW, so it’s clean, but this is expert-only territory. The swell is too big for the break to handle for most surfers. If you’re an absolute charger with a big-wave gun, you might look at it, but realistically, this setup looks more interesting for kite surfing than paddle surfing.

The swell eases through Tuesday, September 15th, and by Wednesday morning, September 16th, we get a nice 3ft SE swell with a moderate 11-second period and a light NNW cross-off breeze. It’s clean, the combined energy is 268 (moderate), and it’s a solid end to the outlook. That Wednesday morning is another good shout for a fun session after all the chaos.

Overall, Thursday September 3rd afternoon is your best bet in the first week, and Wednesday September 16th morning is the pick of the second week—just remember long-range forecasts can shift, so keep an eye on it.

Rusty.
