The Lowdown

Alright folks, Rusty here. Let’s have a look at this next stretch. We’ve got a bit of a mixed bag, but there are some real moments to get excited about if you’re patient.

Overall, the pattern is building towards a couple of standout windows, but the next few days are a write-off. The first real action doesn’t kick off until the morning of Tuesday, September 2nd, so you’re looking at a solid gap with no recommendations until then. After that, the size and energy come in, but conditions are fickle.

The water is a bit colder than normal for this time of year, sitting at 55°.

Wainui Bay Chalet is the only spot on the menu, and it’s a very consistent, exposed break that handles a south-southeast swell best.

Monday, August 31st is a total loss. Tiny little 2ft waves with a fresh cross-off breeze and very weak energy. Not worth getting wet.

Then Tuesday, September 1st rolls in with a massive pulse. The morning shows a solid 10ft swell from the south, with a moderate 13-second period and a massive amount of energy. The problem? It’s too big for this break. Cross-shore wind from the southwest doesn’t help. The afternoon drops to 6ft but turns cross-on and choppy. Not your day.

Now, Wednesday, September 2nd is the real standout. Morning brings a clean 6ft swell from the SSE with a 14-second period and strong energy. The wind is offshore from the northwest, a moderate breeze, and the conditions are clean. This is good for experienced surfers. Then the afternoon gets even better – glassy conditions, no wind, and a 6ft swell with a long 17-second period and very strong energy. That’s a proper groundswell, and it’s going to be absolutely clean. This is the best on offer, no question.

Thursday, September 3rd still has some fun options. A 4ft SSE swell in the morning with a moderate offshore wind and a clean 3ft in the afternoon. Good, but not the standout.

Friday, September 4th through Sunday, September 6th is a real lull. Tiny waves (1ft to 3ft), weak energy, and mostly ordinary conditions. Not worth rushing.

Monday, September 7th is a messy one. A 5ft swell in the morning is ruined by a fresh cross-shore, and the afternoon brings a 10ft swell with a cross-on wind and lumpy chop. Avoid.

Tuesday, September 8th is another massive day. A 15ft swell from the south with a 11-second period and enormous energy. But again, it’s too big for this break, and the cross-on wind in the afternoon makes it a mess. The morning is clean with a light wind, but that size is for experts only.

The rest of the second week (September 9th to 14th) is mostly poor. Small swells, poor winds, and marginal conditions. A few clean moments on the 10th and 13th mornings, but with very weak energy.

The final standout arrives on Tuesday, September 15th. A clean 6ft swell from the SSE with a very long 16-second period and strong energy. The morning has a light cross-off breeze from the NNW, making it clean. This is another excellent session for experienced surfers, though the afternoon goes cross-shore and messy. Mark this one in your calendar.

So, to sum it up: Wednesday, September 2nd is the absolute best bet, with glassy afternoon conditions and a solid groundswell. Tuesday, September 15th is a close second for a long-range, promising session. The rest is mostly waiting.

Rusty.
