The Lowdown

Alright, it's Rusty here. Let's check out what's on the menu for the next couple of weeks.

First up, we're looking at a classic spot: Wainui Beach - Stockroute. It's a beach and reef setup that's super consistent and exposed to the SSE swell. The water temp is sitting at 55°F, which is a bit colder than normal for this time of year, so you'll be wanting that extra thick wetsuit.

The next few days are pretty quiet. We've got a bit of a lull with some small, poor surf conditions through the weekend. Sunday the 23rd is a write-off with tiny 2ft swell and a cross-off breeze. The gap in real quality surf lasts until Tuesday the 25th.

Tuesday morning the 25th is where things start to look up. There's a clean 3ft swell from the SSE with a nice 12-second period, and the wind is light offshore from the WNW. The energy is moderate (237), and the conditions are looking good. This is a solid bet for a morning session.

We get a bit of a pulse building through the end of the week. Thursday the 27th morning has a clean 3ft SSE swell with a long 16-second period and a gentle offshore breeze. The energy is ramping up to a strong (497). That long period groundswell will be drawing some nice lines, but it might be a bit straight for the beach section, so keep an eye on the reef.

Thursday afternoon is even better, with a 3ft SSE swell, still a long 17-second period, and a clean cross-off wind. The energy is up to 644 (strong). This is looking like a standout session for the advanced lads, with good shape and power.

Friday the 28th stays solid with 4ft swell and 15-second periods, but the wind is cross-off and the conditions are a bit marginal. The energy is still strong (540). It's good, but not as clean as Thursday.

The weekend drops off in size, and then we get a bit of a wild card on Monday the 31st of August. The swell jumps to 7ft, but it's a short-period 8-second SSW swell. The energy is very strong (794), but that short period means it's going to be a bit of a mess. The wind is cross-off, so it's not a total loss, but it's more for the experienced crew.

Now, hold on to your board. Tuesday the 1st of September is looking like the absolute best of the entire forecast. The morning session has a powerful 6ft SSE swell with a very long 15-second period. The wind is gentle and offshore from the NW, and the combined energy is a massive 1448 (very strong!). This is excellent, clean, powerful groundswell. The only caveat is that at 6ft, it's getting a bit big for the beginners, but for the advanced surfers, this is a proper day. The afternoon drops a bit to 5ft, still fantastic.

The following week is a mixed bag. There's a major pulse on Sunday the 6th of September with a huge 16ft SSW swell, but with a combined energy of 12709, the forecast is clear that it's too big for this break. That's a big pass for us. The conditions are clean, but that's a day for the experts only, and even then, it's likely more of a spectacle than a safe paddle.

The run ends on Monday the 7th of September afternoon with a 8ft SE swell, a 12-second period, and a gentle offshore wind. The energy is 1537 (very strong), and it's being called excellent for experienced surfers.

So, to wrap it up: the standout is Tuesday morning, the 1st of September. The other solid call is Thursday the 27th. The rest of the window is a mix of small lulls and big, potentially dangerous swells. Keep your eyes on the forecast, and don't be afraid to get out for those clean, offshore mornings.

Rusty.
