The Lowdown
Alright you mob, ol' Rusty here. We've got a solid 16-day window for Wainui Beach – Stockroute, and let me tell you, it's a game of patience. The first week is a bit of a washout, but the second week? That's where the magic is brewing.
Right now, the water temp is sitting at 55.8°, which is a smidge cooler than usual for this time of year, but nothing too crazy.
The first real sign of life shows up on Wednesday morning, the 9th of September. We're looking at a 6.6 ft swell from the SSW, but it's a short-period, weak offering. The wind is light, but it's a cross-shore, so it's not going to be clean. The combined energy is moderate (952), but it's not a day to get excited about.
Then we get a bit of a gap. The next standout is looking like Saturday morning, the 12th of September. A clean 4.3 ft from the SSE with a moderate offshore wind from the WNW. The swell energy is moderate (389), and it's the first time we see a real "expect good surf conditions" vibe. It's not huge, but it'll be clean.
Now, hold onto your boards, because the real beauty is on Thursday morning, the 17th of September. We've got a 7.2 ft SSE groundswell with a long period of 14 seconds and combined energy of 1977 – that's strong wave energy. The wind is a light offshore from the north, making for glassy, clean conditions. This is excellent surf for experienced surfers. The long period will make for some proper lines, especially for a beach and reef setup like this. It's the clear standout of the whole forecast.
But wait, there's more. Saturday morning, the 19th of September, is another cracker. A 7.5 ft swell from the S, with a light offshore wind from the west. The energy is strong (1416), and the conditions are clean. Again, this is for the experienced crew – it's a big, powerful swell.
The takeaway? The first week is a write-off. The best of the best is Thursday the 17th, with Saturday the 19th as a close second. Don't bother paddling out before the 12th.
