The Lowdown
Hey, Rusty here. Looking at Wainui Beach – Stockroute, it’s a slow start but there’s some real heavy water coming for the big-wave crew. Water temp is around 55°F, which feels a bit cooler than normal.
First chance is Monday 31 August morning – little waves around 2ft from the SSE, with the wind offshore from the WNW at 15 mph. The swell period is a long 17 seconds, so it’s groundswell, but the energy is moderate (275). Nothing to write home about.
Tuesday 1 September morning brings the first big push: 8ft from the S, period 12 seconds, and energy through the roof (3467). That’s strong. But the wind is cross-off from the SW at 15 mph, and conditions are questionable. Over 8ft, this is only for the experienced. Afternoon drops to about 6ft from the SSE, but cross-shore wind messes with it.
The standout is Wednesday 2 September morning. Swell at 6ft from the SSE, period 14 seconds, and a sweet offshore wind from the WNW at 9 mph. Energy is strong (1589), and the conditions are excellent. The swell direction is spot on, and the offshores will give you proper clean lines. This is your session.
Thursday 3 September morning still has 4ft from the SSE, with offshore NW wind at 15 mph and clean conditions. Energy is moderate (409). Fun but not the best.
Then it goes flat from Friday 4 September all the way through to Monday 7 September – tiny dribbles, nothing worth paddling for.
Tuesday 8 September morning surprises with 6ft from the SSW, period a short 8 seconds, but the wind is glassy – WNW at 3 mph. Dead calm. Energy is moderate (579), and the conditions are very good. Glassy surf at that size is a gift.
The last big one hits Sunday 13 September morning: 10ft from the SSW, period 10 seconds, energy at 2955. Wind is light from the W, cross-off, clean. Experts only. The afternoon swells to 12ft but it’s flagged as too big for the break with cross-onshore wind.
So, if I had to pick, it’s Wednesday 2 September morning. If that doesn’t work, Tuesday 8 September morning’s glassy conditions are a worthy second.
Rusty.
