The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks at Wainui Beach - Stockroute.
Straight up, the first few days are pretty flat. We’re talking Monday and Tuesday with barely a bump – tiny little 0.7ft to 1.0ft pulses that just won’t do anything. You’d be better off waxing your board and checking the tide pools.
The first real sign of life shows up on Wednesday morning, 9 September. It’s only a 4ft swell from the SE with a short 8-second period and weak wave energy (192), but the air’s clear and the wind is light. It’s surfable, but it’s ordinary. Nothing to get excited about.
Thursday and Friday stay small and messy. That Friday afternoon, 11 September, sees a jump to 8ft from the S, but the wind swings cross-on and it’s choppy as hell. The energy is ramping up (1305), but the quality is poor.
Now, Sunday morning, 13 September – that’s the standout. This is where it gets proper. We’ve got a solid 7ft swell rolling in from the SSE with a long 16-second period. That’s groundswell energy, folks. The combined energy is cranking at 2582, which is strong, and with a light WSW breeze keeping it clean, this is excellent surf for experienced surfers. This is too big for beginners, but for the crew who know what they’re doing, this is the pick of the whole run. The offshore wind direction here at Stockroute is WNW, so that light WSW air is actually a nice cross-off, which will hold the face open.
Monday morning, 14 September, is still firing with a 6ft SSE groundswell (14-second period) and a clean NW offshore. Energy is still strong at 1307. Another excellent session for the advanced crew.
After that, things drop off fast. The second week is a bit of a write-off. There’s a small, clean window on Tuesday morning, 15 September, with 3ft from the SSE and a light offshore, but it’s just small and average. The rest of the week is a mix of tiny swell, onshore wind, and rain. The last glimmer is Monday, 21 September, with a 4ft NE swell but a short 7-second period and moderate cross-off wind. Not worth rearranging your day for.
Overall, if you can get out on Sunday the 13th or Monday the 14th, you’ll score. The rest of the period is mostly small and messy, with a few long gaps of nothing much at all.
