The Lowdown
Hey, Rusty here. Alright, for this stretch of coast, we’re looking at a proper mixed bag. There’s a slow start – Sunday the 6th and Monday the 7th have barely a ripple, just tiny 1ft SSE swells with light offshores, nothing to get excited about. The real stuff kicks in from Tuesday the 8th, but it’s a wild ride.
The day to pencil in is the morning of Tuesday the 15th of September. That’s the standout. We’ve got a clean 5ft SSE swell rolling in with a long 13-second period, and a gentle offshore breeze from the WNW. Combined swell energy is moderate at 756. Wainui Bay Chalet should be serving up some nice shaped waves with that groundswell – sets will be a bit further apart, which makes paddling out easier. Crowds are possible, so get in early. The water’s sitting at about 56°F, which is just over a degree cooler than usual for this time of year – nothing crazy, just a bit nippy. The afternoon holds up too, with 4ft and still offshore – a solid day.
Before that, it gets pretty intense. From Tuesday the 8th through to Monday the 14th, the swell pumps up to 8ft to 13ft from the SSE, with combined energy readings in the thousands – 1938, 3901, even 9367 on the afternoon of the 13th. That’s very strong energy. The period’s all over the place – short on some days (8 seconds) and long on others (up to 15 seconds) – but the cross-shore winds and sheer size make it a messy, powerful beast. Experts only, if anyone. Honestly, with that kind of size and wind, it looks more like a kite-surfing zone than a paddle spot. Steer clear unless you’re seriously hardcore.
From Wednesday the 16th onward, it drops right back to tiny, ordinary surf. 1ft to 2ft swells, mostly clean but lacking any power. The morning of Saturday the 20th shows a bit of promise with a 2ft SSE swell, 16-second period, and moderate offshore, but it’s pretty small.
So, to sum it up: your best bet is Tuesday the 15th of September – clean, manageable, and fun. The rest is either way too big or way too small.
Rusty.
