The Lowdown

Alright, Rusty here. Let’s talk about this stretch of coast.

We’ve got a bit of a mixed bag coming up, but there’s some real gold hiding in the second week if you’ve got the patience. The first few days offer some fun, workable waves, but the real standout is a day that’s a week and a half away. Don’t expect much glassy perfection straight out of the gate, but the end of the run looks absolutely mint for the experienced crew.

Tuesday morning you can get onto it at Wainui Beach - Stockroute. Swell is a clean 5ft from the SSW, with a light offshore breeze. The combined energy is moderate at 430. It’s solid, clean, and a good start. The afternoon sees the wind swing and pick up, making it a bit of a battle, but the morning window is worth it. The water temp is about average for this time of year, nothing to write home about.

Wednesday morning is glassy, but the swell drops right off to a weak 3ft from the SE. The energy is low at 138. It’s surfable but very ordinary. After that, Thursday through Saturday morning are a write-off – wind is onshore or cross-shore, and the quality is poor. Saturday morning actually sees a jump in size to 8ft from the ESE, but with a fresh 19 mph cross-onshore wind, it’s a lumpy, messy mess. That’s kite-surfing territory, not for the paddle crew.

Sunday and Monday keep the size up over 5ft, but the wind is strong and gusty, with a lot of chop. Not the time to be a hero.

Now, here’s the one that gets the blood pumping. Friday morning, the 21st of August. That’s the standout. The swell is 6ft from the SSE, with a massive 17-second period – that’s deep, long-range groundswell. The wind is glassy, dead calm from the west. The combined energy is strong at 1635. This is excellent surf for experienced surfers. It’s a reef and beach setup, so that long period will bend beautifully around the point. The crowd profile is “sometimes,” so you might have some company, but with conditions this good, it’ll be worth it.

Saturday the 22nd is still very good – 4ft from the SSE, 12-second period, and a clean offshore breeze. Expect very good surf. Sunday the 23rd is smaller but glassy again in the morning.

Looking way out, Monday the 24th morning looks promising with a glassy 5ft, 14-second swell from the SSE. Energy is moderate-strong at 947. That’s another one to circle. After that, the wind turns nasty again and the last few days of the run are a write-off.

So, the takeaway? The first week is patchy, but it’s not a total loss. The real gem is that Friday the 21st morning – that’s the one to book a sickie for. The Saturday after is also a solid runner-up. The rest is just filler.

Rusty.
