The Lowdown
G’day, Rusty here. Let’s be straight with you—this 16-day stretch for the Wainui Beach – Stockroute zone is a bit of a slow burner, but there’s a serious payoff waiting if you’re patient. The first few days are pretty ordinary, with only small, weak surf and a lot of cross-onshore junk. Don’t get too excited about the start of the week; we’re looking at a few days of waiting before things start to wake up.
The first real sign of life shows on Tuesday morning, the 11th. We’ve got a 5ft SSW swell pushing in with a light cross-offshore breeze. The energy is only moderate (440), and it’s clean and surfable. It’s not a world-beater, but it’s the first decent wave of the period. After that, Wednesday and Thursday drop right back off into the ordinary category, with small, messy waves and onshore winds killing the vibe. Friday the 14th is a complete write-off—rain and a fresh cross-onshore breeze are making a mess of things.
Now, here’s where it gets interesting. Saturday the 15th afternoon is the first standout. The wind goes glassy, and that swell jumps up to 8ft from the southeast. The energy reading is strong (1341), and for the experienced crew, this is going to be firing. The wave comment says it’s excellent for experienced surfers, so if you’ve got the skills, this is your window. It’s a bit big for beginners, and the crowds can be a factor at times, so get out there if you can.
Sunday the 16th is still rideable, but it’s a step down with a bit more wind and chop. Then Monday the 17th is a hard no—the swell jumps to 12ft but the wind is strong and cross, making it a complete mess. This one’s for the kite crew, not the paddle surfers.
Now, pay attention. The big window starts Tuesday the 18th. We’ve got solid 12ft southerly swells, but the forecasting notes keep saying it’s too big for this break. That’s a warning—this is a heavy, powerful groundswell with long periods, and it’s going to be a serious, expert-only affair. The energy is huge, readings in the 3000s, but the conditions are mostly cross or cross-off, so it’s going to be raw. If you’re not a seasoned charger, stay well clear.
The real gem, the one you want to circle on the calendar, is Thursday the 20th morning. The swell is still a solid 10ft from the SSE, but the wind goes offshore and light. The energy is massive (3524), and the forecast says excellent conditions for experienced surfers. This is the standout. It’s big, it’s clean, and it’s going to have some proper power behind it. This is a serious, heavy wave, so it’s experts only. The crowd might be out, but the quality will be worth it.
After that, the swell eases but stays fun. Friday the 21st morning still has a decent 6ft SE swell with clean, cross-off winds—good for a solid session. Then we get another nice pulse on Saturday the 22nd morning, with 5ft ESE and an offshore breeze, though the period gets long, so it might be a bit straight at the beach; this spot is a beach and reef mix, so it should handle it. The following week, things mellow out. Sunday and Monday have some smaller, clean waves in the 4ft to 3ft range, but by Tuesday the 25th, it’s fading out to small and choppy.
So, in short: the first week is mostly a wait. The standout is Thursday the 20th morning, with Saturday the 15th afternoon as a great warm-up for the advanced crew. The middle of the month is for experts only. The water temp is about average for this time of year. Keep it salty.
