Alright, Rusty here, let’s take a look at what’s coming down the line for Wharariki Beach.
First up, we’ve got a bit of a wait. The good stuff doesn’t kick in until Friday the 10th. Water temp is 59°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.
The standout window is Friday afternoon. Glassy conditions, light ESE breeze at 3 mph, and a clean 4 ft west swell with a solid 16-second period. That’s groundswell with some proper push, and the combined energy is moderate (605). It’s gonna be smooth, lined-up, and all yours with the crowds never being an issue here.
Saturday the 11th and Sunday the 12th are more average. The swell stays around 3 ft to 4 ft from the west, but the wind goes cross-shore, which puts a bit of a ruffle on the surface. The energy is still there, but it’s not the same clean dance as Friday.
Monday the 13th is ugly. Strong onshore winds and a jumpy little windswell. Not worth paddling out.
Tuesday the 14th and Wednesday the 15th see a big spike in swell, hitting 8 ft on Wednesday morning with a very long 17-second period. But the wind is onshore and lumpy, so that raw power is messy. The energy is through the roof (4039 for Wednesday morning), but it’s for experts only and the wind is ruining it.
The next true stand-out day is Sunday the 19th. That’s the one to circle. Glassy conditions, an ENE breeze at 3 mph, and a clean 6 ft west swell with a 16-second period. The energy is strong (1651), and it’s going to be excellent for experienced surfers. This is proper groundswell with good shape, and the clean conditions will make it a ripper.
Monday the 20th morning is also excellent glassy conditions and 6 ft west swell, but by afternoon the wind swings onshore and the period drops to a short 7 seconds, turning it into a bit of a mess.
After that, it tails off through the week with smaller, cleaner waves for the patient surfer. The morning of Friday the 24th and Saturday the 25th bring back some size, around 7 ft to 7 ft from the WNW, and Saturday afternoon the 25th is looking glassy and clean again with a 16-second west swell and strong energy (2059). That’s another one for the experienced crew, and it’s promising but a bit further out, so keep an eye on it.
So to wrap it up, the best windows are Friday the 10th afternoon for clean 4 ft surf, Sunday the 19th for punchy 6 ft glass, and Saturday the 25th for another solid 7 ft clean swell. There’s plenty of other options, but those are the real beauties.
Stay stoked.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Wharariki Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
