The Lowdown

G’day, Rusty here. Look, I’m gonna be straight with you—this sixteen-day stretch for Wharariki Beach is a bumpy ride, and for the first week, it’s pretty much a write-off unless you’re into punishment. The start is grim, but there are a couple of windows that will get the heart pumping, especially for the crew with some experience under their belt.

The first recommendation doesn’t show up until Saturday the 5th, and even that’s only marginal. The first week is hammered by strong to near-gale winds out of the west and southwest, whipping up a messy cross-shore chop. The swell is all over the place—big, energetic, but blown to bits. You’ll see the swell heights from 10ft to 13ft early on, with energy readings off the charts, but the conditions are just poor. It’s more of a kite-surfing show than a paddle session.

Then we get a bit of a reprieve. On Monday the 7th, the morning brings a clean, cross-off wind with a solid 13ft swell out of the west, period at 15 seconds. The energy is enormous. But here’s the thing: that’s too big for the average punter. It's expert territory only. The water temp is about average for this time of year.

The real standout, the one to circle on the calendar, is Thursday the 10th. The afternoon session is the pick of the whole outlook. You’ve got an 8ft west swell with a very long period of 19 seconds, bringing serious grunt and shape. The wind drops to a near-calm 5 km/h from the NNW, giving you glassy, cross-off conditions. The report says “exceptional surf conditions for expert surfers.” This is a groundswell with that long period, meaning it’ll be best if you’re hitting the reefs or points, as it might wall up a bit straight at a beach break. Crowds aren’t mentioned, so you might have it to yourself. Friday the 11th morning is also clean with a 6ft swell, but Thursday afternoon is the one.

After that, the second week falls away. Friday the 11th afternoon and Saturday the 12th have clean-ish cross-off winds, but the wind picks up again, and the quality drops to marginal. From Sunday the 13th onward, it’s back to poor conditions with fresh cross-shore winds and lumpy chop, with a few rainy days thrown in. The long-range stuff just never comes together.

So, to sum it up: the first week is a battle with the wind, and the second week fizzles. Your best bet is Thursday the 10th afternoon—cloudy skies, glassy wind, and a powerful, long-period west swell. That’s the one to chase if you’ve got the skill.

Rusty.
