The Lowdown
Alright, this is Rusty here, and I’ve got a look at what’s shaping up for Wharariki Beach. Let’s get straight into it.
Alright, Wharariki Beach, it’s a bit of a mixed bag coming up. The water temp is sitting pretty average for this time of year, nothing wild there. The swell direction is coming from the west, which is exactly what this exposed spot wants to see. But the wind is gonna be our main character for a while.
We kick things off on Wednesday the 9th. It’s a bit of a slow start, with a small 3ft west swell, but the cross-shore wind is making it choppy and messy. The combined energy is weak (259), so it’s not really worth the paddle out. Thursday morning the 10th is still a bit tricky, but then Thursday afternoon rolls in and it’s like a different world. The wind goes offshore, light and gentle, and we get a clean 3ft west swell with a long 16-second period. The energy jumps up (1411), and it’s clean as a whistle. That’s your window for a nice, easy session – perfect for intermediates.
Now, Friday the 11th is where things get a bit more serious. The swell is up to 8ft in the morning, and the wind is cross-offshore but strong. That’s getting into the bigger stuff, and the energy is huge (4342). By Friday afternoon, it’s hitting 10ft, and while the conditions are clean, that’s expert territory. This spot is exposed, so that northwest swell is gonna be firing straight in. Saturday the 12th stays big, with 10ft waves and a ton of energy (5914). It’s just too much for most of us, and the wind is howling again.
After that, the size drops a bit over Sunday and Monday, but the wind is still a problem. It’s cross-offshore and strong, making it hard to get clean waves. The swell is there, but the quality is shot. The best bet in that stretch is probably Sunday morning the 13th, with a 5ft swell and clean conditions, but the energy is still high (3037) and the wind is fresh.
Looking further out, the second week is a real mixed bag of big swell and howling winds. By Friday the 18th, we’re seeing 12ft waves with massive energy (7360), but the wind is just too strong. It’s a washing machine out there. The pattern continues into the third week, with huge swell, but the wind is consistently cross or cross-offshore and strong. It feels like it’s going to be a stretch of days where it’s just too big or too windy for a decent paddle. You’d be looking at a kite session more than a surf session on a lot of those days.
So, the standout is absolutely Thursday afternoon the 10th. It’s the only period where the stars align: small, clean, offshore, and manageable. If you can get out then, that’s the one. The rest of the window is either too big, too windy, or both. It’s a classic case of the ocean saying, “Not today, mate.”
Rusty.
