Wharariki Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's coming our way over the next couple of weeks. It's a bit of a mixed bag, with some real gems hiding in the second week, so you'll want to pay attention.

First things first, the water temp is sitting about average for this time of year at 57°, so nothing wild there. The overall pattern kicks off with a bit of a dud, then a solid pulse of groundswell that's mainly for the experienced crew, and finally a sweet window of clean, manageable waves.

Right now, it’s pretty quiet. The first few days don't have much to offer, with a small, short-period 3ft swell on the 15th that’s got a marginal feel to it. That’s followed by a few days of strong winds and lumpy conditions. Nothing to get excited about.

Things change on the 17th of September. We’ve got a 8ft WNW swell building, but it’s short period (9 seconds) and the wind is strong. The wave energy is ramping up though (1078 combined energy). This isn't a beginner's session. By Thursday afternoon the swell jumps to 8ft, and by Friday morning the 18th, it’s a solid 8ft at 16 seconds from the west. That’s proper groundswell, with a massive 3067 energy reading. But here’s the thing—the wind is a strong cross-offshore, and at 8ft, it’s pushing into expert-only territory. This is when Wharariki Beach really comes alive for the big-wave crew. That long-period swell (over 15 seconds) will be lining up, but it’s going to be powerful and the sets will be wide apart. If you’re not experienced, stay on the sand and watch. The following days hold similar size, but the wind stays strong and the ocean is a mess.

Now, let's skip ahead to the standout window. If you can wait, the 23rd of September, Wednesday morning, is looking like the pick of the bunch. We’ve got a 8ft W swell with a very long 17-second period and, crucially, a light SSE offshore breeze coming through clean. The combined energy is still high (3104), but the conditions are described as "excellent for experienced surfers." This is big, clean, lined-up groundswell at Wharariki. It’s still big at over 8ft, so it’s for the chargers only. The crowds are listed as "never", so you might have it to yourself, but with that kind of size, you'll want to be confident.

Then, the next day, Thursday the 24th of September, is the best balance of the whole run. The swell drops just a touch to a very clean 6ft from the west, still with a superb 16-second period. The magic is the wind: glassy, from the southeast. Total flat calm. The combined energy is still a solid 1611, meaning plenty of push, but at 6ft it’s a much more manageable size for a strong intermediate. This is a true standout session.

The window closes with a smaller, glassy 3ft wave on the 25th and a few more clean days after that, but nothing that competes with that Thursday morning gold.

So, to sum it up: the first week is a washout or for experts only. The real highlight is Thursday the 24th of September at Wharariki Beach—that’s the one to circle on the calendar for clean, powerful, and accessible surf.

Rusty, signing off.
