Wharariki Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s dig into what’s cookin’ for the next couple of weeks.

First off, the water temp is sittin’ around 57°F, which is pretty much bang on average for this time of year, so no wetsuit surprises there.

Right now, we’ve got a bit of a gap before anything truly decent shows up. The surf kicks off with a bang, but it’s a bang that’s gonna rattle your teeth. From the 4th of September right through the 6th, we’re lookin’ at a solid, but messy, 10ft to 12ft swell pouring in from the WNW. The problem? The wind is a complete mess – near gale-force cross and cross-on conditions. The wave energy is massive (anywhere from 2378 up to a thumping 5211), but it’s all chop and no shape. Honestly, for a beach break like Wharariki Beach, this setup looks way more interesting for kite surfers than paddle surfers. The 5th of September Saturday morning has a moment with a cleaner cross-off breeze and a 10ft W swell (3652 energy), but it’s flagged as too big for the break. Keep the board in the car for that one.

Then we hit a real lull. From the 7th through the 10th, we’re scraping the bottom of the barrel with small, weak swell (4ft to 5ft) and marginal conditions. The wind is all over the place, and the energy drops into the low hundreds. It’s a proper flat spell.

Now, hold onto your leash, because the 11th of September Friday is a standout, but it’s a tricky one. The morning delivers a clean 12ft swell from the west with a very long 19-second period (9009 energy), and the wind is a clean cross-off. The afternoon? Absolute magic – glassy conditions with the same 12ft W swell (8778 energy). This is a big, powerful, clean groundswell. But here’s the rub: it’s flagged as *too big for this break*. With that kind of size and period, it’s going to be a heaving, powerful beast, strictly for experts only. The long period (over 15 seconds) means it’ll be fat and straight at a beach break, so don’t expect perfect peaks. It’s a serious, intimidating ocean.

The 12th and 13th see a drop in size but a return of strong, clean offshore winds (W/SW) that will keep the surface clean. The swell hangs around 8ft to 10ft (2729 to 5120 energy), but the wind is a howling near-gale, making it a tough paddle.

The real gem of the whole forecast, the one that’ll get the local crew frothing, is the 14th of September Monday morning. We get a smaller, clean 4ft west swell (1201 energy) with a 16-second period, and the wind is a gentle offshore from the south. That’s 4ft of clean, lined-up, glassy groundswell. It’s flagged as excellent for experienced surfers, and with that light offshore wind, it’s going to be a dream. The 16th of September Wednesday morning is another solid option – a clean 8ft west swell (1192 energy) with a light cross-off breeze. That’s a bit more size, still clean, and more forgiving than the 11th.

After the 16th, the energy fades fast. The 17th and 18th are back to messy, small, or blown-out junk. The 19th is a complete write-off.

So, the one to circle on the calendar is Monday, 14th September. Wharariki Beach is exposed to the west, and that 4ft W swell with a gentle offshore S wind is gonna be pure, clean, lined-up bliss. The 11th is a monster, but only for the brave. The 16th is a solid, clean runner-up.

Stay stoked.
Rusty.
