The Lowdown

Alright folks, Rusty here. Gotta be straight with you, the outlook for Wharariki Beach is a bit of a wild ride. We’ve got a lot of energy coming through, but the wind is going to be our biggest enemy. Let’s break it down.

We start off on Thursday, August 27th, with a bit of a whimper. Rain showers and a stiff cross-shore wind from the east at 22 mph are making a mess of the 4ft WNW swell. The combined energy is there (531), but it’s not pretty. The afternoon cleans up a little with a lighter cross-offshore breeze, but it’s still just a marginal call.

The weekend is a write-off for clean surfing. Friday, August 28th, sees a big jump in swell, hitting 13ft, but it’s accompanied by a near gale-force onshore wind. That’s a no-go. Saturday and Sunday follow the same pattern: big, powerful swell but with fresh to strong winds that will turn it into a washing machine. The water temperature is about average for this time of year here.

We get a bit of a reprieve on Monday, September 7th. The morning brings a clean 6ft groundswell from the west with a very long 16-second period, and a light breeze. The energy is pumping (1791), and conditions are clean. This is a serious window for experienced surfers who can handle the long-period lines. The swell direction from the west is a solid match for the break. But be warned, the afternoon gets messy again with a bigger swell and fresh wind.

The real standout, though, is Tuesday, September 8th. We’re looking at a solid 10ft groundswell from the west with that same long 15-second period, but the key is the wind: a light offshore breeze from the SSW in the morning. It’s shaping up for excellent conditions for expert surfers, with a massive 4618 combined energy. It’s a big, powerful groundswell, so this is for the experienced crew only. The afternoon still looks clean, but the wind swings around.

The following week, from September 9th, there’s more swell, but the wind is back up, making it tricky. The 10th of September offers another chance in the morning with a big 10ft swell and clean cross-offshore breeze, but it's another one for experts only.

Overall, the best bet is to keep your eyes on the morning of Monday the 7th and especially Tuesday the 8th of September. Those are the windows where the power of the ocean meets clean conditions. The rest of the time, it’s a battle with the wind.

Rusty, signing off.
