Nanarup Beach Surf Forecast and Surf Report

Grab the board, because this stretch of coast is about to wake up. The coming week has a bit of a slow and messy start, but there’s a clear building trend that’s got some proper grunt behind it. The main event looks like it’s shaping up for early September, so keep your eye on that window.

The first few days are a write-off, to be honest. Through the 28th and into the 29th, the wind is blowing the wrong way, mostly cross-onshore, and the swell is small—around 3ft to 3ft. The energy’s weak to moderate, sitting between 457 and 535 in the combined swell energy brackets. It’s choppy, it’s messy, and you’re not missing anything. There’s a bit more size pushing in on the afternoon of the 29th, jumping to 6ft, but it’s still cross-shore and lumpy, with moderate energy at 2132. Not worth the paddle out.

Things start to change on Sunday the 30th. The swell kicks up to 7ft from the SSW with a 18-second period, and the wind swings to a cross-offshore NE breeze at 12 mph. That’s a big jump in quality—clean lines, proper push. The combined energy is strong at 2854. This is the first real window where it starts to feel like a proper surf. Monday the 31st drops a little to 5ft, but with a clean cross-offshore wind from the west, it’s still rideable. The energy is moderate at 1234. From there, we drift through some average days, with the 2nd seeing a return to 6-6ft with clean conditions, but nothing that’s firing on all cylinders.

Now, the standout. Thursday the 3rd of September. The morning has 8ft of SSW swell, but the wind is light and cross-shore, making it a bit ragged. But the afternoon is where it’s at: the wind drops to nearly nothing—a glassy NNW breeze at 3 mph. The swell settles to 6ft, still at a 14-second period. That’s a clean, powerful, proper session. The combined energy is strong at 1663. This is the one. Mark it down.

Friday the 4th is also worth a mention. The morning has 7ft with clean cross-offshore wind, and the afternoon pushes back up to 8ft with a 15-second period. Combined energy hits 2982. It’s big and clean, but it’s edging into expert territory. If you’re not confident, this one might be a bit much. Remember, over 8ft is only for the crew who know what they’re doing. The wind stays clean through Friday afternoon, but Saturday the 5th brings a fresh breeze and a strong cross-shore mess, so that window closes fast.

After that, we go quiet again. The swell drops to 5ft on the 6th, but the wind is cross-shore and messy. The 7th is tiny, down to 2ft, and not worth your time. Then, look ahead. Tuesday the 8th has a glassy morning with a 5ft SSW swell, and the 9th has a 6ft swell with a proper offshore wind—moderate and clean, with combined energy of 1656. That’s another solid window. And then the 11th of September has a clean, glassy morning with 6ft at a 17-second period. That’s a long-period groundswell, so it’ll have some serious push and better shape. Combined energy is 1811.

Now, for the spot itself. Nanarup Beach is a consistent spot, but it’s a beach break. All this swell is coming from the SSW, which is spot on for the exposure here. The water is running at 63°, which is a touch warmer than average for this time of year—nothing crazy, but you won’t be freezing. Being a beach break, these long-period swells—over 15 seconds—can sometimes break a bit too straight and close out. It’s not ideal, but when the wind is clean and glassy like it is on the 3rd and 8th, it can still be world-class. Just be ready for the set waves to be a bit more walled-up.

Crowds are only “sometimes” an issue here, so you shouldn’t be fighting for every wave, especially on the standout days. Because it’s a beach break, and when the swell gets over 8ft with that strong cross-shore wind, it might actually look more fun for the kite crowd than for paddle surfers. But those clean windows are pure gold.

So, keep it simple. The next few days are junk. Wait for Sunday the 30th for the first clean, decent push. The best on offer is the afternoon of Thursday the 3rd—glassy, strong, and clean. Tuesday the 8th and the morning of the 11th are also promising, but they’re further out, so don’t lock those in yet. Keep it on the radar.

Stay stoked.

Rusty.
