Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what Nanwan Beach has cookin' for us over the next couple of weeks. Gotta be straight with you – this forecast is a tough one. We've got a long, long dry spell before anything worth paddling out for shows up.

The first couple of weeks are a real struggle. For day after day, we're looking at tiny dribble – swells barely breaking 0.7ft, with periods so short they’ve got no push. The wind is mostly a cross-offshore from the NE, which at least keeps the water clean, but there's just no energy to work with. The combined wave energy is wandering around in the single digits, sometimes barely hitting 92 on the 19th of September, which is still laughably weak. Honestly, it's a write-off. You'd be better off finding something else to do.

But hold on. If you've got patience, things get interesting. After a gap of almost no surf of any note, the real story starts on the morning of Sunday the 27th of September. We finally see a pulse of proper groundswell roll in. That morning, a 6ft easterly swell with a very long 15-second period arrives, carrying a combined energy of 1449 – that’s a solid, moderate energy level. Now, a period that long at a beach and reef break like this can mean it breaks a little too straight, so you'll need to pick your peak. The wind is light and variable, bordering on cross, so it's not perfect, but it's surfable for those who know what they're doing.

The standout, the one you should circle on your calendar, is the afternoon of Sunday the 27th of September. That’s when the stars align. The swell picks up to a clean 7ft from the east, still with that dreamy 15-second period, and the wind goes totally glassy. That is about as clean as it gets. The combined energy cranks up to 2083, a solid moderate energy. The conditions are described as excellent for experienced surfers – and that's exactly right. At 7ft, this is solid, powerful stuff, not for the faint of heart. It's for the crew who can handle a proper wave.

If you miss that, the following day, Monday the 28th of September, holds strong. The swell jumps to a serious 10ft from the east, with the same 15-second period and the combined energy rocketing up to 3371 – that's strong energy. The wind is a light cross-offshore from the NNE, keeping the face clean. But again, this is big. Over 8ft, this is strictly for experts. A 10ft groundswell with that much push will be a handful, but for the right crew, it'll be absolutely pumping.

Remember, the water temp is sitting at 84°F, which is pretty average for this time of year, so a spring suit is all you'll need.

So, the verdict: it's a long, flat wait followed by a very promising, but sizeable, pulse. The Sunday afternoon is your best bet for the cleanest conditions on a manageable big-wave day.

Keep your eyes on the horizon.
