Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on offer for Nanwan Beach (South Bay).

Honestly, it’s a tough stretch ahead. For the next several days, the surf is tiny or flat, and the wind is blowing cross-off from the northeast – not terrible for the surface, but there's simply no energy in the water. We’re looking at a long gap here. From Sunday the 13th right through to Friday the 18th, the swell is barely registering, with heights under 2ft and combined energy readings mostly in the single digits or low tens (78 is the highest, and that’s still weak). You’re not going to want to paddle out for that.

The water temperature is 84°F, about average for this time of year, so at least you won’t need a wetsuit while you’re standing on the sand watching.

Now, there is one tiny flicker of promise, but it’s a long way off. On Saturday the 19th of September, the afternoon shows a pulse of long-period groundswell from the east. Swell height hits 3ft, but the period is a very long 19 seconds, and the combined energy jumps to 473 (moderate). That’s a proper groundswell, and with a gentle breeze and clean conditions, it could offer a few lined-up waves. But it’s important to be real here: the spot is a beach and reef setup, and that kind of long-period east swell can be tricky – it might wrap in but could also break a bit straight. It’s also a fairly inconsistent break that gets crowded often, so if you’re keen, you’ll need to be sharp and early.

Beyond that Saturday afternoon, it goes back to the doldrums. We see nothing but tiny 0.3ft to 0.7ft slop right through to the end of the month. The wind does go glassy on Thursday the 24th, but there’s no swell to go with it.

So, the one standout is that Saturday the 19th afternoon session. Keep an eye on it, but don’t get your hopes too high. The rest of the period is a write-off for real surfing.

Rusty.
