Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what’s ahead for Nanwan Beach (South Bay). Let's be real with each other; this outlook is a long grind with one very specific, very promising window. Strap in.

The next couple of weeks are a proper mixed bag. We’ve got plenty of swell energy rolling in, but the wind and weather are just not playing ball for the most part. The water temp sits at a balmy 84°, pretty much bang on average for this time of year – no surprises there.

The pattern kicks off with a solid chunk of swell from the 25th of August right through the start of September, but it’s all served up with a side of risk t'storms and strong, cross-off winds. The wave heights stay in the 6ft to 8ft range, and the combined swell energy is mostly moderate to strong, but the quality is just “poor surf conditions.” You're paddling into chop and lumpy lines. Not the kind of session you write home about.

We hit a real dry spell from the morning of the 30th of August all the way through to the 4th of September. The energy drops off a cliff. The waves get small and weak. Honestly, not worth getting wet.

However, there is one standout session that saves the entire forecast. Mark your calendars for Tuesday, the 1st of September. The afternoon brings a golden moment: absolutely glassy conditions, an 8ft SSW groundswell rolling in with a very long 11-second period. The combined swell energy surges, promising power and shape. This is a bigger swell, over the 8ft mark, so this is strictly for the experienced crew. The swell direction (SSW) matches up perfectly with what the break wants, and that glassy wind means the face will be a mirror. For the experts, this is the only window in the whole 16-day run that delivers.

After that brief perfection, the surf fades fast. By mid-week, we’re back to small, weak slop with onshore winds. There’s a little flare-up on the 4th of September with a 7ft W swell, glassy wind, and “expect good surf conditions,” but with a short 6-second period, it’ll be a bit disorganised and fat. A less exciting, more session-filler kind of wave.

So, the takeaway is simple: ignore the noise and the long, dusty middle section. Set your sights on the 1st of September and pray that long-range promise holds. For the rest of it? Take a walk, tune the quiver, and wait for that glassy day.

Rusty.
