Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, Rusty here again, giving it to you in feet and Fahrenheit.

Let's be real, Nanwan Beach (South Bay) is going through a rough patch. From now through the 14th of September, it’s flat to weak. We’re talking ankle-snappers and onshores. Not a single session worth getting wet for. It’s a long stretch of nothing.

But hang tight, because it all changes around the 15th of September. Tuesday the 15th, we see a southwest swell start to push in. It’s around 4ft in the morning, building to nearly 6ft in the afternoon with a 13-second period. That’s proper groundswell, and the energy reading hits 976 (moderate). The wind goes clean and offshore from the west. This is where it starts to get interesting.

Now the real standout, the one you've been waiting for, is Wednesday the 16th and Thursday the 17th of September. Wednesday morning we’ve got a solid 8ft swell from the southwest, and by the afternoon it’s 10ft with a 14-second period. Energy readings are at 2485 and 2803 – that's strong wave energy. Winds are clean and cross-offshore from the northeast. At 8 to 10ft, this is strictly for experienced surfers. The long period means better shaped waves, but at a beach-and-reef break, it can wall up and close out. Expect serious power.

Thursday the 17th is the big one. We’re looking at 11 to 12ft from the west-southwest with a very long 15-second period. The combined energy is massive – 5767 and 5301 – very strong wave energy. The wind stays cross-offshore and clean. The catch is, the forecast says this might be too big for this break. For any surfer, over 8ft is expert territory, and at 12ft, this could be more of a tow-in day. If you're not a seasoned charger, stay on the beach.

After that, the swell backs down through the 18th into the weekend, holding in the 4ft to 8ft range with cleaner conditions. It’s not the peak, but it’s a lot better than the first week.

Water temp is 84°, which is right about average for the time of year, so no surprises there.

Bottom line: the first week is a dud. The real action is on the 16th and 17th of September, but it’s big, powerful, and dangerous – experts only. Keep your eyes on the charts.

Rusty.
