Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let’s get into it. The forecast for Nanwan Beach (South Bay) is a wild ride, but we gotta be patient. The first week has some serious swell, but the wind is a total mess for most of it. The real standout is way out there.

Right off the bat, Wednesday morning, August 5th, we’ve got some real potential. The water’s a warm 85°, which is dead average for this time of year, so no surprises there. We’re looking at a solid 6ft easterly groundswell with a very long 17-second period, packing a massive 2207 energy reading. The wind is light and cross-offshore, so the setup looks clean for experienced surfers. That long period means the waves will have heaps of power and shape, but it’ll be lining up for a proper reef or point setup, not a beach break. This is a window for the crew who know what they’re doing.

The rest of the week and into the next is a write-off. Thursday the 6th drops to weak, junky swell, and from Friday the 7th all the way through the following Saturday, August 15th, it’s a tough stretch. The swell gets huge, hitting 10ft to 13ft, but the wind is howling from the west at 31 to 37 mph, making it dangerous and blown out. For a beach and reef setup, that’s more of a kite-surfing show than a paddle session. There’s a lot of energy out there (over 2700 at points), but it’s just too messy and big for this spot.

We hit a bit of a lull, but then we get a glimmer. Sunday, August 16th, the swell drops to a more manageable 6ft, the wind settles to a light breeze, and the conditions are labeled “good.” It’s still a cross-offshore wind, so it’s clean. The energy is moderate at 467, but it’s a step in the right direction.

Now, the real highlight is Thursday, August 20th. This is over two weeks out, so take it with a pinch of salt, but the models are lining up something special. We’ve got a 7ft groundswell from the south-southwest with a very long 13-second period and a massive 1821 energy reading. The wind is light and cross-offshore, making for glassy conditions. This is the one to circle on the calendar for experienced surfers. It’s a long way off, but if it holds, it’ll be the best session of the whole forecast.

So, to sum it up: the first couple of days have a narrow window for the pros, then a long, windy gap of almost two weeks, followed by a promising but distant swell on the 20th. Hang tight.
