Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the menu for Nanwan Beach (South Bay) over the next couple of weeks.

Right off the bat, it's a bit of a slow start. The first several days are looking pretty grim with small, weak swell and messy conditions. We're stuck with a long run of poor surf through Tuesday the 10th and beyond. The waves are tiny, around 2 ft to 3 ft, with a short period making for weak, crumbly surf. The wind is mostly a cross-offshore, but the swell just isn't there to make anything of it.

We finally see a pulse of life come in on Monday the 14th. The swell picks up to 4 ft from the SSW, and the energy starts to build. By Monday afternoon, we get a light offshore wind from the NNW, making for clean conditions. The real standout of this whole forecast comes on Tuesday the 15th. The afternoon looks like the pick of the bunch with a solid 6 ft SSW swell (with moderate wave energy around 807) and clean conditions thanks to a light north wind. This is the best on offer for the first week.

The swell builds further into Wednesday the 16th, hitting 8 ft from the SW, but the wind picks up too, getting fresh from the NE. That's a lot of power for a beach and reef setup, and with that strong breeze, it's going to be a bumpy, challenging session. Probably more for the experienced crew or maybe even the kite surfers. The energy is strong (1682), but the quality is marginal.

After that, the swell drops back down through the end of the week and into the weekend, with the waves fading from 6 ft down to nothing. The wind stays onshore, so it's back to the poor surf.

Now, the real interesting window is way out there, on the 22nd of September. The forecast shows a completely different picture. A clean 5 ft to 5 ft swell from the east arrives with a very long period of 15 seconds. This is groundswell energy, and it packs a punch (combined energy of 900 to 1005). The real kicker is the wind: glassy conditions in the morning, turning to a light offshore breeze in the afternoon. This is a long-range call, so it's a promising but less certain one. For a beach break, that long period can make the waves break a bit straight, but with that wind and size, it’s a very exciting prospect for Nanwan.

Water temp is sitting at 84°F, which is bang on average for this time of year, so no surprises there.

Rusty.
