Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Nanwan Beach (South Bay). To be honest, the next couple of weeks are a real mixed bag – a lot of poor conditions to wade through before we get a glimmer of something decent.

The water temp is sitting at a warm 85°F and the anomaly is 0.9°F, so it’s pretty much bang on average for this time of year, a nice stable bath.

The first week is a write-off. You’re looking at small, weak swells with barely any energy (51) and constant cross-offshore winds. The wave heights are tiny, around 1ft to 2ft, and with a short period of 7 seconds, it’s just not worth paddling out for. We’ve got a solid gap of poor surf from Wednesday the 22nd all the way through to Sunday the 27th. Don’t bother.

Things get interesting, but dangerous, on the 28th of July. We see a big jump in swell size and energy. An 12ft swell from the East with a nice 11-second period is pushing in, and the wind is clean and cross-offshore. The energy is massive (2734). However, the swell is predicted to be too big for this break – that’s expert territory only, and even then, it’s a risk. That same energy runs into the 29th and 30th, but the wind swings around and gets messy, creating a lot of chop.

The real standout, the one you’ve been waiting for, is the 5th of August. Now, this is a long way out, so treat it as a promising but uncertain prospect. The forecast shows a big, powerful SSW groundswell hitting. We’re talking 15ft to 18ft with a solid 10-11 second period. The energy readings are insane (3715 on the morning, 7856 on the afternoon). The wind is clean and cross-offshore. This is proper, heavy, big-wave surf. But again, at these sizes, it’s too big for beginners and only for experienced, well-equipped surfers. The 4th of August also has some potential with 8ft waves and clean wind, but it’s a step down in energy.

After that, the 6th of August drops back to a more manageable 8ft to 10ft, still clean, but the juice is gone. For the rest of the run, it’s back to messy, wind-affected slop until the 6th, where things get clean again but the swell is dropping.

So, the only real window of fire is the 4th and 5th of August. The 5th is the true, big-wave standout if you’ve got the stones for it. The rest of the time, you’re better off on the beach with a cold one.

Rusty.
