Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, Rusty here again, but this time in feet and miles for the crew that thinks that way.

First thing: the next week and a half is a total dud. From now through the end of July, the wind is your enemy – cross or onshore, often fresh, and the water’s all lumpy. The swell comes in but it’s junk. Water temp is about 86°, normal for the season, so no story there.

The wave energy in that first week is moderate, but the quality is garbage. On the 19th and 20th of July, the swell pushes up to 8ft from the SSW, but with 18-22 mph cross-onshore winds, it’s a messy, blown-out mess. Too big for beginners, and for a beach and reef setup, it’s more of a kite-surfing day than a paddle one.

There’s a brief window from the 22nd to the 24th of July. The wind cleans up to cross-off, and the swell drops to 3ft to 5ft from the SW. The energy is weak (in the 100s), and the call is “surfable but very ordinary.” The morning of the 24th of July has light winds and a 3ft SW swell at 7 seconds – short period, no power, but it’s clean.

Then it goes flat for nearly a week, until the 29th of July.

Here’s the one guy you want to chase: the morning of the 29th of July. Glassy calm, a 3ft east swell with a 12-second period – that’s groundswell. The energy is solid moderate at 537. The wave comment says “expect good surf conditions.” This is your day. The break is a beach and reef, so with that long period, it might be a bit straight on the beach, but the reef could hold it together. Crowds are likely, so get there early.

The next day, the 30th of July, the wind screams 28-31 mph from the WNW, so don’t bother.

So, the standout is the 29th of July morning. It’s a long way out, so keep an eye on it. Everything else is a write-off.

Rusty.
