Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down what’s on the table for the next couple of weeks. It’s a mixed bag of ups and downs, so pay attention to the windows.

The forecast starts off rough. Thursday the 20th and Friday the 21st are looking pretty average at best. We’ve got a solid 8ft to 10ft of SSW swell rolling in, but the wind is a problem – cross-shore and bumpy, making for messy conditions. The combined energy is moderate to strong (around 1166 to 1679), but the quality just isn’t there for a good session. You’ll be battling a cross-chop and the wind state is just not clean. Skip it.

The weekend isn’t much better. Saturday the 22nd and Sunday the 23rd stay in that same range, with 8ft to 8ft of SW swell. Winds are still cross-off, but there’s a lot of rain and lumpy chop around. The energy dips a bit (into the 800s to 1100s), but it’s still not what you’d call good surf. The crowd factor is likely to be an issue here too, often busy.

Now, Monday the 24th is where things start to look up. The morning has a clean 7ft of SW swell with light offshore winds from the west. The combined energy is moderate (801), but the conditions are clean. This is a good window for an intermediate surfer. The water temperature is about 84°F, which is normal for this time of year.

Tuesday the 25th is a bit of a wild card. The swell direction shifts to the east, with a 6ft, very long-period swell (17 seconds). That’s a groundswell, and it’s powerful – the combined energy jumps to 2161. However, the wind is cross-shore, and the period is so long it might break too straight for the beach break setup at Nanwan Beach. It’s a marginal call, but the energy is there.

The next few days, from Wednesday the 26th to Saturday the 29th, are a bit of a lull. The swell drops to 5ft to 6ft, and the wind is either cross-onshore or cross-shore, keeping the surf choppy and poor. The energy is low (in the 300s to 500s). Not worth paddling out.

Sunday the 30th is worth a mention. The afternoon has a 8ft SW swell with a true offshore wind from the north, 30 km/h. The combined energy is strong (1224) and the conditions are clean. This is a solid window for experienced surfers, as the swell is getting big. The wind is offshore, which is a major positive.

The first week of September is where the real standout sits. Monday the 1st is a bit messy, but then Tuesday the 2nd of September, the morning has a 8ft SW swell with clean, glassy cross-offshore winds from the west. The combined energy is moderate (1192), but the conditions are described as “very good.” This is your best bet for the whole forecast. The swell is solid, the wind is clean, and Nanwan Beach should be offering some good waves. It’s a bit big for beginners, but it’s a great window for intermediate to advanced surfers.

The window then fades out through the 3rd and 4th of September, with the swell dropping to 5ft and the winds staying light and clean. Good for a mellow session, but nothing to write home about.

So, the standout is the morning of Tuesday the 2nd of September. That’s the one to circle on your calendar. The rest is a bit of a wait for the right conditions to line up.

Rusty.
