Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. We’ve got a bit of a mixed bag coming up for Nanwan Beach (South Bay). Conditions aren’t going to be firing straight away, with a fair bit of storm activity and wind to deal with. The water’s sitting at about 84°F, which is pretty much bang on average for this time of year, so no surprises there.

The first few days are a write-off, honestly. We’re looking at a gap until Monday the 17th August before there’s anything worth paddling out for. Thursday the 13th and Friday the 14th have poor surf with cross-off and cross winds, making a mess of things. Saturday the 15th is lumpy and rough with fresh cross-shore wind and a risk of thunderstorms. Sunday the 16th is still marginal.

Now, Monday the 17th August is where things start to turn. The afternoon session is the first real standout. We’ve got a 6ft swell from the SW, period of 8 seconds, with the wind dropping right off to just 3 mph. That’s clean, glassy conditions, and the combined swell energy is moderate at 493. It won’t be massive, but the quality will be there.

Tuesday the 18th August morning is another beauty. A light offshore breeze from the North at 6 mph, with clean 5ft SW swell at a 9-second period. This is perfect for a longboard or a funboard. The energy is moderate at 399. Crowds are often, so expect some company, but the conditions will be worth it.

We then hit another rough patch from Wednesday the 19th through Friday the 21st, with strong winds and poor conditions. Nothing to see there.

The long-range forecast shows some bigger, more powerful swell arriving around Saturday the 22nd August, but it’s coming straight onshore from the SSE at 6 mph. The swell hits 10ft from the SSW with a period of 10 seconds – that’s a lot of energy (1724), but with onshore wind, it’ll be a messy, blown-out mess. This one is for experts only if they’re desperate, and definitely too big for beginners.

Sunday the 23rd August looks better. A clean, 7ft SSW groundswell with a 10-second period and a cross-off wind from the West at 9 mph. Energy is moderate to strong at 753. The sets will have some punch, and it should be a fun, clean day for the intermediate crew.

Way out on Monday the 25th and Tuesday the 26th August, there’s a call for a very long-period E swell. On the 25th, we’re looking at 6ft from the SW, but the day after, the 26th, might be the real sleeper. That afternoon sees a 6ft swell from the East with a 13-second period, but it’s cross-shore wind with a lumpy chop, so it’s a bit of a gamble. The best bet from that window is Tuesday the 25th August morning, with a 6ft SW swell, fresh but clean cross-off winds, and strong energy (1348). That has potential if the winds hold.

Let’s be honest, the standout overall is Monday the 17th August afternoon. Perfect conditions for a clean, fun session. If you can wait, Tuesday the 18th morning is a close second.

Rusty.
