Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, this is Rusty. Let’s have a look at what’s coming up for Nanwan Beach.

Gotta be straight with you: the next week or so is a bit of a grind. We’ve got solid swell running, but the wind is mostly a cross-off or cross breeze, so the waves are going to be there but not exactly perfect. The water temperature is about average for this time of year, so no surprises there.

The standout window is at the far end of the forecast, more than a week away, and it looks promising. Over the first few days, from Friday the 21st through the weekend, we’ve got a decent SW swell running 8 ft to 10 ft with a period of 9-10 seconds. The combined energy is strong, around 1617, but the wind is a fresh 30 km/h cross-off, so it’ll be bumpy and a bit of a wrestle. For the experienced guys, there’s something there, but it’s not the cleanest. The swell is above 8 ft on Friday, so that’s expert-only territory.

Saturday and Sunday, the swell drops slightly to 8 ft – 8 ft, still from the SW, and the wind eases off. Sunday afternoon looks the best of the early period with a light breeze and clean surf, and the energy is still moderate to strong at 862. It’ll be rideable but not glassy.

Then we hit the middle of the week, Monday the 24th through Tuesday the 25th. Monday gets messy with a moderate cross-shore and a fresh breeze, and the wave quality takes a hit. Tuesday the 25th brings a shift: a long-period E swell at 18 seconds rolls in, with combined energy jumping to 3590. That’s a powerful groundswell, but it’s coming straight from the east with a cross wind. At Nanwan, a long-period E swell can be tricky and might close out or break straight, so keep that in mind. The swell height is around 7 ft, so still solid.

From Wednesday the 26th into the 30th, things go quiet. The wind turns onshore or cross-onshore, the swell drops to 5 ft – 7 ft, and the combined energy falls to between 405 and 943. The scores are poor, and honestly, it looks like a blank run for quality surf. There’s a gap of several days here with no real recommendations until the very end of August.

Now, the real gold is on the 1st and 2nd of September. Tuesday the 1st, we’ve got a 10 ft SSW swell with a 10-second period, and the wind goes glassy in the morning – 5 km/h from the ESE. The combined energy is a huge 3461. That’s the best on offer, a true standout, but at 10 ft it’s for experienced surfers only. Wednesday the 2nd is similar: 8 ft SW swell, glassy in the morning and afternoon, combined energy around 2129. Two days of excellent, clean, powerful surf. These two days are the highlight of the whole 16-day window, no doubt.

After that, from Thursday the 3rd into the 5th of September, the swell eases back to 7 ft – 8 ft, the wind turns cross-shore, and the energy drops to moderate levels around 783 to 840. It’s still surfable but not in the same league.

So, to wrap it up: the first week is a mixed bag with the best early being Sunday afternoon. Then a quiet spell mid-week. Then a very promising, but more uncertain, standout at the start of September. If you can wait, the 1st and 2nd are the ones to circle on the calendar.

Rusty.
