Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for Nanwan Beach (South Bay). It’s a beach and reef setup, fairly consistent, and it loves a swell from the SE. The water’s sittin’ at a normal 84°F for this time of year, so nothing weird there.

Right off the bat, we’ve got a little window of surf this Friday afternoon, but honestly, it’s nothin’ to write home about. The swell’s coming in at 6ft from the SW with a short 8-second period, and the cross-off wind is blowin’ at 12 mph. The combined energy’s moderate at 510, but the conditions are marginal, so it’s more of a “maybe paddle out if you’re desperate” kind of deal. The rest of the weekend and into early next week is a write-off. Saturday and Sunday are poor – the swell drops to 4ft to 4ft, and the wind’s still cross-off or cross-shore. It’s not gonna be fun.

Monday afternoon on the 7th of September? Now that’s a glimmer. The swell’s only 3ft from the SW, but the wind goes glassy – a light NE at 3 mph. That’s a rare treat for clean conditions. The energy’s weak at 98, so it’s small and clean, but don’t expect any power. Could be a fun little session on a longboard if you’re keen.

Then we hit a dry spell. From Tuesday the 8th all the way through to Friday the 11th, it’s just poor surf. Swell drops to 2ft, then 1ft, and even a 0.7ft day with a 16-second period but no height. The energy’s in the double digits – weak. Not worth paddlin’ out.

Now, mark your calendar for Saturday the 12th of September. We’ve got a pulse of swell coming in at 8ft from the ESE, with a 9-second period. The combined energy jumps to 818 – that’s moderate to strong. But the wind is cross-off at 12 mph, and the conditions are described as marginal. It’s a bit of a gamble, but if you’re an experienced surfer, that’s the biggest swell of the window. It might be a bit too much for beginners at that size.

Sunday the 13th of September afternoon is the real standout. The swell drops to a more manageable 5ft from the SSW, period 9 seconds, and the wind goes glassy – calm, S at 3 mph. The energy’s still strong at 652, and the conditions are expected to be good. That’s clean, lined-up waves, and the glassy wind is a massive plus. That’s the session to aim for if you can only pick one.

After that, it’s back to small and poor. Monday the 14th has a long-period 14-second swell from the E, but only 2ft – the energy’s moderate at 296, but it’s just too small. The rest of the week into the 19th is all under 3ft, with weak energy and cross-off or cross-shore winds. Nothing to get excited about.

So, overall, we’ve got a couple of windows: the glassy Monday afternoon on the 7th for small clean fun, and the standout Sunday the 13th afternoon for the best combo of size and glassy conditions. The big Saturday the 12th is there for the experienced crew, but it’s a bit of a wild card. The second week dries right up, so don’t hold your breath.

Rusty out.
