Nanwan Beach (South Bay) Surf Forecast and Surf Report

G'day, Rusty here. Let's have a look at what's cookin' for Nanwan Beach (South Bay) over the next couple of weeks. It's a bit of a mixed bag, so we gotta pick our moments. The water temp is bang on average for this time of year at 84°F, so no surprises there.

Right off the bat, the first surf worth paddling out for is Sunday afternoon, the 16th. We've got a 7ft SW swell rolling in, with a period of 8 seconds. The wind is a cross-offshore from the W at 12 mph, so it'll be clean enough. The combined energy is moderate, sitting at 694. It's not a standout, but it's something to get wet for.

Monday the 17th is a strange one. The morning is a write-off with a messy cross-shore, but Monday afternoon turns glassy with zero wind from the E. The swell drops to 5ft from the SW, but that glassy surface makes it a genuine option. It won't be big, but for a clean session, that's your best bet early on.

From Tuesday the 18th, things go quiet. We're looking at a string of days with poor conditions, strong winds, and messy surf. Honestly, from Tuesday morning right through to Sunday the 24th, it's mostly poor or marginal at best. There are a couple of calls on Friday the 21st afternoon and Saturday the 22nd where the swell picks back up to around 7ft to 7ft, but the wind is never quite right, leaving it lumpy or crossed up. It's a long, frustrating gap with no real green light.

Now, here's where it gets interesting. On Tuesday the 25th, we see a shift. The afternoon session has a tiny 2ft swell, but it's from the E with a very long period of 15 seconds. The wind is cross-off from the W, and the energy is moderate at 451. The comment says "expect good surf conditions." That long-period groundswell hitting a beach and reef setup can be tricky—it might break a bit straight—but if you can find a bank, those 15-second lines will have some push.

Thursday the 27th is the real standout in the second week. Morning and afternoon both show clean, cross-off winds from the W around 12 to 16 mph, with a 5ft to 5ft E swell. The period is a very long 14 seconds, and the energy jumps to a strong 1309 and 1192. That's serious power for the size. The swell direction from the E is a good match for the optimum SE direction, so it's lining up nicely. Just keep in mind that long-period E swell at a beach break can be a bit straight. It's probably best for the more experienced crew.

Friday the 28th holds similar clean conditions with a smaller 4ft to 4ft E swell and the same long period. It's a nice run, but not as powerful as Thursday.

The last few days of August get messy again. Saturday the 29th has a 8ft SSW swell, but the wind is a cross-shore from the ENE at 16 mph, making it rough. That's borderline too big for beginners anyway. Sunday and Monday stay average.

If you're looking for the best bang for your buck, circle Thursday the 27th. That's the one with the most power, cleanest wind, and a swell that's actually pointing in the right direction. The Tuesday 25th afternoon glass-off is a dark horse for a sneaky, clean session on that tiny E groundswell.

That's the story from here. Keep your eye on the horizon.
