Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s cooking at Nanwan Beach.

The next week and a half is a real mixed bag. We’ve got a cracking start, but then Mother Nature turns the dial up and things get messy. The good news is, after the storm passes, the tail end of the outlook looks solid again.

The water is sitting at a warm 85°, which is about average for the time of year, so no surprises there.

The standout is Tuesday the 4th. We’re looking at a clean, long-period groundswell from the East, coming in at 4 ft to 5 ft. The period is a very long 16 seconds, so these waves have real push and shape. The wind is a gentle cross-off breeze from the NE, keeping the faces clean. The combined energy is moderate at 904, building to 1190. This is the pick of the bunch for the whole window – great conditions for an intermediate surfer.

Wednesday the 5th is a close second. The swell builds to 6 ft from the East with a 17-second period, and the energy jumps right up to 2207. The wind switches to a light WNW cross-off. This is excellent surf, but at 6 ft, it’s pushing into the bigger end for a beach break, so it’s best for experienced surfers. It’s still going to be really good.

Then things go sideways. From Thursday the 6th right through to about Tuesday the 12th, the wind cranks up from the west and southwest, hitting 25-31 mph. The swell gets big, well over 8 ft, and the period drops to a short and choppy 6-8 seconds. This is going to be a washing machine. The surf quality is poor, and with those strong onshore winds, this setup looks way more interesting for kite surfing than paddle surfing. The combined energy is high, but it’s all wind and no shape.

The storm starts to ease on Thursday the 13th of August. The swell drops to 8 ft from the SW, and the wind backs off to 9 mph. The period stretches back to 11 seconds, and the energy is moderate at 1715. The conditions clean up into excellent surf for experienced surfers again.

Friday the 14th of August is another solid day. The swell holds at 8 ft from the SW, with a light WNW offshore breeze. The 11-second period gives it good form. This is a strong finish to the run.

After that, the swell slowly fades through the weekend and into the next week. The conditions stay clean but the energy drops off, and by Monday the 17th, the wind turns onshore again, killing the quality.

So, bottom line: get out there Tuesday the 4th and Wednesday the 5th for the best waves. The second week has a promising window on Thursday the 13th and Friday the 14th, but it’s a bit further out, so keep an eye on it.

Rusty.
