Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, Rusty here, and let’s break down what we’re looking at for Nanwan Beach over the next couple of weeks.

First things first, the opening run is a total dud. Tiny waves and messy wind – don’t bother for the first four days or so. There’s a definite gap at the start with no surf worth mentioning.

Things wake up on Monday, the 3rd of August. That morning brings some waist-to-chest high east swell, about 2 feet with a very long 16-second period, and the combined energy is moderate (324). It’s a start. But the real standout is Monday afternoon. Glassy conditions, light southerly wind, the swell holding at a clean 3 feet from the east, and the combined energy hits a solid moderate (461). That’s the best session of the first part of the week – clean, glassy, and plenty of fun.

Tuesday the 4th of August is another big call. Morning sees 5 feet of east swell with a 16-second period, a light WNW cross-off breeze, and combined energy sitting at 1222 – that’s strong. It’s clean and has some punch. By afternoon it bumps to 5 feet with a 17-second period and energy at 1575, still clean. This is excellent for experienced surfers, though at over 5 feet it’s pushing it for beginners. The long period might make it a bit straight on the beach break, so watch your positioning.

Wednesday the 5th of August holds that east groundswell solid – 7 feet in the morning, up to 7 feet in the afternoon, with that very long 18-second period. Combined energy is very strong, over 2800 and 3173. The cross-off WNW wind keeps it clean. But this is heavy – over 7 feet – so experts only. That long period will mean long waits between sets, but when they come, look out.

Then from Thursday the 6th through to Monday the 10th of August, we get hammered by gale-force westerlies and stormy conditions. Swell goes huge – 13 to 16 feet from the southwest – but with near gale cross-shore winds and energy readings over 5000, it’s a total mess. That’s kite-surf country, not paddle surfing at Nanwan Beach.

Things clean up again around Tuesday the 11th of August. Tuesday afternoon brings a nice 7 foot southwest swell, light WNW cross-off breeze, and combined energy of 1017 – clean and solid. Wednesday the 12th is another good one: 6 foot southwest swell, glassy conditions, and a light cross-off. That afternoon is dead calm – a real treat for the second week. The water temp is about 85°F, which is normal for this time of year.

From Thursday the 13th onward, the swell drops to about 5 feet from the southwest, but the wind turns onshore from the northeast, making it just marginal.

Bottom line: the best waves are Monday afternoon the 3rd of August – glassy, clean, 3-foot east swell. For the experienced crew, Tuesday afternoon the 4th of August is a standout. In the second week, lock in Wednesday the 12th of August for a glassy, clean southwest swell session.

This is Rusty, out.
