Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the next 16 days for Nanwan Beach (South Bay). Honestly, it’s a pretty bleak start. We’ve got a long stretch of nothing to get excited about.

For the first week, from the 28th of July right through to the 3rd of August, it’s a write-off. The swell is tiny, around 2ft to 3ft, with a weak 8-second period. The water is a warm 85°, which is pretty normal for this time of year. But the wind is mostly cross or cross-onshore, creating a chop that’s just not surfable. There’s very little energy in the water (around 122 or less). It’s poor, plain and simple. There’s a brief moment on the morning of the 1st of August where it goes glassy, but the swell is just 2ft and short period – not enough to do anything with.

We then hit a blank spot on the 3rd of August. The swell direction swings to the east, but the wind is onshore, and the energy is moderate (around 291). It’s still a no-go.

Now, here’s the standout. The real story starts on the 4th of August. Tuesday morning, we get a proper East groundswell with a very long period of 16 seconds, pushing 5ft. The wind goes light and cross-offshore from the west. The energy jumps through the roof to 1255. This is the best on offer. The waves will be clean, powerful, and well-shaped. The period is long, so expect longer lulls between sets, but the quality will be worth it. Tuesday afternoon gets even better, with 5ft swell and an energy reading of 1594. This is excellent surf for experienced surfers.

The 5th of August still has some size on Wednesday morning, with 6ft and a 18-second period, but it’s a bit more of a mixed bag as the afternoon drops off. From the 6th to the 9th, the swell gets too big for the break, pushing 11ft and over 8ft, which is strictly for experts. The wind stays clean and cross-offshore, but that size at this beach and reef setup will be a washing machine. It’s more of a spectacle than a paddle.

The second week from the 10th of August onwards, the swell drops back to 6ft to 8ft, but the wind turns messy and cross-shore. The energy is moderate to strong (around 730-1056), but the conditions are choppy. It’s a bit of a letdown after that solid 4th. The 12th of August offers a final glimpse of hope with cross-offshore winds and 7ft swell, but it’s nothing compared to that first Tuesday.

So, for the whole 16-day window, the clear winner is Tuesday the 4th of August. The 4th and 5th are your best shots, but the 4th is the real deal. Get on it.
