Nanwan Beach (South Bay) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into the outlook for the next couple of weeks.

We’re looking at a pretty quiet start for the area, with no real surf to speak of until the middle of next week. The first few days are a write-off with poor to marginal conditions, a mix of bumpy cross-shore winds and moderate energy that just isn’t coming together. The wait pays off, though, because we’ve got a solid window shaping up.

The pick of the outlook lands on Wednesday, September 2nd at Nanwan Beach (South Bay). The water is sitting at a warm 84°, which is pretty much bang on average for this time of year. The swell is a consistent 7 ft from the SW with a period of 9-10 seconds, pushing a moderate wave energy of 763-813. The big win here is the offshore wind from the NW, blowing at 12 mph, keeping the surface glassy and clean. This is the kind of day where you paddle out and feel the energy – it’s not a monster, but it’s clean and well-shaped. Crowds are often a factor here, so don’t expect a solo session.

The run continues into Thursday, September 10th as another standout. The swell bumps up to 10 ft from the SW, but with a short period of 8 seconds, so it’s a bit of a lumpy, powerful beast. Wave energy is strong at 1125-938. The wind is light from the NW and WNW, dropping to near glassy conditions in the afternoon. This is definitely for experienced surfers only – over 8 ft and short period means it’s heavy, fast, and won’t forgive mistakes. The combination of clean, light winds and solid energy makes it a real session to mark on the calendar.

What’s in between? After the 2nd, the surf drops off quickly. The 4th and 5th see small, ordinary 4 ft-4 ft SW swell with glassy or light offshore winds, but the energy is weak (224-259 – low-end). It’s surfable, but nothing to get excited about. The 6th fades further, and a rough patch from the 7th through the 9th brings messy, strong winds and a massive 12 ft swell on the 8th that’s too big for this break – wind and tide are favorable, but it’s a close-out situation. The 12th offers a clean 4 ft SSW swell with gentle offshore wind, but the energy is moderate (483), and the wind picks up to a fresh breeze later.

Overall, the two real standouts are September 2nd and September 10th. The first week is a slog, but the second week delivers power and clean conditions. Long-range call on the 10th is less certain, but the signs are promising.
