Nyang-Nyang Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a look at what’s coming up for Nyang-Nyang (Indonesia) over the next couple of weeks. I gotta be straight with you – the first week is a bit of a write-off. The surf is there, but it’s ugly. We’ve got a solid pulse of SSW swell, with wave heights hanging around 6 ft to 8 ft, and the combined energy is strong (values between 1784 and 3906). But the wind is a killer – a steady 12 mph from the SSE and SE, blowing cross-onshore, chopping everything up. It’s a real shame because the water is a warm 79°, which is about average for this time of year, but you won’t be enjoying it.

From Sunday the 6th through to Tuesday the 8th, the surf is rated as poor. The swell is a mix of SSW and SW, with periods around 14 to 18 seconds – that’s long-period groundswell, which usually means better shaped waves, but with this wind, it’s just a messy, bumpy ocean. Not worth paddling out for.

Wednesday the 9th through Friday the 11th sees the wind shift to a light onshore at times, with a gentle breeze on Wednesday from the S and SSE. The wave heights are still solid, around 8 ft to 8 ft, and the energy is strong (values up to 3182). The rating improves to “marginal,” but it’s still not good. The conditions are “unknown” or “fairly choppy,” so you’d be fighting for anything clean. This is a reef break, so those long-period swells (16 to 17 seconds) could be wrapping nicely, but the wind is just not cooperating.

Saturday the 12th to Sunday the 13th is more of the same – poor surf, cross-onshore winds, and wave heights dropping to 5 ft to 6 ft. The energy is still moderate (1404 to 3050), but it’s all messy. Monday the 14th to Wednesday the 16th is a mixed bag of poor and marginal, with the same cross-onshore story. The swell drops to 6 ft to 7 ft, and the periods shorten to 14 to 16 seconds. Honestly, there’s nothing here worth getting excited about.

Now, the best on offer is looking like Thursday the 18th and Friday the 19th of September. The swell builds to 7 ft to 10 ft from the SW and SSW, with periods of 16 to 17 seconds. The combined energy jumps to very strong values of 3299 and 4451. The wind is still cross-onshore from the SE and SSE, but at a gentler 9 mph on the 19th, which might just clean it up a bit. The rating is still only “marginal,” but this is the biggest swell of the period. The wave height over 8 ft on the 19th means this is for experts only. If you’re a confident surfer and you can handle the cross-onshore chop, this might be your window for some size. The long-period swell will favour the reef, offering better shaped waves, but expect longer lulls between sets. Crowds are possible at this spot.

Sunday the 20th and Monday the 21st keep the size up, with 7 ft to 10 ft from the SSW, but the energy is still strong (values up to 4268). The wind stays cross-onshore, and the rating is marginal. It’s a similar story – big, but messy.

So, the standout is the 18th and 19th of September for the biggest swell, but don’t expect perfection. The wind is the main issue throughout this whole forecast. For a reef break that loves a good SW swell, the wind is just not letting it shine. There’s a gap of poor conditions from the start until the 8th, and then a long stretch of marginal to poor surf until the 18th. If you’re a kite surfer, the cross-onshore wind and solid swell might be more interesting than paddling.

Rusty.
