Vunaniu Surf Forecast and Surf Report

Alright, this is Rusty. Let’s get into it, mate.

We’ve only got one spot on the table for this entire 16-day stretch: Vunaniu. It’s a reef break that’s exposed to the south, needs a south swell, and it’s inconsistent, so when the waves show up, they’re not always a sure thing. Right now, there’s a bit of a slow start. The first real recommendation kicks off Friday morning, August 28. For the first few days, the energy is moderate but the wind is the real hero.

The standout window is Friday morning, August 28. A clean 4ft SSW groundswell with a long 15-second period, light east wind blowing cross-offshore at 6 mph, and glassy conditions. The combined energy is moderate (938). For Vunaniu, this is as good as it gets in this forecast – clean waves, good shape, not too big. It’s a reef break, so that long-period swell will wrap in nicely. It can get a crowd here sometimes, but on a Friday morning you might be in luck.

Saturday morning, August 29, also looks fun. The swell shifts to a short-period ESE at 5ft, with glassy winds from the WNW at only 3 mph. The wave energy is moderate (646). That short period (9 seconds) means it’ll be a little less powerful, but perfectly clean, so it’s still worth a look.

Sunday morning, August 30, drops to 3ft SSW swell with a nice 14-second period and glassy SSE winds at 3 mph. Clean, but small. Better for a longboard.

The water temperature is 77°F, with an anomaly of only 0.2°F, so it’s just about average for this time of year – no surprises there.

From Monday onward it gets a bit messy. The wind picks up out of the east-southeast, blowing cross-shore, and the swell stays around 3ft to 4ft but with moderate cross-chop. It’s not terrible, but it’s not the clean stuff we had over the weekend. By Wednesday, September 2nd, the swell bumps up to 7ft to 7ft from the SSW with a very long 16 to 17-second period, and the combined energy jumps to strong (over 2500). That’s a lot of power, but the wind is still cross-shore at 15 to 18 mph, so it’ll be lumpy and tough. That’s expert-only territory if you’re game, but the surface won’t do you any favours.

Thursday, September 3rd holds similar size (6ft to 7ft) but with similar cross-wind issues. It stays average.

Then we get a real highlight again on Friday morning, September 4th. A solid 6ft SSW groundswell with a 14-second period, clean east wind at 9 mph blowing cross-offshore. The combined energy is strong (1721), and conditions are clean. This is for experienced surfers – that size on a reef with that much energy needs respect, but the setup is good.

After that, the swell slowly fades through the second week, dropping back to 3ft to 4ft from the SSW with long periods. The wind stays mostly cross-off from the east, so conditions are clean but the size is small. It’s not a total write-off, but nothing will compare to the first Friday morning or the Friday on September 4th.

Overall, the best wave of the whole window is Friday morning, August 28 – clean, consistent groundswell, picture-perfect wind. The second best is Friday morning, September 4th – bigger but still clean. For the rest, it’s small and clean or bigger and choppy. Don’t sleep on that Friday morning session.
