The Lowdown
Alright, mates, Rusty here. Let's talk about the next couple of weeks at Vunaniu. It's a bit of a mixed bag, so let's get into it.
We're looking at a reef break that's a bit of a tease – it's inconsistent, so you gotta pick your moments. The water's sitting at 78°, which is pretty much normal for this time of year, so not much to worry about there in a wetsuit.
The forecast kicks off with some decent swell, but the wind is gonna be a problem. Tuesday and Wednesday see a solid SSW groundswell in the 6ft to 8ft range, with a strong 16-second period carrying some serious energy (2573). But the wind is up and cross-shore, making things choppy. It's surfable for the more experienced, but it's not going to be pretty. The size alone on Wednesday morning at 8ft puts it in expert territory.
The chop cleans up a bit from Friday with the wind turning cross-off, but the swell starts to fade. We get a few days of smaller, but cleaner waves, in the 4ft to 6ft range. It stays clean through the weekend, but the energy drops right off and the period shortens up, so the quality just isn't there.
The start of the next week is pretty poor. Monday the 24th sees the swell swing around to the ESE with a short, weak 7-second period. It's a big letdown after the earlier pulse.
The real standout, the one you've been waiting for, is Thursday the 27th. The wind is forecast to be light and offshore, and we've got a clean 4ft SSW groundswell pushing in. Energy is weak-ish at 896, but the conditions will be glassy. It's shaping up to be the cleanest, most user-friendly surf of the whole period. It won't be big, but it'll be perfect.
Friday morning the 28th looks similar, with light offshore winds and 3ft of the same SSW swell, so that's another good window for a dawny before the seabreeze kicks in.
Further out, around Wednesday the 2nd of September, there's a promising sign with the wind going offshore again and a clean 6ft easterly swell showing up. It's a long way off, so I wouldn't book the trip around it, but it's definitely one to keep an eye on. There's some energy there at 587, but we'll have to see how it develops.
The rest of that second week is mostly small and onshore, not really worth getting excited about. Overall, the first few days have size for the experts if they can handle the chop, but the standout days are definitely the 27th and the morning of the 28th for clean, user-friendly waves.
Rusty.
