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.

Information about the Vunaniu Surf forecast

The above surf forecast table for Vunaniu provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Vunaniu can be found by selecting the local surf guide option on the grey menu. Our Vunaniu surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Vunaniu may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
