The Lowdown
Alright folks, Rusty here. Let's have a look at what Vunaniu has in store for us over the next couple of weeks. It's a mixed bag, but there are a couple of windows that look worth getting keen on.
First up, the water temp is sitting at 77°, which is pretty much bang on average for this time of year, so nothing unusual there.
The forecast kicks off with a bit of a quiet start. Sunday afternoon is a write-off with a 19 mph cross-off wind mushing up a 7 ft swell – that’s a lot of energy (1118) but the period is short and the wind is messy for anything clean. The real story starts to build towards the middle of the week. There’s a period from the 12th to the 16th where the mornings keep offering clean, glassy or near-glassy conditions. On the 12th, Wednesday morning, we’ve got a clean 4 ft swell from the east with a 9-second period and only a gentle breeze. It’s not huge, but it’s clean. Then the 15th and 16th are both looking fantastic. Saturday the 15th, both morning and afternoon are glassy with a small but sweet 3 to 3 ft swell out of the SSW, carrying a very long 17-18 second period. That’s groundswell, and it’s going to wrap in nicely. The energy is moderate (597 and 578), so the waves will have some punch for their size.
But the absolute standout for the whole run is Monday the 17th. The morning session is the one to circle. We’re looking at a solid 6 ft swell from the SSW with a long 18-second period, pumping out strong energy (2182). The wind is a gentle 9 mph from the east, which is cross-offshore and will groom the waves beautifully. This is excellent, clean surf for experienced surfers. It might be a little too much for beginners at 6 ft, but for anyone with a bit of experience, that’s the call. The early part of that week from the 17th through the 21st holds some size, but the wind gets a bit more tricky.
Looking further out, there’s a promising morning on the 23rd (Sunday) with a 6 ft swell and clean NE winds at only 6 mph, but that’s a long way off, so keep an eye on it. The 24th drops right off.
So, to sum it up: the cleanest, best shaped waves on offer are the weekend of the 15th and 16th for small, glassy conditions, but the biggest standout is Monday morning the 17th of August for a solid, clean swell. Get in the water.
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. If you surf the same spot (Vunaniu) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
