The Lowdown
Alright mates, Rusty here. Let’s talk about Vunaniu. This reef break is inconsistent, so it’s not a place you can just rock up to any old time, but when it gets the right swell, it can be a gem. The water temp is sitting at 77°, which is bang on average for this time of year, so no surprises there.
The forecast starts off with a bit of a frustrating wait. The first few days are a write-off for decent, clean waves. The swell is there, but the wind is a problem. From Wednesday afternoon, the 2nd, through to the end of the next week, it’s mostly cross-shore breezes and a cross-chop on the surface. The wave energy is strong in the early days, with a combined energy of 2406, but it’s just not clean enough to get excited about.
The first real glimmer of hope comes on the morning of Monday the 7th. The swell is a solid 5 ft from the SSW, with a long 15-second period, and the wind turns cross-offshore, cleaning things up. The wave energy is still heavy at 1256, so there’s some grunt in the water. It’s a bit of a tricky call because the tide might be an issue, but it’s the best we’ve seen so far.
The standout moment arrives on the morning of Wednesday the 9th. This is the one. The wind goes completely glassy, a dead calm, with the swell hanging around 4 ft from the SSW, period of 15 seconds. Conditions are going to be silky smooth. The break is inconsistent, so you’ll be waiting for sets, but when they come, they’ll be clean and lined up. The wave energy is moderate at 800, but with the glassy surface, it’ll be a session to remember. Get on it.
After that, things get a bit messy again. The next week sees a big pulse of swell on the 13th, with a massive 13 ft SSW swell, but it’s accompanied by a 12 mph cross-shore wind. The energy is huge at 9229, but that’s serious, heavy water. Over 8 ft, this is for experts only, and the onshore wind is going to put a chop on it. Not the best combo. The 14th offers a slightly smaller 8 ft with cross-offshore winds in the morning, which is a better window for the experienced crew.
The long-range outlook into the second week is a bit of a mixed bag. The morning of the 17th shows a 3 ft SSW swell with a clean cross-offshore breeze, but it’s a bit marginal. The swell is small, but the wind is strong at 19 mph, so it might be a windswell session rather than the reef working its magic.
So, to sum it up: the window is tight. Wednesday the 9th morning is the absolute pick. If you miss that, Monday the 7th morning is your next best shot. The rest of the period is either too windy, too big, or just plain messy. This is a spot that needs patience, but when it pays off, it’s worth the wait.
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.
