The Lowdown
Alright, Rusty here. Let’s break down what’s on offer at Vunaniu for the next couple weeks. This reef break is a bit of a moody one – inconsistent – so when it lines up, you gotta be ready.
The first few days are pretty average. Sunday the 6th is a mess – cross-breeze and poor surf. Monday the 7th improves a bit with a cross-offshore wind and a 6ft SSW groundswell, but the energy is moderate and it’s still just fair.
The real standout is Tuesday morning, the 8th. That’s your best early call. Clean 6ft SSW swell, period stretching to 17 seconds – proper long-period groundswell. Combined energy is strong at 1613. With an offshore breeze, it’ll be glassy. This is the kind of session you remember. Just keep in mind, on a reef that long period can make waves stand up quick.
Wednesday the 9th and Thursday the 10th mornings are both glassy with 4ft SSW swell – small but clean. Perfect for a longboard or a fun fish.
Things start to get bigger from the 12th. Saturday the 12th has a 6ft SSW swell but with a 21-second period – deep ocean energy (3471). Cross-breeze, so it’s not perfect, but it’s got power.
Then Sunday the 13th hits hard – 12ft SSW, 18 seconds, energy at 6786. That’s expert-only. Cross-wind makes it messy.
Monday the 14th and Tuesday the 15th stay big – 8ft to 10ft – with cross-breezes and chop. Tough paddling, not for the faint of heart.
There’s a lull from Thursday the 17th through Friday the 18th with small weak surf – 2ft to 5ft and low energy. Not worth suiting up.
But Saturday the 19th looks promising again – clean 10ft SSW swell with cross-offshore breeze. That’s big and clean for experts. It’s a week and a half out, so take it as a hopeful look.
Bottom line: Tuesday morning the 8th is your best shot at clean, fun waves. Don’t sleep on it.

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.
