The Lowdown
Alright, let’s break it down. We’ve got a slow start at Vunaniu, so don’t rush out.
Nothing worth paddling for the first few days – messy wind, bumpy water, barely a score. First real opportunity is Friday morning, August 28th. Wind drops to 5 km/h from the east, almost glassy, with a clean 4ft swell from the south‑southwest, period of 15 seconds. That’s groundswell, and it’ll have some push. The water’s 77°F, normal for this time of year. This reef can be inconsistent, and you might have company, but that morning sets up clean. The combined swell energy sits at 1024 – moderate, but enough for a fun session. The swell direction matches the spot’s sweet spot. That’s your best session of the first week.
Saturday the 29th steps back – smaller 5ft swell from the east‑southeast, but period drops to 9 seconds and the wind is cross‑shore. Only marginal.
The real standout is Wednesday morning, September 3rd – more than a week out, so treat it as a hopeful one. Swell jumps to 7ft from the south‑southwest, period 16 seconds, with a cross‑offshore breeze from the east at 20 km/h (12 mph). That’s solid groundswell, only for experienced surfers. Combined energy is strong at 2877. Inconsistent here, but the sets will be meaty.
After that, swell stays in the 5ft to 6ft range but wind gets stronger. Monday morning, September 7th offers 6ft from the SSW, 13-second period, clean cross-off wind – still decent but not as punchy as that 3rd.
There’s a dry spell of a few days before that Friday the 28th, and after the 3rd it stays rideable but nothing magic.
Keep your eyes on that Friday and that Wednesday. 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.
