The Lowdown
Alright, let’s get real. The surf this week is not lighting the world on fire, that’s for sure. Friday the 7th is straight-up junk. We got a 12ft southeast swell, but it’s all over the place with a short period and a fresh cross-shore messing it up. The energy is strong (2020), but it’s a mess. Don’t bother.
Saturday and Sunday, the swell backs down to around 7-8ft, but that short period is still there. It’s cross-offshore and clean, but it’s weak and inconsistent. The energy is moderate, but the quality is poor. You’re just paddling around out there.
Monday the 10th, we finally get a glimpse of something good. Swell drops to 4ft, but the period jumps to 16 seconds. That’s proper groundswell. The wind is okay, and it’s clean. Energy is moderate (1363), but it’s small for this spot. Still, a step in the right direction.
Tuesday and Wednesday are just average. A few waves, but nothing to get amped about. The real change is Friday the 14th, where it stays clean with light winds, but nothing big.
Saturday the 15th, keep an eye on the afternoon. It gets glassy with a small 2ft southwest swell with a 18-second period. That’s a long one, but it might not have the size to hold up. A fun, clean session if you’re desperate.
But the big one is Sunday, August 16th. This is the day. The swell jumps to 8ft, but the period is a solid 16 seconds, and it’s coming from the southwest, which is exactly what this break wants. The wind is light, and the afternoon is glassy. The energy is huge – 3181 in the morning, 2863 in the afternoon. That’s powerful, strong surf. It’s for experienced surfers only at this size – anyone else is going to be in over their head. But for the crew, this is as good as it gets in this window. It’s about a week out, so it’s promising, but keep your fingers crossed.
After Sunday, it’s a downturn. Monday the 17th brings onshore winds and the quality tanks. The rest of that week is a mix of messy, choppy conditions and onshore breezes.
We get a little bit of life back on Thursday the 20th with a 8ft east-southeast swell, but it’s a short 7-second period, so it’s going to be crumbly and soft. And then the final Friday and Saturday just fall apart with lumpy, cross-shore chop.
So, the short story: there’s one standout window, and it’s Sunday, August 16th at Vunaniu. That’s your shot. Everything else is just waiting for something better.

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.
