The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what’s on the table for Vunaniu.
First thing’s first – don’t get your hopes up for the next few days. We’ve got a flat, bumpy start with tiny weak swell on Thursday the 13th. That’s not surf, that’s just a reason to stand on the beach and frown. The combined wave energy is only 303 – that’s weak, real weak. Winds are cross and messy, making it a total write-off.
Friday the 14th and Saturday the 15th see the swell lift a little to 2ft to 3ft, coming from the SSW and SW. The wind improves to cross-off, and the water is clean, but the energy is still nothing to write home about. It’s wave-able, but you’ll be scratching for a decent ride. The combined energy sits between 337 and 796 – still low to moderate. It’s marginal at best. Water temperature is 77°F, which is perfectly normal for this time of year – no surprises there.
Now, Sunday the 16th gives us consistent 3ft swell with clean cross-off winds and the energy gets up to 970 (moderate). Still, it’s nothing special. The real standout is Monday the 17th. That morning is where it’s at: a glassy 5ft SSW groundswell with a period of 16 seconds and a combined energy of 1276 – proper moderate and building. Winds are glass, absolutely glass. This is the cleanest, punchiest session in the whole forecast period. Monday morning is the best on offer. The 16-second period means longer lines, so points or reefs will handle it well. For the less experienced, 5ft is fine, but watch for the power on those sets.
After Monday, the swell builds more – by Tuesday the 18th it’s 6ft with 16-second period from the SSW and energy climbing over 2000. That’s strong, meaty swell. But here’s the catch: winds turn cross-shore and fresh, kicking up a chop. It’s still surfable for the experienced, but it’s not clean. From Wednesday the 19th through to Thursday the 20th, we get 6ft to 6ft, but the period drops a bit and winds are cross or cross-off with a fresh breeze. It’s lumpy.
From Friday the 21st onward, the swell backs off gradually. Friday’s 4ft to 5ft with clean cross-off winds and moderate energy (1140) is decent but nothing to rave about. Saturday the 22nd sees a drop to 3ft to 3ft with clean winds – sessionable but small.
Then from Sunday the 23rd through to the end of the period, it fades into tiny, weak, and inconsistent conditions. The energy drops below 300, swell height sits at 2ft to 3ft, and winds go glassy at times but the swell just isn’t there. By Wednesday the 26th, the period drops to 7 seconds – that’s short-period wind chop, barely surfable. It’s a long gap of poor to ordinary conditions from the 23rd to the 28th. The last few days of the forecast are just poor.
Bottom line: if you want the one true standout, get in the water early Monday morning, August 17th. That’s the call. After that, it’s a slide into mediocrity. The longer-range stuff around the 21st to 22nd is worth a look, but it’s not the same level. Crowds are possible at Vunaniu – it gets busy when the conditions are good, so Monday could have a few heads out.
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.

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.
