The Lowdown
Alright, Rusty here, breakin' down the next couple of weeks at Vunaniu. This reef rarely pumps, but when it does, it’s a special place. The first real surf we see is this Sunday, the 19th. It’s just okay – a 4ft SSW swell at a long 16-second period, but the east-northeast wind is blowin' at 19 mph, which is a bit messy. The water is a normal 77°F for this time of year, so no wetsuit drama.
The real standout, the one I’m stoked about, is Monday morning, the 20th. The swell is comin' up to 6ft from the SSW, and the period is a massive 20 seconds – that’s some serious groundswell pulling in a ton of energy. The wind is a moderate cross-offshore, so the waves will be clean and powerful. This is the best session of the run, no doubt. It’s a long-period swell, so expect those long lines and a bit of a wait between sets, but the shape will be perfect for the reef.
Tuesday, the 21st, is still good. The swell drops a little to 5ft, still with a 16-second period, and the wind goes light, making it a clean, glassy morning. The energy is still strong. It’s a little smaller than Monday, but the wind is a lot friendlier.
After that, it gets tricky. Wednesday morning, the 22nd, has a moment of pure glass with a 4ft swell, but the wind is light onshore. It’s a short window of quality.
From Thursday, the 23rd, through the end of the week, the wind turns nasty – cross-shore and choppy. The surf is there, but it’s ugly. The swell drops to a dribble by the weekend of the 25th (around 3ft), with poor conditions.
There’s a strong pulse of swell again around Monday the 27th and Tuesday the 28th, with waves up to 7ft, but the wind is cross-shore or cross-onshore, which ruins the reef. The energy is high, but the quality is a big zero.
The very end of the window, on the 1st of August, shows a glassy morning with a small, weak 4ft swell from the east. It’s short period at 7 seconds, so it won’t have any punch, but at least the wind is off.
The only real standout in this whole two-week stretch is Monday the 20th. That’s the one to circle on the calendar. The rest is a mixed bag of wind and chop.
Rusty out.

A general guide to surfing at Vunaniu can be found by selecting the local surf guide option on the grey menu.

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.
