The Lowdown
Alright, Rusty here again, now in feet and miles.
We’re looking at Vunaniu and the surf across the next 16 days. The water is sitting at 25° – that’s right on the money for this time of year. This first Saturday morning, July 25th, the swell is small at about 3 feet out of the SSW with a clean cross-off breeze and some decent energy in the water. The afternoon gets messy as the wind shifts. Sunday’s not much better – a bit bigger but choppy.
Monday and Tuesday see the swell pick up. Monday morning we’ve got about 8 feet from the SSW with a very long 16 second period. That’s a lot of power (combined energy over 2900), but the cross-breeze messes with the surface. By Monday afternoon, we’re looking at 8 feet – that’s expert territory and still not clean.
Wednesday July 29th morning looks cleaner with a 6 foot SSW swell and cross-off wind, but the period has dropped. The rest of that week and into early August is mostly small, under 3 feet, with clean enough conditions but not much grunt.
The best bet is Sunday morning, August 2nd: a clean 4 foot SSW groundswell at 14 seconds with a gentle cross-off. Glassy conditions make it even better. But the real standout is Monday morning, August 3rd. The wind goes completely glassy at about 3 mph from the SSW, with a clean 3 foot SSW swell at 13 seconds. That’s just beautiful – the reef will be friendly, the waves will have shape, and you’ll have the place looking its best. After that, the wind turns onshore and the swell gets overhead again (over 8 feet) but very choppy and bumpy right through the middle of the second week.
So, to sum it up: the early Saturday session is clean and small, but the absolute pearl is that glassy Monday morning, August 3rd. Vunaniu doesn’t always break, so these windows are worth clearing the diary for.
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.
