The Lowdown
Alright, this is Rusty checkin’ in. We’ve got a bit of a mixed bag on the horizon with only one real standout in the forecast period. Let’s get into it.
Alright, the first solid surf we see is on Sunday the 16th of August at Vunaniu. This is a reef break, and it’s an inconsistent setup here, so when it’s on, you gotta jump on it. Sunday morning is your golden window. We’re looking at a clean 3-foot swell pushing in from the SSW, with a very long period of 16 seconds. That’s pure groundswell energy. The wind is a light cross-off from the east at only 3 mph, keeping the surface glassy. The combined swell energy is a moderate 723, but the quality is top-notch. This break loves swell from the south, and that’s exactly what we’ve got. This is your best bet of the whole 16-day run. It could get a bit busy though, as crowds are sometimes an issue here.
For the rest of Sunday afternoon and into the week, things get messy. That long-period SSW swell lingers, but the wind swings onshore, picking up strong. Monday through Wednesday sees solid swell, with heights building to 8 feet on Wednesday morning with a combined energy of 2737. But with moderate to fresh cross-shore winds, it’s going to be choppy and poor. Not worth your time for a paddle.
By Thursday the 20th, the wind shifts to a cross-off again, cleaning things up, but the swell is becoming inconsistent with mixed periods. The swell drops to around 5 feet on Thursday morning, but by the afternoon the period crashes to 7 seconds, and energy drops to 979. It’s still clean, but the quality isn't there.
Friday the 21st looks alright, with a clean 6-foot swell from the SSE and a period of 13 seconds. The wind stays cross-off. The energy is moderate at 1919, but it’s a marginal call. The water temperature is about average for the time of year.
From Saturday the 22nd until the end of the month, it’s a real mixed run. Swell sizes fluctuate between 2 feet and 8 feet, with periods jumping all over the place from 6 seconds up to 17 seconds. The wind is consistently cross-off, so the surface will be clean, but the wave quality never gets that same Sunday morning magic again. The 6-foot SSW swell that rolls in on Friday the 28th and the 7-foot swell on Saturday the 29th have some power, with combined energies around 2073 and 1923, but the forecast is less certain that far out. The 8-foot swell on the 28th afternoon is getting big for beginners. The 5-foot to 6-foot clean surf from the SSW on the 27th and 30th could be a fun little window for the experienced crew.
In the second week, look for the morning sessions. The winds are best early. The best bet remains Sunday the 16th morning. Don’t sleep on that first window, because the rest of the run is a long trough of inconsistent, marginal surf.
That’s the word from the beach. Stay frothy.

Information about the Vunaniu Surf forecast

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.
