The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for Vunaniu. It's a reef setup, and it's inconsistent, so when it turns on it's special, but there's gonna be a lot of waiting around otherwise. This forecast is a bit of a mixed bag, and honestly, we're in for a dry spell before anything really gets going.
The water's sitting right around 77°, which is pretty much spot on for this time of year, nothing weird there.
We kick things off on Friday the 21st, but it's not pretty. We've got a 6ft south swell rolling in, but with a fresh 19 mph cross-shore breeze, it's all lumpy and chopped up. The combined energy is strong (1651), but the quality is just not there for a paddle. Honestly, with that much wind and a beach/reef setup, this might be more interesting for the kite crew than us.
That lumpy, poor quality holds through the weekend. Saturday the 22nd cleans up a little with a lighter cross-off breeze on a dropping 4ft south swell, but the scores are still marginal. Sunday and Monday look poor as well, with a shorter period swell that just isn't gonna hold its shape. We're looking at a few days of nothing worth changing plans for here.
We get a little flicker of hope on Thursday the 27th morning. The swell drops to 5ft from the SSW with a 15-second period, and the wind goes cross-off with a moderate breeze. The energy is still there (1527), and it's clean. It’s a marginal call, but that’s the best we’ve seen so far.
The real standout, and the one you want to circle on the calendar, is Monday the 31st of August. Early morning, it's dead clear, with a light 9 mph cross-off breeze from the ENE. The swell is a modest 3ft from the SSW, but it's a beautiful 12-second period. The combined energy is moderate (575), but the forecast is "expect very good surf conditions." For an inconsistent reef, that is a massive green light. That clean, glassy morning window will be worth the wait. There will likely be a crew there though, given it's "sometimes" crowded.
Beyond that, we get a few more marginal windows. Tuesday the 1st of September morning looks clean again with a 2ft, 16-second south swell, but it's small. Then on Thursday the 3rd afternoon, we see a jump in energy (1040) with a 3ft, 13-second SSW swell and a gentle cross-shore breeze, which gives it the highest score in the back half of the run. That's another one to keep an eye on.
After that, it starts building again. Friday the 4th and Saturday the 5th of September see the swell pump up to 8ft from the SSW, with a long 16-second period. The energy is massive (4094 on Saturday morning), but the wind is howling cross-shore at 15-19 mph. That's big, powerful, lumpy water – expert territory only, and even then, the wind is going to make it a serious grind.
So, to wrap it up: the first week is a write-off. Don't bother until the 27th at the earliest. The only true standout for clean, fun waves is the morning of Monday the 31st of August. The second week offers a few smaller, cleaner windows, but the end of the run brings a big, windy swell that's for the brave and the experienced.
Stay patient, keep an eye on that Monday.
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.
