The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks. We've only got one spot in the mix, Vunaniu, so this is a focused call.
Right off the bat, the first few days are pretty grim. Sunday the 30th and Monday the 31st are a write-off with poor surf conditions and messy cross-shore breezes. It’s not worth paddling out for that. The start of the month isn't much kinder. Tuesday the 1st stays marginal, with a moderate cross-chop and a short-period 2.6ft swell from the SSW that just isn't going to line up. Wednesday the 2nd actually sees the swell size jump up to 5.9ft to 6.9ft, but the wind is still cross-shore and gusty, leaving the surface chopped up. The combined energy climbs into the strong range, but the quality just isn't there for a clean ride.
We finally get a glimmer of hope on Thursday the 3rd. The morning brings a clean window with a cross-offshore breeze from the east and a solid 6.9ft SSW groundswell (period 15 seconds). This is what we’ve been waiting for, but it’s still only rated marginal due to the size and strength. That said, Friday the 4th morning is where the standout sits for the first week. The wind eases to a gentle breeze, the direction goes cross-offshore, and we get a clean 5.6ft SSW swell with a 13-second period. For an intermediate crew, this is the pick of the early run. The water temp is sitting at a very pleasant 76.8°, which is bang on average for this time of year.
The weekend takes a step back. Saturday the 5th sees rain showers and building cross-shore winds, though the swell hangs in there at 3.3ft to 3.9ft. Not worth getting wet for. Sunday the 6th morning cleans up again briefly with a cross-offshore breeze and a 4.3ft, 16-second groundswell, but it’s another marginal call.
Now, for the second week, the outlook gets more interesting, but less certain. Monday the 7th morning looks promising, with a clean 6.2ft SSW groundswell (period 16 seconds) and a gentle cross-offshore breeze. The wave comment mentions it’s for experienced surfers – that size with that period will have plenty of push and will be too much for beginners. This is likely the best on offer for the whole period if it holds.
After that, the pattern gets messy again with stronger winds and lumpy conditions through the middle of the week. The swell energy stays moderate to strong, but the wind keeps it from coming together. A notable pulse shows up on Saturday the 12th with a big 6.6ft SSW groundswell, a very long 19-second period. The wind is cross-offshore, but that kind of period can make a reef break like Vunaniu (Fiji) unbelievably good if you’re in the right spot, or it might close out if the tide is wrong. Too big for beginners, and even for intermediates it would be a handful. That’s a promising but distant option.
Monday the 14th closes the period with another strong pulse: 6.9ft to 7.2ft SSW groundswell, 16- to 17-second period. But the wind goes back to a strong cross-shore, so it’s likely lumpy and only for the die-hards.
Overall, the standout window is Friday the 4th morning for a clean, manageable swell, and then Monday the 7th morning for a bigger, more powerful session. The distant pulses on the 12th and 14th are worth watching but are far out.

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.
