The Lowdown
Alright, let’s get into it. The ocean’s got a pulse, but it’s a messy one for a while. We’re looking at a solid SSW groundswell pushing through, but the winds are going to be the main story early on. There’s some decent size on the way, but we have to pick our windows.
Right off the bat, Tuesday the 15th, we’ve got a serious 3.0m swell hitting Vunaniu (Fiji). The energy is huge – 4617 – but the wind is blowing 20-25 km/h from the east, cross-offshore. It’s clean, but it’s a raw, powerful ocean. This is not for the faint-hearted. The period is a long 17 seconds, so there’s plenty of push, but at that size, and with that energy, it’s challenging. We’re looking at more of a big-wave session than a fun one.
Wednesday the 16th sees the swell back off a touch to 1.7m, but the period is still a solid 15 seconds. The morning looks like the pick, with a light 15 km/h east cross-offshore breeze and clean conditions. The energy is still strong at 1419, but it’s a much more manageable size. For experienced surfers, this is the standout of this early stretch. Water temp is about average for this time of year, so a rashie or a springy will do.
Then we hit a bit of a lull. Thursday and Friday drop off in size, and the winds turn onshore. Friday morning the 18th is glassy and small, only 0.8m, but it’s the calm before the storm. The weekend is no good – Saturday and Sunday are small, windy, and messy. Not worth paddling out.
Monday the 20th and Tuesday the 21st bring the swell back up to the 2.5m range, but the winds are cross-shore and lumpy. There’s still a ton of energy – over 2000 – but it’s not clean. The period is around 15 seconds, but the chop makes it hard work. Not great.
Now, here's where we need to look ahead. The best window is shaping up for Wednesday the 23rd. It’s still big – 2.2m – but the period jumps to 17 seconds, which is proper groundswell. The morning has a light cross-offshore wind from the ESE. The energy is strong at 2917, but it’s cleaner than what we’ve had. This is a better bet, but the cross-shore wind will keep it from being perfect.
The end of the week goes downhill fast. Thursday the 24th and Friday the 25th are all onshore winds with fresh 35 km/h cross-shore breezes and bumpy, lumpy conditions. The swell is still there, but it's a washing machine. Kite surfers might have a field day, but for a paddle surfer, it’s a write-off.
The final stretch, from the 26th through the 30th, is a mixed bag. The swell stays solid, in the 1.5m to 2.0m range, but the period drops, especially around the 27th when it drops to 8 seconds – that’s short-period windswell, not the good stuff. The winds stay fresh and cross-shore. There’s still a pulse of long-period energy on the 29th, but it’s tangled up with the local chop.
So, all in all, we’ve got two real opportunities: the smaller, cleaner Wednesday morning on the 16th, and the bigger Wednesday on the 23rd. Both have decent period and okay winds, but neither is perfect. The good news is, we’ve got a lot of energy in the water, so it’s not going away. We just have to be patient and pick the right tide windows. It’s not a classic run, but there’s waves to be had if you’re keen.

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.
