The Lowdown
Alright, Rusty here, switching to feet and knots for the land of inches.
First off, the first few days are a total loss. Wednesday the 15th and Thursday the 16th are blown out with strong cross-shore winds and lumpy chop. The swell is there, but it’s not surfable. Don’t bother.
From Friday the 17th, the wind turns cross-offshore, and the combo energy is building, hitting moderate to strong levels. The issue is the swell is mixed: short-period ESE and a long-period 16-second groundswell from the SW. That long-period stuff is better for a reef, and Vunaniu is a reef. But the rain and fresh breeze kill the fun.
Saturday the 18th and Sunday the 19th are similar: clean-looking waves, but marginal surf. You’ll get some rides, but nothing to write home about.
Monday the 20th morning is the first real glimmer. The wind is a moderate breeze, and the swell is a super long 20-second groundswell from the SSW. Wave height is only 4ft, but with that period, it’ll have shape and power. The energy is strong. This is a solid option for experienced surfers.
The standout is Tuesday the 21st morning. The wind is light, glassy, and the swell is 5ft at 16 seconds from the SSW. The energy is strong (1670), and conditions are excellent for experienced surfers. This is the best day of the first week. The afternoon turns to junk, so get on it early.
After that, there’s a lull until Thursday the 23rd morning. The wind goes glassy, with a 10ft SSE swell at 9 seconds. That’s a lot of water, and it’s only for experts. The energy is strong (1430), and it’s glassy. If you’re a confident surfer, that morning is a goer.
The following week, from Friday the 24th to Monday the 27th, the swell stays solid, with heights around 8ft and periods from 10 to 12 seconds from the SE. The energy is strong (up to 1793). But the wind is mostly cross or cross-onshore, so quality is just marginal. The best of that bunch is Saturday the 25th morning with a light cross-shore breeze.
The real late-week highlight is Monday the 27th morning. The wind is dead calm, glassy, and the swell is 6ft from the SE at 12 seconds. The energy is very strong (2165), and conditions are excellent for experienced surfers. That’s a proper session.
Finally, Tuesday the 28th morning is another glassy, clean window with a 4ft SSW groundswell at 15 seconds. The energy is still strong (1194). It’s a great, mellow option.
So, the pick of the forecast: Tuesday the 21st morning for the clean, long-period groundswell, and Monday the 27th morning for the glassy, powerful SE swell. Both for experienced surfers. Water temp is about average for the time of year.
Rusty out.

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.
