The Lowdown
G’day, Rusty here. Let’s cut to it: the surf at Little Avalon is looking pretty grim for the next sixteen days. We’re in for a long stretch of flatness, starting right now and running through the middle of next week. There’s a big gap with nothing worthwhile.
The only real bump in the road is Monday the 17th. The swell jumps to 3ft to 5ft, but it’s short-period junk at 6 seconds, and the wind is blowing 20 km/h from the ESE, making it a cross-onshore chop-fest. The combined energy is moderate at 165, but it’s not surfable. That one’s better for kites than boards.
Then, on Wednesday the 19th, we get a slight tease: a 5ft swell from the ESE, again with a short 7-second period. But the morning wind is dead glassy. That’s the highlight of the whole window – a clean, but weak, 5ft wave. It’s rideable, but it’s not going to be good.
After that, it’s all downhill. The rest of the second week is under 3ft, with light winds and clean conditions, but no energy. The period stays around 7 to 8 seconds, and you’ll be fighting for scraps.
So, honestly, your only real look is early on Wednesday the 19th. A glassy 5ft from the ESE. It’s not a standout, but it’s the best we’ve got. Otherwise, the water’s at 64°, which is about normal, and the surf is just... nothing. Keep the board in the car, but don’t expect much.
Rusty.

Information about the Little Avalon Surf forecast
The above surf forecast table for Little Avalon provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Little Avalon can be found by selecting the local surf guide option on the grey menu. Our Little Avalon 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 (Little Avalon) 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 Little Avalon 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.
