The Lowdown
Alright mate, Rusty here with the imperial numbers.
Let’s be straight with you – this 16-day window for Little Avalon is a real mixed bag, and honestly, it’s a tough one to get excited about. The forecast is full of small, weak waves and average to poor conditions for most of the run. There are only a couple of moments that might get your heart pumping, but they’re buried in a lot of nothing.
The water temp is sitting at 63°F, which is pretty standard for this time of year, so no surprises there.
The very first chance for a surf comes in on Thursday morning, the 13th of August. We’ve got a tiny 2 ft swell from the ENE with a period of 10 seconds, and the combined energy is a weak 54. The wind is blowing 12 mph from the SW, which is offshore here, so the surf will be clean. It’s surfable, but it’s small and very ordinary. You’ll get a few if you’re desperate for a paddle.
After that, it’s a long, dry spell. From Thursday afternoon all the way through to Sunday the 16th, the conditions are just poor. The waves stay tiny, the wind is either cross-shore or cross-offshore, and it’s not worth your time. There’s a noticeable gap of several days with nothing on offer.
Then on Sunday afternoon, the 16th, things get a bit weird. The swell jumps to 5 ft, but it’s coming from the SE with a short period of 7 seconds. The combined energy hits 292, which is moderate, but that short period means it’ll be a messy, choppy affair. The wind is cross-shore, so it’s marginal at best. It’s not the kind of day you’d tell your mates about.
The whole of the following week, from Monday the 17th through to Saturday the 22nd, is a write-off. The wind is mostly onshore or cross-onshore, the swell is small and weak, and the energy barely tickles 100. It’s poor surf, plain and simple.
Now, the one standout in this whole outlook is Sunday afternoon, the 23rd of August. The forecast says we’ll see 4 ft of swell from the ENE, with a period of 9 seconds, giving a combined energy of 254. That’s moderate. But the real story is the wind: a cross-offshore breeze from the W at 9 mph. That’s going to keep it clean. The wave comment even says “expect good surf conditions,” which is the only time you’ll see that in this whole run. This is the best chance for a decent session, but it’s a long way out, so keep your fingers crossed.
The last day in the window, Monday the 24th of August, has a clean 3 ft swell with a 16 mph offshore wind in the morning, but the energy is still only 192. It’s surfable, but nothing special.
After that, it fades into tiny, weak waves right through to the end of the period on the 28th.
So, to be honest, if you’re a beginner, you’re not missing much. The 5 ft swell on the 22nd is too big for you anyway, and the rest is just too small. For the experienced crew, Sunday the 23rd afternoon is your best bet. It’s the only time the stars align for a decent wave. The rest of the time, it’s a waiting game.
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.
