The Lowdown
Alright, let’s get real about Little Avalon. This reef setup is a consistent, advanced-level wave that normally likes a NE swell, but we’re staring down a pretty grim 16-day window. There’s no standout session in the whole run, so I’m not going to lie to you – it’s a tough stretch. The first real chance to even get a board in the water with decent conditions looks to be on Wednesday morning, September 2nd.
We’re looking at a long stretch of really weak surf. The combined swell energy is mostly in the double digits, only occasionally nudging into the weak 40s or 60s (92 on the 30th of August, but that’s with a poor cross wind). The swell is tiny, barely breaking 2 ft with the few exceptions of a 3 ft to 4 ft spike, but that comes with onshore winds or short, weak periods. The water temp is about 64°, which is pretty normal for this time of year, so no surprises there.
The first few days are a write-off. Sunday the 30th of August has a tiny 2 ft SE swell and a cross breeze – not worth the paddle. Monday and Tuesday are flat with glassy or light wind, but the swell is only 1 ft. It’s a total dud.
Then we get to Wednesday, September 2nd. This is the best the whole forecast has to offer. The morning is clear with a light WNW cross-offshore breeze at 10 mph. The swell is a pathetic 1 ft from the ENE at 10 seconds, and the combined energy is only 48 – weak. The wave comment says “surfable waves but very ordinary conditions,” and I’d give it a 1 out of 10. It’s clean, but it’s a knee-high dribbler. The afternoon is even lighter with a cross-offshore breeze, but still just 1 ft. If you are desperate for a paddle, this is the only window. The long period (10-11 seconds) means the sets will be a bit more defined, but at this size, it’s barely a ripple.
After that, it’s a desert. Thursday and Friday are flat with glassy conditions, but the swell is 1 ft or less. The weekend of the 5th and 6th of September shows a slight bump to 3 ft-4 ft NE swell, but it’s short period (4-5 seconds) and accompanied by strong onshore winds or a fresh cross-offshore breeze that’s too strong for the tiny waves. The 7th and 8th are back to tiny, weak swell with onshore wind. The whole second week is a total wash – the combined energy rarely hits 40, and the swell stays under 2 ft, mostly with onshore winds. There’s a moment on the 11th of September with glassy conditions and a 2 ft ENE swell, but the period is only 8 seconds and the energy is 40 – still poor.
Honestly, for a break that is “very consistent,” this is a brutal run. The setup is more interesting for a kayak than a surfboard. Keep your board in the car, but don’t be surprised if you don’t get wet.

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.
