The Lowdown
Alright, Rusty here, switching to the old standard units. Let’s break down Little Avalon.
Straight up, this 16-day stretch ain't giving much love early on. There’s a big dry spell for the first several days where you’re better off finding a job. It’s a slow burn until the back half of the second week, when the ocean starts getting grumpy.
From Saturday 15 August to Tuesday 18 August, it’s mostly flat or tiny, with poor conditions. The swell energy is weak (17 to 139). No happy hour here.
Then on Wednesday 19 August morning, we get a moment of peace. The wind goes *glass* – zero to 5 km/h from the west. Swell is 1.2m (about 4 ft) from the ESE, with a moderate combined energy of (241). The water temp is about 63°F, about 2°F cooler than normal, so it’s not warm but it’s fine. This is a short window for the advanced crew on the reef. Not a lot of size, but pure, clean glass for those who can work it.
After that, another dead zone. From Thursday 20 August to Tuesday 25 August, the swell drops to under knee-high, and the energy barely registers. Winds are shifty – cross, onshore – but there’s no wave to ride anyway. A brutal week of waiting.
Now, hold on tight for the final blast. From Wednesday 26 August to Saturday 29 August, the power turns on. This is expert territory only.
On Wednesday the 26th, the swell pushes up to 2.4m (about 8 ft) with onshore winds and strong energy (707-801). It's messy and unknown, not the cleanest. By Thursday 27 August, it’s even bigger – 3.0m (10 ft) in the afternoon, with cross-onshore winds. The energy is huge (1009-1722). That’s a lot of water moving, but it’s choppy and gnarly.
The best of the best is Friday 28 August and Saturday 29 August. The winds switch to *cross-offshore* from the west and WNW at 20-25 km/h. Swell holds at 2.2m to 2.4m (7-8 ft) from the ENE and NE. The combined energy is strong (575-821). These are the standout days, even with a tide call being iffy. The wind cleans it up proper. For advanced surfers on a reef, this is the only time to really go for it in this whole run. For beginners, this is way too big – over 2.5m (8 ft) is expert only.
By Sunday 30 August, it backs down to about 0.8m (2-3 ft), and the afternoon goes glassy but weak.
So, if you’re patient, the payoff is Friday 28 August and Saturday 29 August. That’s the heavyweight session. The mid-week Wednesday 19th is the only clean small-wave option. Don’t bother with the rest.
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.
