The Lowdown
Alright, Rusty here again, this time in feet and Fahrenheit.
We’ve got a dry spell on our hands at Avalon-South. From this Friday the 7th until Wednesday the 19th of August, the swell is barely a whisper—mostly under 2ft. The ocean energy is weak, reading between 10 and 80 (combined swell energy). Nothing to get excited about. Water temp is around 64°, which is pretty average for the time of year. If you’re into kiting, the wind picks up a few times, but for surfing, it’s a no-go.
The light at the end of the tunnel is Friday the 21st of August. We’ve got a serious set-up: a 7ft groundswell from the ENE with a long 13-second period, pumping energy up to 1398 (strong). Morning winds are light and offshore, making it clean. That’s expert-level surf—anything over 8ft is for the bold. That long period works best at a point or reef, so expect good shape. That Friday morning (21st) is your one true standout.
Saturday the 22nd still has 6ft from the ENE, period at 13 seconds, energy 1009 (strong). Morning is clean, but afternoon gets a cross-on wind. Crowds are common here, so be ready for company.
A long wait for a big finish. Mark that Friday the 21st on the calendar.
Rusty.

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