The Lowdown
Alright, Rusty here again. Let’s talk Avalon-South in feet and degrees.
It’s a long, quiet start. From July 28th right through the end of the month and into the first few days of August, there’s nothing worth paddling out for. The water’s about 65°F, pretty normal for the season, but with no swell, that doesn’t matter.
The first real hope hits on the morning of Saturday, August 1st. A 5ft swell from the SSE with a 10-second period, and the wind is glassy. That’s a perfect clean sheet. The combined wave energy comes in at a moderate 549, so there’s some grunt in it. This is the clear standout session. Crowds are likely here, but for a beginner-friendly break, that morning glass is a blessing.
That swell sticks around for Sunday morning the 2nd, dropping to 4ft from the same direction, still with a 10-second period and a cross-off NW breeze keeping it tidy. Energy is still moderate at 341. Another solid window.
Then it all fades fast. Monday the 3rd is down to 2ft, and by the 4th it’s near flat. The second week shows some size – Thursday afternoon the 6th brings a 7ft SSE swell, but it’s under a moderate cross-shore with a cross-chop, so it’ll be a messy one. Honestly, that’s more kite-surfing conditions than anything. Friday the 6th and Saturday the 7th push up to 6ft and 7ft from the SSE, but with strong onshore winds at 15-16 mph, it’s a blown-out, choppy mess. That 7ft on Friday afternoon is way too big for beginners, and with the onshore wind, it’s only for the brave or the stupid.
Bottom line: the one true standout is that Saturday morning glass-off. The rest of the 16 days is mostly flat or blown out.
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.
