Updates in hr min s Forecast update imminent
Alright, gents, Rusty here. Let’s talk Avalon-South. The water temp is running a little warmer than normal for this time of year—nothing radical, but you’ll feel it’s a bit toastier than usual.
The bad news? We’re staring down a long, dry stretch. For the next two weeks, there’s barely a ripple worth paddling for. A few tiny bumps pop up, but they’re all below knee-high and mixed with sloppy cross-shore breezes or dead flat spells. The one sliver of hope is Friday, July 10th in the morning. Avalon-South will see a clean 5ft swell from the southeast (9-second period), with light WSW cross-offshore winds. Combined energy is moderate (471). It’s not massive, but for a beginner-friendly spot that’s fairly consistent, it’s your best bet. Crowds are often around, so don’t expect solitude.
After that, it’s a wipeout. Saturday, July 11th, has a clean 4ft swell but it’s dropping fast. From Sunday, July 12th, onward, wave heights fall below 2ft, and you’re looking at a long flat spell that lasts right through to Thursday, July 23rd. There’s a tiny twitch on Wednesday, July 22nd, with a 3ft north-easterly swell and clean offshore winds, but the energy is weak (66) and the period is short—nothing to get stoked about. Honestly, you’re better off leaving the board in the shed until something proper shows up.
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.
