Alright mate, let's have a look at what Avalon-South is doing over the next couple weeks. It's a pretty thin menu, honestly. We get a couple of wild days right off the bat, and then it just goes dead.
Tuesday, July 7th, is a big, heavy ocean. Swell is pumping in at 10 to 12 feet from the SSE. The power in the water is massive – talking energy readings of 2549 to 2766. But the 15 to 18 mph wind from the S and SSW is going to chop it up proper. This is a serious, powerful swell and with that wind, it's a full-on challenge for experts only. Beginners, don't even think about it.
Wednesday, July 8th, is still got some size, about 8 feet from the SE, and a moderate 1638 energy. But that cross-shore breeze is still mucking it up, making for a rough, bumpy surface.
We finally catch a break on Thursday, July 9th morning. The swell drops to a much friendlier 6 feet from the SE, with the energy easing to 804. The wind goes light and cross-offshore from the SSW. The water temp is about normal for this time of year. It's clean, it's rideable, and for a learner, this is your best bet of the whole forecast. The afternoon gets a bit onshore and messy.
Friday, July 10th morning, is another good slot. Similar 6-foot SE swell, but we finally get proper offshore wind from the WSW. It's light, around 6 mph, but that's plenty to keep the face clean. A nice window for a surf.
After that, the swell just falls out. Saturday, July 11th, has clean offshore breezes on a dropping 4 to 4-foot swell, but the energy is only at 270-289. It's small, clean, but nothing special.
Then we hit a dead zone. From Sunday, July 12th, all the way through to Tuesday, July 22nd, it's flat. Barely a ripple. A few tiny pulses of energy, but nothing that will break. It's a proper, solid run of flat weather. You'd be better off with a kite than a surfboard for nearly two weeks straight.
So, the short story: Tuesday and Wednesday are big and gnarly for pros only. The real standout, the cleanest and most fun wave of the whole outlook, is Thursday, July 9th morning and Friday, July 10th morning. After that, the swell is gone.
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.
