The Lowdown
Alright folks, Rusty here. Let’s have an honest look at what Avalon-South has cookin’ for us over the next couple of weeks.
Right off the bat, it is a very slow start. We are looking at a dry spell that lasts from now all the way through the morning of Sunday the 9th of August. That’s several days of flat, unridable conditions with hardly a bump worth paddling for. The occasional tiny bit of east swell shows up, but it’s just ankle-slop with very poor conditions. This ain’t a surf forecast – it’s a swimming report.
Things finally kick off on the Sunday morning the 9th. We get a pulse of ENE swell pushing in at 4ft with a 9-second period. The combined swell energy is moderate (211). Wind’s blowing cross-offshore from the NNW, which keeps the surface reasonably clean. It’s surfable, but nothing to write home about – just ordinary.
Now, here’s the standout of the whole run. Monday the 10th of August, early session. The swell jumps to 5ft from the ENE, still with a 9-second period. The energy kicks up to a solid moderate (370). Wind goes fresh offshore from the WNW at 22 mph, and that means clean, lined-up waves. At 5ft, it’s getting a bit punchy for beginners, but for anyone with a bit of experience, this is the best we’ll see. The water temp is about average for the time of year at 64°. The afternoon sees the swell drop back to 4ft, still offshore, but it fades fast.
After that high point, we slide back into small, weak surf for days. There’s another shot of energy on the 14th of August Friday afternoon, with a solid 8ft swell from the SSE, which is a big number, but the period is short at 9 seconds and it is onshore wind. That combo will be a messy, choppy mess – more of a washing machine than a wave. That size puts it solidly in the expert-only zone, and the conditions just aren’t there.
The weekend of the 15th and 16th of August offers a little hope. Saturday morning the 15th sees 5ft from the SSE with gentle offshore wind, which should give clean, rideable waves for competent surfers. Saturday afternoon holds 6ft with cross-offshore breeze and clean conditions. The combined energy is moderate-strong (416-474). It’s not perfect, but it’s the second-best window in the whole outlook.
The rest of the second week falls away into small, weak surf with poor conditions and onshore winds. There’s no real reason to get excited. The crowds at Avalon-South are often a factor, so if you do go out on that Monday the 10th or the Saturday the 15th, be ready for company.
Overall, the window is thin. Sunday the 9th is a warm-up, Monday the 10th morning is your best bet, and the Saturday the 15th is a worthy backup. The rest? Keep the board in the car and the wax in the wrapper.
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.
Avalon-South is 13 km (8 miles) from Dee Why. If you plan a holiday in Sydney North Coast, look for hotels and other accommodation in Dee Why. Dee Why has rooms for a wide range of budgets as well as car hire and transport links.
