Alright folks, Rusty here. Let's have a look at what's on the cards for Avalon-South.
Right off the bat, the next few days are looking pretty flat and ordinary. The water temperature is sitting at 67°, which is about a degree and a half warmer than usual for this time of year – a bit of a nice surprise if you're having a paddle, but there's hardly any surf to enjoy it with. We've got a long gap here; from Friday 3 July right the way through to Sunday 6 July, there’s nothing worth paddling out for. Small, weak swells with poor conditions just don't cut it.
Things change pretty dramatically come Monday morning 6 July though. A solid SSE swell pushes in, hitting 8ft with a moderate 10-second period. The energy jumps right up to a strong (1110). The problem? A cross-onshore wind is going to chop things up, so while the size is there, the quality isn't. The forecast keeps these lumpy, messy conditions going for days. By Tuesday morning 7 July, the swell holds at 8ft from the SSE, and the energy is very strong (2147), with the wind shifting to a clean cross-offshore, making for much better conditions. Still, this is big – over 8ft is expert territory only, so don't be fooled into thinking it's for everyone. The period at 10 seconds is a solid groundswell, and combined with the size, you'll be looking at proper lines. Crowds are likely here too, so be prepared to share.
The best of the whole run looks like it could be Friday morning 10 July. We've got a still-juicy 7ft SSE swell (10-second period) with strong energy (1001), and the wind is a light cross-offshore. That's a recipe for clean, well-shaped waves, and the drop in wind makes a huge difference. It’s still a big swell for a beginner though.
After that, the surf backs down. Saturday 11 July morning offers a more manageable 5ft from the SE (368 energy) with a light offshore wind that’ll clean it up – a much better call for the intermediate crew. By Saturday afternoon, it's down to 4ft and glassy, but the conditions are described as just ordinary.
From Sunday 12 July onwards, the swell fades fast, and we're back into small, weak waves, and eventually a complete flat spell from Tuesday 14 July through Wednesday 15 July. There’s a tiny blip on Thursday 16 July afternoon with 4ft from the SSE, but with a 22 mph wind, it's more of a kite-surfing proposition than a paddle session. To be honest, the whole run after the 11th is a write-off.
Stay patient, that Friday 10 July morning is the one to circle.
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.
