Alright, let’s switch to feet and miles for my American mates.
Right, mate, Rusty here. Let’s have a look at what the next couple of weeks are serving up.
Overall, we've got a solid run of swell kicking things off, but it’s not all smooth sailing. The first few days bring some serious size, then we hit a flat spell, before another pulse shows up in the second week with a bit more promise.
The action starts Monday, the 6th of July, but it's rough. We’ve got a powerful 10-foot SSE swell, but a stiff 15 mph cross wind is making a mess of it at Avalon-South. Add in a bit of light rain, and it’s a write-off. Tuesday the 7th isn't much better. The swell holds at 10 to 11 feet, and that's plain too big for a beginner spot like this. The wind swings cross-off at times, but it’s a day for the pros only, if anyone.
Wednesday, the 8th of July, is where we get a bit of a window. The swell drops to 8 feet from the SE, still solid, but the wind turns light cross-off in the morning. The water temp is about average for this time of year. It’s still heavy, but for experienced surfers, this is the pick of the first week. The waves will have some serious punch with that 11-second period.
After that, it fades fast. Thursday the 9th has some clean 7-foot surf in the morning, but that’s as good as it gets. By Friday, it’s down to 6 feet and the wind is getting flukey. From Sunday the 12th, it drops off a cliff – we’re looking at tiny 2-foot waves. Then Monday the 13th it’s flat. There’s a solid 5-day gap with nothing worth paddling for.
Then comes a glimmer of hope about a week later. Saturday the 18th, we get a fresh SE groundswell at 7 feet, with a long 11-second period and a clean offshore wind from the West. This is the one to circle on the calendar. The crowds could be a factor here, as it’s a fairly consistent spot.
For the rest of the second week, it’s back to small stuff and barely a ripple after that.

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.
