Righto, let’s have a look at what’s cookin’. I’m Rusty, and I’m gonna talk you through the next few weeks here.
We’ve got a bit of a mixed bag ahead. The first few days are actually looking alright, with some fun, clean waves to start, but then it goes pretty quiet for a long stretch. The real standout is Thursday morning, July 9, at Avalon-South. We’ve got a solid 5.9 ft swell coming from the SE with a 10-second period, and the combined energy is pumping at 826 – that’s proper moderate wave energy. The wind is light and cross-off, so the surf will be clean. The water temp is about average for this time of year, nothing wild there. This is the best on offer, no question.
Thursday afternoon, the swell drops off a bit in energy (641) and the wind goes cross, so it’s not as good. Friday, July 10, is still decent – morning has 5.9 ft SE swell with a clean cross-off breeze, and the afternoon goes glassy with 5.6 ft, energy at 580. That afternoon glass-off is a real treat. Saturday, July 11, sees the swell drop to 3.0 ft from the ESE, but the period stretches to 12 seconds, so it’s a nice long-period groundswell. Energy is down to 404, but the morning is clean with a cross-off wind. This is a good day for beginners.
From Sunday, July 12, the swell really starts to fade. Sunday morning has 2.0 ft with a strong offshore wind, but the energy is only 90 – weak. It’s surfable but ordinary. Then from Sunday afternoon right through to Wednesday, July 22, it’s mostly flat or tiny waves under 1.6 ft, with very low energy. There’s a big gap there of about 10 days with no real surf to recommend. The wind gets nasty toward the end of the second week, with strong cross-shore winds and some rain, so even when an 8.2 ft swell shows up on Thursday, July 16, the wind is a mess and the quality is poor.
So, to wrap it up: get out Thursday, July 9, and Friday, July 10, while it’s clean and fun. After that, it’s a long dry spell. Don’t hold your breath.

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.
