The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Avalon-North.
Alright, let's get real. The next week and a half is a tough stretch for us at Avalon-North. We're looking at a solid run of weak, short-period windswell and onshore or cross-off winds that just aren't doing us any favours. From Friday the 24th of July right through to the end of the month, the energy is tiny and the conditions are messy. There's a big gap of poor to no surf until we hit the second week of August.
The first real glimmer of hope comes on the morning of Sunday the 2nd of August. We get a bit of a bump with a 3ft ENE swell, but the period is a short 6 seconds, so it's going to be fat and weak. The wind is a light offshore from the NW, so it'll be clean, but the wave quality is just "surfable but very ordinary." The combined energy is still moderate at 157, so it's better than nothing, but it's not worth getting excited about.
Things start to look a bit more promising on the morning of Monday the 3rd of August. The swell picks up to 5ft from the ENE with an 8-second period, and the wind is a light offshore from the SW. The energy is up to 254, which is solidly moderate. It's still a bit of a hop, skip, and a jump from being great, but it's the best we've seen in a while.
Now, the standout. If you're an experienced surfer and you've got Thursday the 6th of August marked on your calendar, you're in luck. The morning is looking absolute glass. The wind is dead calm, the swell is a solid 8ft from the SSE, and the period is a decent 8 seconds. The combined energy is a strong 826, and the forecast is saying "expect very good surf conditions." That's a big call. That 8ft is heading into the expert zone, but with glassy conditions, it's going to be a proper session for those who can handle it. The afternoon gets a bit choppy, but that morning window is the one.
Then, hold onto your boardies for the morning of Saturday the 8th of August. This is the big one. We're looking at a 13ft swell from the ENE with a very long period of 12 seconds. The combined energy is a massive 4699, which is just pumping. The wind is a light offshore from the NNW, keeping it clean. This is a major, powerful groundswell. For a point break, that long period is going to set up some beautiful, lined-up waves. It's for experts only at that size, but it's the kind of day you remember. It's a week and a half out, so it's a promising long-range call, but if it holds, it's going to be magic.
All in all, there's a lot of flat and poor in the first week. The real action is on the 6th and especially the 8th of August. The 6th offers glassy, powerful waves for the brave, and the 8th is a potential bomb for the experienced crew.
Rusty.

Information about the Avalon-North Surf forecast
The above surf forecast table for Avalon-North provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Avalon-North can be found by selecting the local surf guide option on the grey menu. Our Avalon-North 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-North) 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-North 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-North is 14 km (9 miles) from the city of 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.
