The Lowdown
G'day, Rusty here. Let me level with you about Avalon-North for the next couple of weeks. It's a point break that’s usually pretty consistent and takes swell from the ENE, but honestly, the outlook is bleak for a solid stretch.
We kick off on Friday, 4th September, and there's basically nothing doing. Swell is tiny, around 1 ft from the NE with a short period of 8 seconds and weak combined energy (39). The morning is glassy, but the wave comment says it all: poor surf conditions. That theme runs right through the first week. Saturday and Sunday stay small with no real power, and the wind flips around, sometimes offering a clean look but not enough swell to bother with.
Monday the 7th is dead flat in the morning with just 0.7 ft (10 combined energy), glassy but useless. Tuesday the 8th brings a spike in swell to 7 ft from the SSE with a period of 8 seconds, and the combined energy jumps to 572—that’s moderate wave energy. But the wind is a cross-shore from the S at 12 mph, and the wave comment is "poor surf conditions." That size is getting into expert territory (over 8 ft would be too much), and the short period means it’ll be lumpy. The setup looks more interesting for kite surfing than paddle surfing on that day.
Wednesday the 9th has a brief window of clean surf with offshore wind from the WNW at 6 mph, but the swell is only 2 ft (58 combined energy). The afternoon turns ugly with a fresh cross-shore from the S at 19 mph and a choppy 6 ft. From there, we hit a long gap. From Thursday the 10th right through to the end of the forecast, every session is marked as poor surf conditions, with the combined energy rarely breaking 100. We get a couple of glassy or clean mornings (16th September morning has glassy conditions with 1 ft, and the afternoon is glassy with 3 ft from the ENE at 4 seconds period, 37 combined energy), but it’s too weak to recommend.
There is no standout period here. The only blip of note is Tuesday 8th September’s 7 ft swell, but the wind and short period ruin it. The rest is a long, flat run. For an area that’s usually consistent, this is a dud. Keep the board in the bag for a while.
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.
