The Lowdown
Alright, grab a coffee, let’s see what’s in store for Avalon-North.
Honestly, mate, it’s a pretty flat and frustrating run ahead. We’ve got a solid 16-day window to look at, but the first week or more is basically a write-off. Most of the time we’re looking at tiny, weak swell. The combined energy readings are pathetically low, often under 100 (like 32, 46, 23), which tells you there’s just no power in the water. You’d be bored out there.
We don’t really get a proper look until the morning of Monday the 7th of September. The swell finally bumps up a bit to 4ft from the NE, but it’s a short-period wind swell at 6 seconds, and the wind is a cross-onshore – it’s gonna be choppy. Not a day to get excited about.
By the afternoon of Monday the 7th, things get a bit more interesting, but for the right crew. The swell jumps to 6ft from the NE, and the combined energy hits 421 – that’s a solid moderate energy. The wind swings around to a cross-offshore from the NW, cleaning up the surface. But here’s the catch: at over 5ft and nearly 6ft, that’s getting into expert-only territory, especially for a point break. The period is still short at 7 seconds, so it’ll be a bit of a messy, fat wave. If you’re an experienced local who knows the rock, you might score a few, but it’s not a beginner-friendly session.
After that, it drops back down again. We see another little pulse on Tuesday 15th of September with a 5ft swell from the south, but that’s short-period junk from the S and it’s cross-shore, so it will be a lumpy mess. Then on Wednesday 16th of September, we get a 3ft SSE swell with a clean cross-off wind – the waves are surfable but very ordinary. The energy is only 131, so it’s weak.
The only true standout window, if you can call it that, is that Monday afternoon on the 7th. That 6ft NE swell with clean cross-off wind is the only time we get any size and clean conditions together, but it’s only for experts. The rest of the time, you’re looking at knee-to-waist high slop with poor conditions. The water temperature is about average for the time of year, but you won't be in it long enough to notice.
For the rest of us, it’s a long gap of nearly two weeks of nothing worth paddling out for. Keep the board in the car, but don’t wax it up just yet.

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.
