The Lowdown
G’day, I’m Rusty. Let’s chew the fat on what’s coming for Avalon-North over the next couple of weeks.
Honestly, it’s a tough stretch. We’ve got a 16-day outlook, but the first surf that’s even worth a look doesn’t roll in until Wednesday morning, August 26th. Before that, from Sunday the 23rd through Tuesday the 25th, it’s all small, messy, and poor. A real dry spell, so leave the board in the car.
Wednesday morning, the 26th, is the first real chance. The swell is a tiny 4ft from the NE, with a period of 8 seconds, so it’s short-period windswell. The combined energy is moderate at 140. The wind is light and cross-offshore from the SW, leaving the waves clean. It’s surfable, but ordinary. This break is for advanced surfers only, and with the swell this small, it’s not going to offer much punch. It’s a consistent spot, so you’ll get waves, but don’t expect any standouts.
Thursday morning the 27th is a touch better for conditions. The swell drops to 3ft from the ENE, still 8 seconds, but the wind goes glassy from the ESE. The combined energy drops to 78, so it’s weak. The water temperature is about average for the time of year, nothing crazy. The surf is clean but small – perfect for a beginner’s longboard if you’re patient.
Friday morning the 28th is the best of a pretty average bunch. The swell is 3ft from the ENE, 8 seconds, with a light offshore wind from the WSW. The combined energy is 86, still weak. It’s clean, it’s glassy, and it’s the closest we get to a decent window. This is the one to aim for. The break is a point, so it’ll handle the small swell okay, but don’t expect hollow waves. The swell direction matches the optimum ENE direction, which is a plus. Crowds are ‘often’ here, so expect company in the lineup.
After that, it fades fast. Saturday the 29th through the rest of the period is a mix of small, weak swell and onshore winds. The swell stays below 2ft, periods are short, and the combined energy barely cracks 50 most days. There’s a brief flash on Tuesday afternoon, September 1st, with a 2ft swell from the E, 11 seconds, and a moderate offshore wind from the W. The combined energy is 68, and it’s clean. But it’s so small it’s barely rideable. The 11-second period is a bit longer, which would usually mean better shape, but at 2ft, it’s just not enough.
The very end of the outlook, around Sunday the 6th and Monday the 7th of September, shows a little bump. Sunday afternoon has 2ft from the NE, 5 seconds, with a moderate offshore wind from the WNW. The combined energy is 41. Monday morning has 3ft from the NE, 6 seconds, with glassy winds from the SSE and energy at 62. It’s still small, but the glassy conditions are a nice touch. These are too far out to be certain, but they’re promising.
Overall, there’s no standout here. The only real highlight is Friday morning, August 28th. It’s not pumping, but it’s the cleanest, most consistent day in the window. If you’re an advanced surfer, you’ll get a few fun ones. For everyone else, it’s a wait-and-see game. The second week is a write-off for anything meaningful.
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.
