The Lowdown
G’day, Rusty here, lookin’ at the charts for Little Avalon. Truth be told, it’s a pretty grim stretch ahead. For a spot that’s a consistent, advanced reef break, we’re gonna be starvin’ for a wave for the better part of a fortnight. The first solid recommendation doesn’t kick in until late in the game, so be prepared for a long, flat spell.
Right now, we’re in a period of next-to-nothing. From Wednesday 2nd September through to Wednesday 16th September, the swell is tiny—mostly around 1.0ft to 3ft, with short, weak periods (5 to 10 seconds). The combined wave energy is pitiful, often in the single digits or low double digits (e.g., 54, 44, 27). The wind is a mixed bag—some glassy mornings, some cross-off breezes—but there’s simply no swell to work with. The water’s sitting at 64°, which is bang on average for this time of year, so no thermals needed.
There’s a small spike of energy on Thursday 10th September morning, with a 2ft, 8-second swell and a clean cross-off breeze, but it’s still only “surfable” at best—nothin’ to get excited about.
The only real standout in this whole 16-day window is Friday 11th September morning. The swell jumps to 6ft from the ESE, with an 8-second period. The combined energy is a solid 434, which is a strong, punchy amount of juice. This is a late-arriving, short-period groundswell that’ll be a handful. For a reef break, that short period might keep things a bit crumbly, and with the wind blowing straight onshore from the NNE, it’s gonna be messy. This is strictly for the advanced crew—beginners, stay well away, as it’s over the 5ft mark and will be a washout. The crowds are often here, so expect a few locals out.
That Friday afternoon, the swell drops to 5ft but the onshore wind picks up, making it even worse.
After that, the surf fades away again through the rest of the second week, with small, weak swells and mostly poor conditions. The morning of Monday 14th September has a 5ft ENE swell with a 7-second period and onshore wind—again, only for the desperate.
Bottom line: If you’re keen, the Friday 11th September morning window is the only time you’ll get a real wave, but it’ll be a battle. For the rest of it, you’re better off checkin’ the kite forecast. The long gap of near-flatness through the first week and a half is pretty normal for this area when the swell windows are shut.

Information about the Little Avalon Surf forecast
The above surf forecast table for Little Avalon provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Little Avalon can be found by selecting the local surf guide option on the grey menu. Our Little Avalon 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 (Little Avalon) 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 Little Avalon 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.
Little Avalon 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.
