The Lowdown
Alright, let me lay out what’s ahead over the next couple weeks. We’re looking at a pretty quiet stretch, with just a few windows where you’d actually want to get wet.
Right now, and for most of the coming days, it’s pretty grim. We’ve got a run of poor surf conditions from Tuesday through early next week. Swell drops off fast, with combined energy around 356 (moderate) on Tuesday morning, then falls into the double and low triple digits—weak to moderate wave energy at best. Wind is mostly cross-onshore or onshore, and the period is short at 7–8 seconds, so the waves are crummy and lack any power. That’s a lot of days with not much to bother with.
Now, the first real highlight shows up on Wednesday, September 2nd. The morning at Little Avalon has a small bump: 2 feet from the east with a 10-second period. That’s a better shape than what we’ve had, and the wind is light offshore from the SSW, making it clean and glassy. Combined energy is 69 (weak), so it’s not punchy, but it’s clean and easy. For a wave that normally needs NE swell, this ENE direction is okay but not ideal. It’s surfable and clean, but don’t expect anything hollow.
Then things get interesting for Friday, September 4th. The afternoon brings a 5 feet swell from the NE, period dropping to 6 seconds (short period windswell), but the combined energy jumps to 229 (moderate). Wind is light SSE cross-offshore, so the face stays clean and smooth. Saturday morning follows with 3 feet at 8 seconds from the ENE, energy 130 (moderate), but the wind turns cross-on from the north, making it a little bumpy. Still, of all the days, Friday afternoon is the standout. That 5 feet with clean cross-off wind is the best quality you’ll get. It’s not groundswell, but for the size and clean conditions, that’s the one.
After that, it fades again. Sunday the 6th and Monday the 7th are poor—small, windy, not worth the effort. Into the second week, there’s a brief clean window on Tuesday morning, September 8th, with glassy conditions but only 1 feet at 8 seconds and energy of 41 (weak). It’s flat but pretty, maybe a longboard session if you’re bored.
Best on offer: Friday, September 4th afternoon at Little Avalon. That 5 feet NE swell with the 9 mph cross-off breeze from the SSE is your best chance at a fun wave. The water temperature is about average for this time of year, so standard spring suit stuff.
Stay tuned, forecasts can change, but for now, don’t get your hopes up.

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.
