The Lowdown
Alright, grab a seat, let's talk about the only spot in the window that's got any real potential: Little Avalon. This is a heavy, advanced reef break that's very consistent, so it's usually firing or at least doing something. It's a tough wave, not for the faint-hearted, and it's often crowded, so you'll be fighting for a share.
Right now, it's a bit of a slow start. For the first few days, we're looking at tiny, weak waves with poor conditions. The combined energy is barely a whisper (39), and it's just not worth paddling out for. You'll be waiting through a lot of empty lulls. This flat spell hangs around for a good chunk of the first week, with hardly any surf on offer.
The first real hint of life comes on Wednesday, the 9th of September. The morning session sees a small bump of 2ft swell from the SE, with a period of 7 seconds. The combined energy is still a modest 58, but the wind is light and clean, which is a massive positive. It's surfable, but very ordinary. The afternoon dies off again.
The reliable action doesn't really kick in until the second week. On Monday, the 14th of September, we get a solid jump. The morning sees a 4ft swell from the NE, with a period of 7 seconds. The combined energy pushes into the moderate range at 183. The wind is cross-onshore and choppy, so it's not going to be picture-perfect, but there's real push in the water. This is a solid, powerful wave for the experts who know how to handle it.
The best window for clean conditions looks like Wednesday, the 16th of September. The afternoon is dead flat calm, with glassy conditions and a 3ft swell from the ENE. The combined energy is low at 23, but with zero wind, the surface will be like a mirror. It's a small, clean day for those who can make the most of a little bit of swell.
Looking further out, the very end of the period gets messy. Strong winds blow through from the 17th to the 19th, making it a complete write-off. The water temp is about what you'd expect for this time of year, so no surprises there.
The standout? It's got to be that Monday the 14th morning. The swell is the biggest in the whole run, and while the wind isn't ideal, the energy is there. It's a true expert's window. The Wednesday the 16th afternoon is a close second if you're after a glassy, smaller wave session.
This is one of those spots where you have to be patient. The good news is, it's consistent, so there's always something around the corner. Forecasts can change, so keep your eyes peeled.

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.
