The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you: it's a grim run ahead. We're looking at a long, dry patch of tiny, weak swell and mostly average to poor conditions. Little Avalon is the only game in town, and even then, it's a struggle for anything worthwhile. The forecast shows a gap of several days at the start with no real surf to speak of, and honestly, it doesn't get much better.
The first real chance to get wet comes up on Thursday, 27 August in the morning. The swell is a pathetic 2ft from the NE, with a period of 8 seconds, giving us a combined energy of just 62. That's weak. The wind is a light S breeze, so it's cross-off and clean, but the waves are small and ordinary. The water temp is about average for this time of year, nothing to write home about. It's a paddle, but not a session.
Friday morning, 28 August, is the pick of a very poor bunch. The wind drops to a glassy 5 km/h from the W, and that's a major positive. The swell is still tiny at 2ft from the ENE with an 8-second period and combined energy of 45. It's not going to blow you away, but those glassy conditions will make the small waves look pretty. If you're dying for a surf, this is your window.
After that, it's a long, slow slide into nothing. The swell drops to 1ft and stays there for days. The wind shifts around, but it's all small, weak, and poor. We get a slight uptick in period on the 1st of September with an 11-second swell, but it's still only 1ft and the energy is 47. Not enough to get excited about.
The whole second week is a write-off. Swell heights drop to 1.0ft and 0.7ft, with combined energy values in the teens and twenties. You'll see some offshore winds on the 5th and 8th of September, but with waves that small, it's barely a ripple. There's absolutely nothing here that stands out. For a reef break like Little Avalon, you need a bit of size and direction, and neither is on offer.
So, the honest truth: the best on offer is the glassy, tiny surf on Friday morning, 28 August. It's not a standout by any stretch, but it's the cleanest and most surfable window we've got. The rest of the 16 days is a bust. Keep an eye on the charts, but don't hold your breath.
Rusty.

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.
