The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a pretty grim start. We’ve got a real quiet spell coming up, so don’t bother paddling out for the first few days. The few waves that do show are small, weak, and mostly blown out by onshore winds. The water temp is about average for this time of year, nothing special there.
The first real chance to get wet looks like Thursday morning, the 27th of August. Little Avalon is a reef break, exposed to the swell, and it’s a very consistent spot. The swell is tiny, only 3 ft from the ENE, with a period of 8 seconds. The combined swell energy is low (76). But the wind is the big story here – it’s from the south at just 3 mph and glassy. That’s a major positive. It’ll be clean, but the waves are going to be small and weak. It’s a surfable option, but nothing to write home about. The crowds are often here, so expect company.
The outlook doesn’t really improve much after that. We’ve got a few more mornings with glassy conditions, like the 29th of August and the 31st of August, and early on the 2nd of September, but the swell just doesn’t get its act together. It hovers around 2 ft. The best-looking moment in the whole 16 days is actually Tuesday afternoon, the 1st of September. The swell jumps to 4 ft from the NE, with a 10-second period, and the combined energy hits 234 (moderate energy). The wind is a clean cross-offshore from the SE at 9 mph. That’s the standout. It’s still only marginal, but it’s the best of a bad lot.
After that, it’s back to small, choppy, or onshore junk. The session on the 4th of September has clean cross-offshore winds, but the swell is a pathetic 2 ft. Not worth the drive.
So, to sum it up: the first week is a write-off for anything fun. The only real window to get a few grovelly ones is that Thursday morning the 27th if you’re desperate, or keep your fingers crossed for the 1st of September. This is a tough stretch. It’s a very consistent break, so it won’t be like this forever, but right now, it’s a waiting game.
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.
