The Lowdown

Alright, let me tell you what I'm seeing for Little Avalon. It’s a reef setup over here, and honestly, for a spot that’s usually consistent, this 16-day stretch is looking pretty grim. The first real chance of catching anything worth paddling out for doesn't come until Saturday the 15th, and even then, it's a struggle.

The water temp is right around 64°F at the start, which is just about average for this time of year, so you won't need the thickest suit.

For the first week, it’s pretty much a write-off. A solid gap of nothing recommended from now until the morning of Tuesday the 15th. On that Tuesday morning, we get a little pulse of 3ft from the NE, with a short 7-second period. The wind is clean, coming cross-offshore from the south, which will keep the surface nice. The combined energy is weak at 73, so it's not doing much. It’s surfable, but it’s very ordinary. That afternoon drops off, and then the rest of the week is flat. There’s a tiny spike on the morning of Friday the 18th with some southeast swell hitting 4ft, but the wind is blowing onshore from the NE, so it'll be chopped and messy. Not worth it.

We finally get a glimmer of hope on Saturday the 19th. There’s a cleaner, longer-period groundswell pushing in from the ESE at 3ft, and a solid 11-second interval. The energy bumps up to 198 (moderate wave energy). The morning glass-off with a light offshore from the WNW means it could clean up and offer a few decent runners. Keep in mind, this is an advanced reef break, so the longer period will make the waves wall up nicely here. The crowd factor is listed as "often," so you won't be alone. The swell direction is just a bit off the optimal NE direction, but it’s still worth looking at.

After that, there’s another big gap of nothing much until the morning of Friday the 25th. That morning shows a 4ft swell from the NE but with a short 6-second period. The energy is moderate at 181, but the wind is only a slight air, so it could be glassy. The swell direction finally matches the optimum direction, but the short period will make it fat and weak. Still, it’s the kind of day you might find a sneaky one if you’re patient.

The Saturday morning of the 26th looks interesting with glassy conditions and a 3ft NE swell. The period is a bit better at 7 seconds, but the energy is still low at 99. It’s surfable but very ordinary again.

Honestly, if you're a regular looking for a proper session, the standout window is the morning of Saturday the 19th of September. The groundswell, clean wind, and the reef setup should produce the best waves on offer across the whole outlook, even if they’re not big. The second-best chance is the morning of Friday the 25th, but that's a longer-range call and less certain.

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.
