The Lowdown

Alright, let’s get into it. The next couple of weeks are looking pretty grim for Little Avalon. We’ve got a long stretch of small, weak, and messy surf ahead, with a few brief moments that might be worth a look if you’re desperate. The water’s sitting at about 64°, which is right around normal for this time of year, so at least the temp won’t put you off.

Right now, there’s nothing on offer. The first few days are all small, onshore junk with zero energy. Wednesday the 19th shows a little 4ft swell, but it’s coming from the ESE with a short 10-second period and the wind is straight onshore, making it a complete write-off. Thursday and Friday the 20th and 21st are even worse – tiny waves, weak windswell, and messy conditions. Saturday the 22nd has a clean morning with a light offshore SSW breeze, but the swell is only 1ft, so you’d be lucky to get a knee-high ripple. That’s basically a flat day.

We’ve got a real dry spell here. From the 19th right through to the 24th, there’s nothing worth paddling out for. The energy readings are all in the double digits, mostly under 100, which is weak and unimpressive. The swell direction is mostly from the east or northeast, and the wind is either onshore or cross-onshore, churning up the surface.

Then, on Tuesday the 25th, things finally look up – just a little. The morning brings a 5ft NE swell with a 7-second period, and the wind is glassy, dead calm. Combined energy jumps to 200, which is moderate. The wave comment says “expect good surf conditions,” but it’s still a short-period swell, so it’s not going to have much shape. It’s a small window, but if you’re keen, that Tuesday morning might be the best we get. The afternoon stays glassy with a 4ft ENE swell, so you could get a couple of hours in before it fades.

After that, it’s back to square one. Wednesday the 26th gets hammered by a strong breeze from the west, smashing the 3ft NE swell into a cross-offshore mess. The rest of the week into early September is a parade of tiny waves, onshore winds, and poor conditions. The energy readings drop back into the teens and twenties, which is barely surfable.

The only other blip on the radar is Thursday the 3rd of September. The morning shows a 7ft SE swell with an 11-second period, and the combined energy is a massive 1168 – that’s strong. But the wind is cross-onshore from the ENE, making it choppy and messy. The wave comment calls it “marginal” at best. That’s a big swell for an advanced reef break like Little Avalon, but the wind is going to ruin it. If you’re an expert and don’t mind a bit of chop, you might get some overhead waves, but it’s not going to be clean.

So, to sum it up: the standout is Tuesday the 25th, with glassy conditions and a small but surfable swell. The rest is a long, frustrating wait. If you’re desperate, the 3rd of September might offer some big, messy waves, but don’t expect much.

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.
