The Lowdown

Right then, let’s have a look at what’s on the cards for the next couple of weeks at Little Avalon. To be honest, it’s a pretty slow start. The first week or so is looking very quiet and not really worth getting excited about.

We’ve got some small, weak pulses of swell, mostly in the 3ft range from the ESE, but the wind is all wrong. It’s coming from the ESE and ENE, giving us cross-onshore and cross conditions that just chop it up. The wave energy is low, with readings like 112 and 143 (moderate at best) on Monday and Tuesday, but the quality is just poor. You’d be wasting your time. The water temp is sitting at 63°F, which is pretty average for this time of year, nothing unusual there.

Wednesday the 19th morning brings a moment of hope. We get a glassy spell with a 2ft swell from the ESE, but the period stretches out to 10 seconds. The combined energy is moderate at 150, but the waves are described as “very ordinary.” It’s surfable, but only just. That glassy wind is a massive positive for clean conditions, but there just isn’t enough push to make it interesting. By the afternoon, the wind swings onshore and kills it.

The next few days are a write-off. We get a bit of a cross-offshore on Friday the 21st morning with a tiny 3ft swell and a combined energy of only 44 (weak), but the waves are still “very ordinary.” It’s clean, but barely rideable. Saturday and Sunday are even smaller, with glassy conditions on the 23rd but only 1ft of swell. That’s not surf.

The week of the 25th is a bit of a mixed bag. The swell stays small, but we start to see some clean conditions with cross-offshore and offshore winds on the 26th and 27th mornings. The waves are still described as “very ordinary” though, with heights of 2ft to 2ft and combined energy around 45-54 (weak). You might get a few knee-high chances, but don’t expect much.

Now, the standout window is the very end of the run, on Friday the 28th of August and Saturday the 29th of August. Friday sees a jump in size to 6ft from the NE, with a period of 8 seconds. The combined energy hits huge numbers – 770 and 792 (very strong energy). The wind is onshore and cross-onshore though, which makes it a bit of a mess for paddle surfing. That much energy with that wind could be more interesting for a kite session than a surf. It’s marginal for us.

Then Saturday the 29th of August morning is the real one to circle. The swell holds at a solid 5ft from the NE, with a 9-second period and a combined energy of 388 (strong). The wind goes glassy – dead calm. That is a proper window for clean, powerful waves. At 5ft, it’s getting into intermediate territory, but the glassy wind will make it super clean. The afternoon turns messy again, but that morning session is the best on offer across the whole 16 days, by a long way. It’s a shame it’s so far out – it’s a promising but not certain call.

Crowds at Little Avalon are often a thing, so get there early if you’re aiming for that Saturday morning.

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.
