The Lowdown

Right, let’s have a look at what’s in store for the next couple of weeks at Little Avalon. I’ll level with you, mate – it’s a pretty bleak run for most of the forecast. We’ve got a solid 16-day window, but the first swell that’s worth paddling out for doesn’t show up until the 28th of August. That’s a good two weeks of mostly flat, tiny, or messy conditions to sit through.

From the 14th right through to the 27th, it’s a real struggle. We’ve got days of tiny 0.6ft to 1ft slop, with a lot of cross-onshore winds and choppy junk. The 16th does see a bump to 5ft, but it’s a short-period, wind-affected SE swell with a 6-second period, and the wind is straight cross-shore, making it a total write-off. The 17th through the 27th are all in the same boat – small, weak, and with poor conditions. Sunday the 18th morning offers a clean 3ft but with very ordinary conditions, so it’s barely surfable. The 19th morning is glassy at 3ft, but again, the wave quality is just average. This is a long, dry spell.

Now, the 28th of August is the one that has me talking. Finally, a proper pulse of energy. Friday morning sees a 5ft SE swell rolling in, with a decent 10-second period, and the combined energy is a solid 458 (moderate to strong). The wind is light offshore from the SW – a gentle offshore breeze, which will keep the reef at Little Avalon clean and groomed. That’s the standout. It’s a high-energy groundswell that suits this break, and the conditions are looking good. The water temp is sitting at 63°F which is about 2°F cooler than normal, so it’s a touch on the chilly side for the time of year, but nothing crazy.

The 28th afternoon holds similar size at 5ft, but the wind swings cross-offshore, and the forecast calls it marginal, so the morning session is the clear winner. The 29th drops back to 3ft with a 9-second period and cross-offshore winds, but it’s back to mediocre quality.

So, if you’re a patient surfer, hold out for the morning of Friday the 28th of August. That’s the only real highlight in a very quiet stretch. Before that, you’re staring at a lot of flat, onshore, or tiny junk. Stick with it, because the 28th looks like it’ll deliver.

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.
