The Lowdown

G'day, Rusty here. Look, I gotta be straight with you – this outlook for Little Avalon is a tough one to write. We're looking at a pretty barren run for the next sixteen days, so don't rush to grab your board just yet.

The water temp is sitting at 64°, which is pretty much what you'd expect for this time of year – nothing unusual there.

The pattern starts now and honestly, the whole first week is a write-off. From Thursday the 20th of August right through, we've got flat, weak, onshore slop. You're looking at tiny swell (1 ft to 4 ft) with a short period of just 6 to 7 seconds, so it's all windswell with no power. The combined swell energy barely nudges into three digits a few times [115], but it's paired with onshore or cross-onshore wind and the wave comment is "poor surf conditions" every single session. Nothing to see here.

This dead spell stretches all the way through to Tuesday the 25th of August. We finally get a tiny glimmer of hope on Wednesday the 26th of August morning, with the wind swinging offshore from the SW at 9 mph and the surf cleaning up. But the swell is only 2 ft at 8 seconds, and the combined energy is a weak [72]. The call is "surfable waves but very ordinary conditions" – so you could get a knee-high, clean little ripple, but it's not worth a drive.

Thursday the 27th of August morning keeps that offshore wind, but again we're stuck with 2 ft at 8 seconds and only [41] combined energy.

Now, the standout – and I'm being generous here – is the morning of Sunday the 30th of August. The swell bumps up to 5 ft at 8 seconds from the NE, and the combined energy jumps to a moderate [350]. The wind is offshore from the SSW at 16 mph, making it clean. This is the best on offer, but it's still only rated as "marginal surf forecast or questionable tide conditions". The period is short at 8 seconds, so it won't have much push or shape. It's a long way out and not certain, but if I had to pick a time to check the surf, that'd be it.

We then taper off into early September. Tuesday the 1st of September morning gives you glassy conditions with 3 ft at 8 seconds from the ENE. The combined energy is a weak [72] and it's "surfable waves but very ordinary conditions". Wednesday the 2nd of September morning is also glassy, but the swell drops to a tiny 2 ft.

Overall, this is a bleak run for Little Avalon. There are no solid groundswells in the mix, only inconsistent short-period windswell and mostly poor wind. The setup looks more interesting for kite surfing than paddle surfing on the bigger, windier days.

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.
