The Lowdown
Alright, this is Rusty.
Right off the bat, I gotta be straight with you – it’s looking pretty bleak for Little Avalon over the next couple of weeks. We’ve got a solid 16-day window here, and unfortunately, the first week and a half is a write-off. The swell is tiny, the winds are messy, and the surf just isn't showing up. Don’t bother checking it until we get to Thursday the 20th.
Let’s start with the real kicker. For the first seven days, from Thursday the 13th right through to Wednesday the 19th, it’s flat. We’re looking at waves barely pushing 1 ft to 1.0 ft. That’s ankle-snapper territory with a combined wave energy reading of only 17 to 35 (weak). The wind is a mix of cross and cross-onshore from the SE and ESE, which just throws a little chop on top of nothing. There’s nothing to even bother paddling for.
Now, come Thursday the 20th, there’s a tiny glimmer. We finally get a morning with glassy conditions – that’s a great sign – but the swell is still only 3 ft from the ESE at a short period of 7 seconds. The combined energy is 87 (still weak). It’s surfable, but it’s "very ordinary conditions". You might get a few bumpy ones, but I wouldn’t plan a trip around it.
We’ve got another little pulse on Saturday the 22nd. The morning sees a clean 4 ft swell from the NE with a moderate cross-offshore wind from the W. The energy picks up to 141 (moderate). By the afternoon, the wind goes fully offshore from the WSW at 12 mph, which will clean it right up. The swell stays at 4 ft from the NE with a period of 8 seconds. This is probably your best bet of the whole run, but it’s still only scoring a 1 out of 10 for quality. It’s "surfable but ordinary". The water temp is about 63°, which is 1° cooler than normal for this time of year, so not unusual; a spring suit is fine.
Sunday the 23rd offers a similar setup. Afternoon offshore winds from the SW at 12 mph over a 3 ft swell from the ENE at a 10-second period. The energy is 120 (moderate), and it’ll be clean with the moderate offshore wind. Again, it’s ordinary but ridable.
From Monday the 24th all the way through to Friday the 28th, it fades right back out. We’re back down to 1 ft to 2 ft swells with weak energy readings of 15 to 49. The wind is mostly clean but the swell is just too small to do anything.
Honestly, for Little Avalon, it’s a stretch. The setup on Saturday the 22nd and Sunday the 23rd afternoons is the best you’ll get, but even then, it’s just "very ordinary". For a break that needs a good swell direction from the NE to work, and is exposed to it, we just aren’t getting the energy. This kind of flat run is more normal for the area during this part of the year, so don’t let it get you down.
Keep an eye on it. Forecasts can change.

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.
