The Lowdown
Now, for those who think in feet and miles, here’s the same:
Alright, Rusty here. Let’s have a look at what’s coming our way for Little Avalon.
Honestly, mate, it’s a pretty grim stretch ahead. We’ve got a solid 16-day window, but for the first week and a half, the surf is just not there. There are long gaps where I wouldn’t bother paddling out. The first real sniff of something is on Friday the 11th, but it’s tiny—just 0.7 ft from the ENE with a very long 15 second period. The water temp is sitting at 64°, right about average for this time of year. The energy is weak (42), and while the morning has a light offshore, the swell is so small it’s barely a ripple. Not worth suiting up for.
Saturday the 12th is glassy calm in the morning, which is a tease, but the swell is still a pathetic 0.7 ft. Afternoon gets choppy with a cross-onshore. Sunday the 13th bumps up slightly to 4 ft from the NE, but the period is a pitiful 4 seconds—that’s windswell junk. The wind is onshore and strong at 16 mph, so it’s messy.
The next real standout? Not until Tuesday the 15th morning. We see 3 ft from the NE, with a 6-second period, and a clean offshore wind from the SSW at 9 mph. The energy is still low (64), and the wave comment says “surfable but very ordinary.” It’s about the best we’ve seen, but that’s not saying much.
After that, it’s back to tiny, crummy conditions until Monday the 21st, where we get 2 ft again from the NE with onshore winds. Nothing to write home about.
So here’s the best on offer: Tuesday, September 15th morning. Swell height is 3 ft from the NE, clean offshore wind, and the water is comfortable. It’s not big, not powerful, but if you’re desperate, that’s your window. The break is a reef, so with that northeasterly direction, it should line up alright, but the period is short, so don’t expect barrels.
If the swell doesn’t show, this run of flatness is a real bummer. But around here, it can change fast. Keep an eye on the forecasts.
Rusty.

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.
