The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Honestly, I'm looking at this forecast and it's a bit of a tough one. We have a solid 16-day window ahead, but there's a real flat spell staring us in the face. The first real surfable energy doesn't show up until Tuesday the 8th, so we're looking at a gap of a few days with nothing to recommend.
The standout of the whole period, the only real window that gets the blood pumping, is that Tuesday the 8th. Little Avalon is the spot, and it's not messing around. We've got a solid 4 ft swell pushing in from the SE, with a period of 10 seconds. That's proper groundswell. The combined energy is a solid 'moderate' at 257. The morning session is looking the best with a clean cross-off wind from the South. It's an advanced, very consistent reef break, so this is for the crew who know what they're doing. With that swell size, it's going to be a proper challenge, not one for the beginners. The water temp is sitting at 65°, which is pretty much bang on average for this time of year, so nothing unusual there.
The Tuesday afternoon sees the wind swing a bit more cross-shore and the energy drops to 192, so still surfable, but the morning is the clear winner. After that, it's a long, slow decline back into tiny, weak waves or flatness. There's a little blip on the 15th with some 3 ft, short-period (7 seconds) windswell from the NE, but the energy is weak (54) and the onshore wind won't do it any favours. It's a no-go for me.
The rest of the forecast is a write-off – tiny waves, poor conditions, or flat spells. The last week of the forecast is particularly barren. So, if you're keen, pencil in the morning of Tuesday the 8th at Little Avalon. That's your window.
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.
