The Lowdown
Alright, let me tell you what’s happening at Little Avalon. It’s a reef setup, so it needs the right direction and size to fire. We’re looking at a pretty quiet stretch ahead. The water temp is about average for the time of year, nothing wild.
Right now, Tuesday the 15th, it’s small. We’ve got a 3ft NE swell with a short 7-second period. The combined energy is weak, only 69. Morning has a light offshore wind from the SW, so it’s clean, but the waves are tiny. By afternoon, the wind swings SSE and picks up, making it messy. Nothing to get excited about.
Wednesday the 16th and Thursday the 17th are basically flat. Swell drops to less than 1ft. There’s a long-period 13-second pulse on Thursday morning, but it’s so small it barely registers. The whole week from Wednesday the 16th through to Monday the 21st is a long, boring gap with almost no surfable waves. You’ll see a couple of days with a faint 1ft bump, but it’s not worth paddling out for.
Things start to look different from Tuesday the 22nd. We get a 3ft E swell on Tuesday afternoon, but it’s onshore with a rain shower, so it’s choppy and ugly. Wednesday the 23rd sees the swell build. Morning is 4ft from the NE, but the wind is onshore at 12 mph and it’s raining. By the afternoon, it jumps to 6ft from the NE with a 6-second period. The combined energy is now 227, moderate. But the onshore wind is 19 mph, so it’s a blown-out mess. This is getting into expert-only territory in terms of size, but the quality is poor.
Thursday the 24th stays similar: 6ft NE swell with onshore wind, moderate energy of 234. Not good. Friday the 25th is a bit smaller at 5ft NE, but still onshore. Saturday the 26th drops back to 4ft, but again, onshore wind. The wind never lets up.
Sunday the 27th is the biggest we see. A 7ft SE swell arrives in the afternoon with a 7-second period. The combined energy jumps to 423, which is strong. But the wind is onshore from the NNE at 19 mph. That’s big, messy, and only for experts, and even then it’ll be a battle.
Monday the 28th stays chunky with a 4ft SE swell and 242 energy, but the wind is cross-on. Not great.
Finally, on Tuesday the 29th, we get a break in the wind. Morning sees a 4ft ENE swell with an 8-second period, 157 combined energy, and a light offshore from the SW. It’s described as surfable but ordinary. This is the closest we get to a clean session, but the swell is small and a bit weak.
Overall, there are no standouts here. The wind is almost always wrong for this spot, and the swell windows don’t line up. For a reef that needs a specific NE swell with offshore wind, this 16-day run is a write-off. You might get a clean but tiny wave on Tuesday the 29th morning, but don’t hold your breath. The long gaps with nothing are pretty normal for a spot that’s this picky.

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.
