The Lowdown

G’day, Rusty here. Looking at the 16-day window for Little Avalon, it’s a pretty slow start with a whole lot of nothing before things finally show some life. You’re looking at nearly a week and a half of flat or junk conditions before a real window opens up. The water temp is sitting around 64°, bang on average for this time of year, so no surprises there.

We kick off Wednesday the 16th with a tiny 0.7 ft swell from the ENE, but a strong 22 mph southerly cross-off wind is just ruining it – poor surf, no point even looking. Thursday the 17th stays flat with 0.3 ft waves and a similar story. Friday the 18th morning is actually the first hint of hope: the wind goes glassy, dead calm, and there’s a tiny 2 ft swell from the SE with a short 7-second period. The combined energy is weak at (54), but it’s clean and surfable. It’s ordinary, but a dawny could be fun on a mal. That window closes fast though – by afternoon the onshore NE wind kills it.

Saturday the 19th is flat, Sunday the 20th is flat again with a tiny bit of onshore junk, Monday the 21st is tiny and weak, and Tuesday the 22nd is wet and flat. This is a long, dry spell.

Finally, we get a pulse on Wednesday the 23rd. The swell jumps to 5 ft from the east with a period of just 6 seconds, so it’s short-period, building to 6 ft in the afternoon. Combined energy climbs into the moderate range (202 and 240). But the wind is onshore from the NNE and NE, making it messy. This is more of a kite-surfing setup than a clean paddle session – not for beginners either as it’s over 5 ft. Thursday the 24th stays similar, with 5 ft to 6 ft of short-period NE swell and onshore wind – still rough.

Now, the standout window. Friday the 25th morning sees a shift: the wind turns offshore from the SSW at 12 mph, with a 3 ft swell from the ENE, period 7 seconds, and combined energy of (93). It’s surfable and clean, with moderate offshore wind keeping things tidy. That’s your first decent option.

But the real gem in this forecast is Wednesday the 30th of September morning. The wind goes glassy, dead calm, with a 4 ft swell from the ENE, period 8 seconds. Combined energy is solid at (213), and the conditions are expected to be good. This is a reef break, so that longer-period wave will shape up nicely. It’s on the smaller side of moderate, so very manageable for most. Crowds are “often” here, so expect company.

Thursday the 1st of October morning stays clean with a glassy NNW wind, 3 ft ENE swell, and combined energy at (103), but it’s ordinary. The action really peaks on that Wednesday morning.

All in all, don’t bother with the first 9 days. Friday the 25th gives a clean offshore session, but the big standout is Wednesday the 30th September morning – glassy, clean, and a proper little east swell. Circle that date.

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.
