The Lowdown
Alright, Rusty here again. Let’s talk about Little Avalon in feet and Fahrenheit.
Right now, there’s not much happening for a good stretch. The forecast kicks off with a few days of small, onshore wind mess, so the first real window to keep an eye on doesn’t come until Saturday, September 26th. That’s about two weeks out, so it’s a bit of a wait, but there’s something to get a bit hopeful about.
Leading up to that, the pattern is mostly poor. From Sunday the 13th right through to the end of the third week, we’ve got tiny swell, choppy conditions, and not enough energy to get you excited. The energy readings are mostly in the low double digits or less, which tells you it’s weak. The water temperature sits around 64°F, which is about normal for the time of year.
The one standout worth pointing to is Saturday, September 26th – morning session. Little Avalon should see a 6 ft groundswell from the NE, with a period of 9 seconds, and the wind is glassy. That is clean, lined-up, and surfable. The combined energy jumps to 429, so there’s proper push in the water. That size is okay for advanced surfers, but anything over 5 ft can be a bit much for beginners, so keep that in mind. The offshore wind is from the SSW, light, and it’s glassy. That’s a major positive for quality. The break itself is a reef setup, very consistent, and the swell direction from the NE matches the optimum direction, so the waves should set up nicely. Expect clean conditions and good shape. Crowds are often here, so don’t expect to have it to yourself.
Before that, on Thursday the 24th and Friday the 25th, the swell builds but conditions are rougher – strong cross-offshore winds, rain showers, and the surf quality is marginal. The energy climbs, but the wind and tide aren’t cooperating for a clean session. It’s more of a look-and-see window for the dedicated.
After the Saturday morning highlight, the swell drops off quickly on Sunday the 27th and Monday the 28th, with onshore winds returning and poor conditions again. So that Saturday window is your best bet by a long shot.
Overall, there’s a big quiet spell from now until late September, then one clear glassy morning that stands out as the pick of the forecast. Keep an eye on that Saturday.
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.
