The Lowdown
G’day folks, Rusty here. Let’s talk about what’s on offer for Avalon-North. This is a point break, so it can handle a bit of direction, but we’re looking at a patchy run over the next couple of weeks. There’s a real gap at the start – nothing worth paddling out for until Saturday the 29th, and even then, it’s a one-hit wonder.
The standout window is this coming Saturday morning, the 29th of August. We’ve got a clean 4ft SSE swell sliding in with a 10-second period, and the wind is a light cross-off at 3 mph from the SSW. That’s about as good as it gets for this break – the wave energy is moderate (298) and the conditions look seriously good. Expect some fun, lined-up waves, but be warned: this spot can get crowded, and Saturday is likely to draw a few locals.
After that, it’s a flat spell. Sunday morning the 30th has a glassy 2ft SE swell, but it’s weak (117) and won’t offer much. Then from Sunday arvo all the way through to Tuesday the 8th of September, we’re looking at tiny, weak junk – nothing over 1ft, and mostly poor surf conditions. That’s a solid 9-day lull, so don’t get your hopes up.
Now, looking further out, there’s a flicker of something on Wednesday the 9th of September morning. An 8ft SSE swell rolls in with a 10-second period, and the wave energy is very strong (1186). But it’s a tricky one – the wind is a moderate cross-off at 16 mph from the WSW, and the forecast flags it as marginal due to tide. That size is for experienced surfers only; 8ft is solid and powerful. Thursday the 10th sees a similar 8ft SSE swell, but with a fresh 22 mph SSW cross-off wind, it’ll be messy and only for the brave.
The true second standout, and the best bet if you can wait, is Friday the 11th of September morning. A clean 5ft SSE groundswell with a 10-second period, light offshore WNW wind at 6 mph, and moderate-to-strong wave energy (556). That’s a recipe for clean, punchy waves at this point. Saturday the 12th morning is also good – 5ft SSE, offshore WSW wind, and moderate energy (382). Both of these are a solid 10 days out, so keep an eye on the forecast – they’re promising but not locked in.
Overall, if you’re chasing the best, hit Saturday morning the 29th, or pencil in Friday the 11th. The water temp is about average for this time of year, nothing weird going on.
Rusty.

Information about the Avalon-North Surf forecast
The above surf forecast table for Avalon-North provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Avalon-North can be found by selecting the local surf guide option on the grey menu. Our Avalon-North 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 (Avalon-North) 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 Avalon-North 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.
