The Lowdown
Alright, Rusty here. Let’s break it down.
First up, the outlook for Avalon-North (point break). We’ve got a bit of a flat spell to start, but don’t write it off just yet. The best window in this whole 16-day forecast is shaping up to be Friday morning, the 28th of August. That’s the one to circle. We’re looking at a clean, glassy morning with a 5ft SSE swell running at 11 seconds. That’s a nice, long period groundswell with solid energy (667), and with the wind glassy, it’s going to be smooth. The swell direction is from the SSE, which is a good match for this spot. It’s a consistent point break, so expect some proper lines, but it’s an advanced wave, so only take it on if you’ve got the experience. The water temp is about average for the time of year, so nothing unusual there.
The week before that is pretty quiet. Wednesday the 26th and Thursday the 27th are small and messy, with poor conditions and weak energy. Don’t bother. Saturday the 29th has a bit of size (5ft) but the wind is cross or cross-on, and the energy is moderate (391), so it’s only marginal. You might get a couple if you’re desperate, but it’s not special.
After Friday’s standout, things drop off again. Sunday the 30th has a tiny 2ft swell with offshore wind in the morning, but it’s weak (124) and ordinary. Then from Monday the 31st all the way through to Thursday the 10th of September, we’re into a long, flat run. Swell heights are mostly below 2ft, with energy readings in the teens or low twenties. There’s a brief spike on Saturday the 5th of September with a 5ft S swell, but it’s short period (6 seconds) and cross-shore wind, making it choppy and poor. Not worth the paddle.
So, the verdict: there’s a real standout on Friday the 28th of August, but the rest of the 16 days are mostly a write-off. If you’re not on it that Friday morning, you’ll be waiting a long time for the next decent wave.
Rusty, signing off.

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.
