The Lowdown
Alright, this is Rusty, and I’m looking at the forecast for Avalon-North. Right off the bat, I gotta be straight with you: the next few days are looking pretty grim. The combined swell energy is tiny at first, around 49 (weak), and we’ve got poor surf conditions. It’s not gonna be worth paddling out.
We’ve got a bit of a dry spell until Monday morning the 10th, when the swell starts to show some life. That morning, we’re looking at a 7ft swell from the ENE with a period of 9 seconds, and the combined energy jumps to 688 (moderate to strong). The wind is cross-off from the NW at 19 mph, keeping things clean. That’s going to be a solid, punchy wave, but at 7ft, it’s getting into the territory where it’s better for experienced surfers—beginners might find it a bit much. The water temperature is about average for this time of year.
The best action is shaping up for Saturday morning, the 22nd of August. That’s the standout. Swell is 4ft from the ENE, period of 9 seconds, and the combined energy is 289 (moderate). The wind is offshore from the W at 9 mph, so it’s going to be clean and glassy. That’s a proper session, with gentle offshore winds and the swell direction matching the optimum from the ENE. Expect some good, lined-up waves at this point break. Crowds are likely here, so get in early.
The middle of the second week has some interest, but it’s less certain. Thursday morning the 20th brings a 6ft ESE swell with 8-second period, but the wind is cross-shore and the conditions are choppy. Friday the 21st is a bit better with a glassy afternoon, but the swell is smaller. Overall, the best bet is that Saturday the 22nd—it’s the one to circle on the calendar.
Stay stoked, and I’ll see you out there.

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.
