The Lowdown
Alright, grab a coffee, mate. Rusty here, talking about Avalon Point. We've got a two-part story in the charts. The next few days are a bit of a mixed bag, but the real magic is a way off.
Thursday the 20th kicks off with a solid 8-foot swell from the WSW, with a 16-second period and a hefty combined energy of 2958. But that cross-shore wind from the SSW is going to put a bit of a wrinkle on it.
Now, Friday the 21st morning is a beauty. The swell drops to a bit over 7 feet, still from the WSW, a 15-second period, and the energy is a solid 2120. The real winner is the glassy condition with a light breeze from the ESE. That's offshore, and it's going to be clean. The water temp is 64.8°, which is pretty average for the season. This is a real window for the experienced crew.
Saturday the 22nd morning is also a gem. The swell is 6.5 feet, WSW, 16-second period, and the energy is 2068. The wind is dead calm, glassy. That's a beautiful, clean lineup. But the afternoon? The wind will swing to the SSW, get up to 15 mph, and turn it into a lumpy mess. Sunday is a wipeout with that 18 mph cross-shore wind.
Then there's a bit of a lull. The wind is messy for a few days. Monday the 24th morning is glassy with a 6.5-foot, 14-second period swell and energy of 1570, but the wind is from the NNE, which is a bit cross-on. Not the best for Avalon.
But hold on. Wednesday the 26th of August is the standout. The charts are lit up. We're looking at a massive 13-foot swell from the WSW, but with a 19-second period. The combined energy is a colossal 10481. That's a serious amount of water moving. The wind is a light offshore from the SE, keeping it glassy. This is big, deep, powerful groundswell. At over 8 feet, it's strictly for experts, and for a point break like Avalon, that long period will be rewarding with some incredibly long, walling waves. The afternoon stays solid at 11.5 feet with a 19-second period and energy of 8363, with a clean cross-off breeze.
The following days are still big, with 10-foot+ swell, but the wind is a bit stronger, so it's not as perfect. The energy stays high, like 4117 on the 27th, but the wind is a moderate breeze.
Further out, around the 30th of August into September, we see another pulse of 10-foot-plus swell, but the wind is cross-on, which is a real shame. There's a chance on the morning of Tuesday the 1st of September with a 10-foot, 14-second period swell and glassy conditions, but crowds are *often* here, so don't expect a quiet lineup.
The real standout is the 26th of August. That's the one. It's a long way off, so the forecast could shift, but if it holds, that's a day for the books. The rest of the window is a mix of messy wind and solid swell, which is more of a choose-your-window situation.

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