The Lowdown
Alright, let’s break it down in feet and miles.
First off, the start is a total washout. Monday the 17th is a gale-force mess with 30 mph winds and 15-foot slop. Forget it. Tuesday the 18th is a bit better but still cross-on with a 12-foot, 16-second swell that’s messy. The first real window is Thursday the 20th.
Thursday morning, the 20th of August, is the big one. The north wind drops to a glassy 3 mph, with an 8-foot swell from the WSW and a long 16-second period. The energy is strong (3594). This is for experts only—anything over 8 feet is serious. Water temp is about 64°F, normal for this time of year.
Friday the 21st morning is another cracker. Clean offshore wind from the SE at 6 mph, with the swell easing to 7 feet but still a very long 15-second period (2048). That’s your pick for the first week.
Saturday the 22nd afternoon is glassy again with a 6-foot, 16-second groundswell from the WSW. That’s a bit more manageable for the average surfer, but still a strong wave.
Then we hit a lull. Sunday the 23rd and Monday the 24th are choppy and poor.
The next real chance is Tuesday the 25th morning. A clean 10-foot swell from the WSW with a moderate 14-second period (3375). The wind is cross-off from the south, so it’s clean, but big.
Wednesday the 26th morning is glassy with a 7-foot, 16-second swell from the WSW (2368). Solid, clean. The best of the second week is Friday the 28th afternoon. Light offshore wind from the south, 7-foot, 15-second groundswell (2484). Clean and powerful.
A big, dirty swell hits on the 30th and 31st with strong onshore winds and 8-foot+ waves. The 1st of September is a no-go: 13-foot swell with howling wind. Storm surf.
The standout: Thursday the 20th (morning) and Friday the 21st (morning) are your best bets. Glassy or clean offshore, solid groundswell, quality waves. If you’re experienced, get on it.

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.
