The Lowdown
G’day, Rusty here. Look, I’ve been over the charts for Austinmer Beach, and I’m not gonna sugarcoat it—this 16-day window starts out real flat and stays that way for a long time. We got a couple of days that’ll get your attention, but you’ll be waiting.
The first real chance to get wet doesn’t come until Tuesday, August 25th. For over a week before that, it’s mostly knee-high slop or ankle-biters with onshore junk and combined swell energy mostly under 200, often way down in the double digits. Then, on Tuesday morning, a 5ft SSE swell rolls in with an 8-second period. The wind is glassy—dead calm. That’s a big deal, makes it clean as a whistle. The combined energy hits 425, a solid moderate reading. It’s short period, so a bit fat and sectiony, but it’s the clear best of the run. Wednesday the 26th of August morning is another one. A clean 3ft S swell with an 11-second period and a WNW wind blowing offshore at 15 mph. That’s proper grooming. Energy is 350. The afternoon gets gusty at 22 mph from the W, still offshore but strong, so clean but tricky.
Through the first week, from August 17th to the 24th, it’s grim. Small, messy, and weak. Then after the 25th and 26th, it drops back to 1ft to 3ft junk with weak energy and tricky winds. Saturday the 29th of August morning shows a clean 3ft ENE swell with a WNW offshore, but the period is only 6 seconds and energy is just 116—weak and windswelly.
If you’re a beginner, that 5ft on the 25th might be a bit much, but for everyone else it’s the pick. Austinmer Beach is an exposed beach break, so a longer period groundswell (like that 11-second on the 26th) can run a bit straight, but with offshore wind I’d still be keen.
Water temp is pretty normal for this time of year, no anomaly worth talking about.
Crowds can pop up sometimes, but on a Tuesday in late winter, you should have plenty of space.
There’s a big ol’ gap of no real surf from the 17th until the 25th, so if you can’t wait, don’t bother checking till that Tuesday.
Rusty.

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