The Lowdown
Alright, Rusty here again, but in feet and knots.
We’re looking at a pretty grim run for the next week and a half. The first ten days or so are just tiny, messy, wind-chopped slop. Combined energy numbers mostly stay weak, way down in the double digits or low triple digits, with nothing worth getting wet for. You’ve got small, weak swells and cross-shore winds from Monday 17 August all the way through.
The water temp sits around 64°, which is about average for this time of year.
Then, on the morning of Friday 28 August, things finally turn. Austinmer Beach pulls a solid 6ft NE swell with glassy conditions and the combined energy hits 688—that’s strong. The period is short, 8 seconds, but with zero wind and clean lines, the walls will stand up. This one’s for experienced crew, as it’s getting solid. If you’re not confident in the bigger stuff, sit this one out. The afternoon pushes the swell to nearly 7ft (combined energy 811) but the wind swings cross-onshore and the quality drops—no good.
After that, we’re back to small, onshore rubbish again for the remaining days. No other standout in the 16-day window.
It’s a long stretch of quiet, but the ocean can turn around quick. We’ll see what happens.
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.
