The Lowdown
G’day, Rusty here. Let’s talk about Austinmer Beach in feet and miles per hour, because that’s how some of us like it. Water’s about 64°F, pretty normal for late August.
The pick of the litter is Thursday morning, August 27th. You’ll get clean 6ft waves out of the south, dead glassy on the water. Combined energy is 528 – that’s a solid moderate push – with a 9-second period. This is your session. Right behind it is Friday morning the 28th: 5ft from the south-southeast, period hitting 11 seconds, and a light cross-off breeze keeping things tidy. Energy climbs to 630. That SSE direction is exactly what this beach likes.
Let’s run through the days. Tuesday the 25th has a 4ft NE swell in the morning with a light breeze – rideable but short 6-second period. Afternoon bumps to 5ft but rain moves in. Wednesday the 26th is blown to bits with strong cross and onshore winds. Forget it.
Saturday morning the 29th goes glassy with 4ft from the SSE – fun little window. Sunday the 30th and Monday the 31st are mostly poor, though Monday morning has a tiny 2ft wave with a very long 17-second period. Fine for a reef, not so much for a beachie.
Into September, Tuesday the 1st has clean knee-high waves with energy dropping. Wednesday and Thursday get even smaller – energy down to 69 on Thursday the 3rd. Friday the 4th sees a 4ft pulse but it’s onshore and chunky. The second week is mostly flat or ugly, with only a tiny glassy morning on Tuesday the 8th worth checking: 2ft from the south, 12-second period, energy 273.
If you’re after windsurfing or kiting, some of those moderate onshore days mid-week could work. For the regular surfer, it’s all about that Thursday morning. Don’t miss it. 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.
