The Lowdown
G’day, Rusty here. We’ve got a bit of a mixed bag coming our way over the next couple of weeks at Austinmer Beach. The first few days are only offering small, marginal waves, so we’ll be waiting for a couple of standout sessions, especially mid-week and into the following weekend.
The water temp is sitting at 64°, which is about average for this time of year. Not worth a second thought.
Saturday the 12th is the best bet early on. We’ve got a clean, light offshore breeze out of the N, and a 3ft SSE swell rolling in with an 11-second period. It’s a groundswell with moderate energy (348), so those sets will have a bit of push, but the shape should be good for a beginner-friendly wave. Expect some company though – crowds are sometimes an issue here.
Sunday the 13th drops off quickly, with small, weak wind-affected surf. Not worth paddling out. Monday the 14th sees a brief improvement mid-morning, with a light cross-offshore breeze and a small 4ft swell from the NE, but the period is short (7 seconds) so the waves will be fat and weak. Tuesday the 15th is poor, with onshore winds and chop.
Now, Wednesday the 16th morning is a real standout for the experts only. We’ve got a solid 8ft S swell at 9 seconds whipping up a huge combined energy of 1203. That’s serious power. The wind is a fresh cross-shore out of the SSW, and the break is exposed, but the swell is predicted to be too big for this spot. This is strictly for experienced surfers, and I’d say it looks more like a day for kite surfing than paddling in. Thursday the 17th morning is similar – another 8ft S swell (1155 energy) – but still too big and lumpy for most.
We get a nice reset on Friday the 18th morning, with a glassy light NNW offshore (almost calm), and a 3ft S swell with an 8-second period. The energy is moderate (221). It’ll be clean and small, fun for a longboard.
The real gem for the whole outlook might just be Saturday the 19th morning. The wind goes dead calm – glassy conditions with zero wind. A 3ft ESE groundswell with an 11-second period, energy at 205. That’s a long period swell for a beach break – it could break a bit straight, but with the glassy surface and clean little peaks, it’s going to be a lovely morning for a paddle.
After that, things drop right off. From Sunday the 20th all the way through to the end of the window, it’s mostly tiny or onshore mush. There’s a small bump on Friday the 25th morning with a 5ft NE swell (272 energy), but the period is short (7 seconds) and the wind is cross-shore. Only ordinary.
Bottom line: the first couple of days offer a clean but small start. The mid-week big swell is for experts and kiters only. Saturday the 19th morning is the pick of the bunch – glassy, clean, and a proper long-period groundswell. Get out there for that one.
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.

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.
