The Lowdown
Alright, let’s take a look at Austinmer Beach over the next couple of weeks.
Right off the bat, there’s some clean, small surf on offer for the Sunday morning. We’ve got a south swell at 3 ft with a 10-second period, a light cross-off breeze from the NNE at 6 mph. The water’s sitting around 64°, which is pretty average for this time of year – nothing wild going on there. Wave energy is moderate, around the 206 mark. It’s a beginner-friendly spot and the conditions should be tidy, making for a decent little session if you’re just looking to get wet. Keep in mind, crowds are possible around here.
Now, that Sunday arvo, the wind swings NE and picks up, the swell drops a touch and the quality goes downhill. Monday morning brings a bit more south swell, 2 ft at 11 seconds, cross-off NW breeze again – it’s surfable, but nothing to write home about. The real story starts on Wednesday the 16th. By Wednesday morning, the swell pumps up to 8 ft from the south with a 9-second period, but the wind is a fresh cross-shore from the SSW at 19 mph. The wave energy is cranking – we’re talking 1212, which is strong – but that’s just too much size for this break. It’s big enough to be expert-only territory, and honestly, with that wind, it’s gonna be a lumpy mess. Same deal Wednesday arvo and into Thursday: 10 ft to 12 ft south swell, but it’s cross-onshore or cross, and the energy numbers are through the roof (2337, 1628) – again, too big for this spot.
Things settle down for Friday the 18th. That morning is the standout of the whole outlook. We’ve got a 4 ft ESE swell, 10-second period, and glassy conditions with a light NW breeze at 3 mph. Wave energy is solid at 469, and the word is good surf conditions. That’s your window – clean, lined up, and accessible for a good range of surfers. Saturday the 19th morning is also looking nice: 3 ft ESE swell, 11-second period, glassy again with a light SW breeze. That’s a close second, but Friday morning has the edge with a bit more size.
After that, it’s a long, slow fade. From Saturday arvo all the way through to the end of the 16 days, it’s mostly tiny, weak, or windy. There’s a stretch from the 20th to the 24th where it’s either below 3 ft with short periods, or the wind is howling onshore. Monday the 21st has a 5 ft south swell but with a fresh cross-shore and only a 6-second period – that’s just slop with onshore push, no good for a paddle. The morning of the 24th shows a glassy 2 ft ENE swell but it’s short period at 6 seconds, so it’s pretty ordinary. The final days (25th to 28th) see more small, short-period swell and mostly cross-onshore winds, with the 28th bringing rain and a fresh cross-onshore – definitely not one to circle.
So, bottom line: if you can, get out Friday morning the 18th. That’s your best bet for a clean, fun wave at Austinmer. Saturday morning the 19th is a solid backup. The rest is either too big, too small, too windy, or just plain flat. There’s about a 5-day gap of poor options from the 20th onward, so don’t hold your breath.

Information about the Austinmer Beach Surf forecast

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.
