The Lowdown
G’day, Rusty here with the lowdown on Austinmer Beach for the coming weeks.
It’s a slow burn to start. The first week is mostly small and messy, with cross-shore winds keeping things choppy. You’ll need to be patient because the good stuff doesn’t show up until the second week.
From Sunday the 16th through the following Saturday, it’s pretty average. There are a few clean moments, like Tuesday the 18th morning with glassy conditions and a tiny 2ft, or Wednesday the 19th morning with a light offshore and 2ft from the ESE. But these are small fries. The energy is weak, with combined swell energy sitting between 115 and 171. Crowds are always a possibility here when it’s small, but there won’t be much to fight over.
The one session that stands out above everything else is Sunday the 23rd of August in the morning. This is the big one. The swell jumps to 8ft from the south, and the wind is a light, clean offshore from the NNW. That’s a proper winter pulse, and the combined swell energy is a massive 1616. This is expert-only territory—too big for beginners. It’s a beach break, and with that south groundswell (period 9 seconds), it could get a bit lumpy and straight. But if you’ve got the guts, this is your morning.
After that, Monday the 24th morning cleans up nicely with 4ft from the south and a sweet WNW offshore wind—crisp and clean. Energy is moderate at 283. Then Tuesday the 25th morning has a glassy 6ft from the south, with energy at 365. Both are solid follow-up days, but tides will be key.
Water temp is about average for the season, nothing unusual.
Quick summary: the first week is a dud for proper waves. The second week fires up, with Sunday the 23rd morning being the standout—big, clean, and powerful, but for experienced surfers only. If you’re keen, you’ll get a good one.
Catch you out there.

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.
