The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up for our stretch of coast. We’ve got a bit of a mixed bag over the next couple of weeks, but there’s a couple of lights in the tunnel if you can read the ocean right.
We’re starting off a bit slow, but there’s a couple of windows. The water temp is sitting about average for this time of year, so nothing to write home about, just normal winter/spring gear.
The best of the early going is looking like Friday morning, August 14th at Austinmer Beach. It’s not massive, S swell at a modest 3ft, but the wind is dead flat – glass. That means clean, smooth lines. It’s a great session for the beginner crowd, the energy is moderate (200 combined energy), and with a shorter period you won’t be waiting around for stacks and stacks. It’s small but perfectly workable. Could get a little busy since crowds are possible here, but for a Friday morning, it’s the pick of the first week.
Skip the weekend. The 15th and 16th get messy with rain and cross-shore winds, and the waves get chopped up. The swell bumps around the 5ft mark but the period drops right off to 6-7 seconds, so it’s just bumpy, weak junk.
Now, for those of you who can wait, keep an eye on Thursday morning, August 20th. The swell jumps up to 8ft from the E, with a combined energy of 1304 (strong). That’s proper juice. However, that is too much wave for this break – it's a beginner-friendly spot, so this one is ruled out for the average punter. The conditions are technically favourable but the size is just too much. This is a bigger-wave day, only for watermen who really know the bank.
The real standout, the absolute pick of the whole 16-day run, is Friday morning, August 21st. We’ve got a 6ft E swell with a 9-second period, and you guessed it – glassy conditions again with an ENE wind that’s nothing. Combine that with a solid energy level (603) and you’ve got a window of nice, clean, punchy surf. This is the one to circle on the calendar. It’s the best balance of size, power and cleanliness we are going to get.
The following week looks more consistent but smaller, with clean conditions on the 22nd and 23rd mornings, but the standout remains that Friday the 21st.
So, the call: Friday August 21st morning is your top tier session. For a smaller, more manageable wave, Friday August 14th morning’s glass-off is the one.
Stay frothy,
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.
