The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead, and while it takes a little while to really fire, there’s some quality on the table.
The first real action kicks off on Monday, 20 July, at Austinmer Beach. It’s a beginner-friendly spot, but don’t let that fool you—this is where the goods start. The water’s sitting at 65°, which is a touch warmer than usual for this time of year, so you’ll notice that. Monday morning brings a clean 5ft swell from the ENE, with a period of 11 seconds, and a light cross-offshore breeze from the NW. The energy is moderate (723), and conditions are looking very good. This is a standout for the early part of the week. The breeze stays light, and the waves will have decent shape. It might get a little busy though—crowds are sometimes a factor here.
Tuesday morning, 21 July, is still clean with a 4ft ENE swell, but the energy drops a bit (387). Still good, but not as punchy. Wednesday morning, 22 July, the wind turns offshore from the W, and the swell drops to 3ft. It’s clean, but you’ll be hunting for the better sets.
Thursday, 23 July, is a write-off. Small, weak, and messy. Energy is down in the double digits (83). Leave the board at home.
Friday, 24 July, things get interesting again. The morning brings a 5ft swell from the S, with an 8-second period. The wind is light offshore from the WNW, and the energy is moderate (312). It’s a short period, so expect a bit of a bumpy, close-interval wave. Not a standout, but it’s surfable. The afternoon throws up a strange one: a tiny 1ft swell from the SSE with a very long period of 18 seconds. That’s groundswell, and at a beach break, it’ll likely close out or break straight. Not great for here.
Saturday, 25 July, is a bit messy with moderate cross-offshore winds. The swell builds to 3ft from the S, but the quality is marginal.
Sunday, 26 July, the swell is 5ft from the S, but the wind is cross-shore, and the conditions are a bit choppy. Not the best.
Now, here’s the real standout. On Monday, 27 July, the morning is glassy. Flat calm. The swell is 4ft from the SSE, with a 10-second period. The energy is moderate (285), and the wind is dead calm from the NW. This is as clean as it gets. If you can get out there, this is the session to aim for in the first week.
The next few days have some clean offshore windows, but the swell is small. Tuesday, 28 July, has a 3ft S swell with a moderate offshore breeze—clean, but not much push.
But then, hold onto your board. Thursday, 30 July, the energy goes nuclear. The morning sees a 5ft SSE swell with a very long period of 15 seconds, and the energy is through the roof (1973). The wind is gentle cross-shore. This is a big, powerful groundswell. The afternoon is even bigger: 8ft from the SSE, with a period of 12 seconds, and energy at 2644. That’s strong to very strong energy. This is only for experts. That size and power at a beach break like Austinmer will be heavy, and the onshore wind will make it lumpy. A real challenge.
Friday, 31 July, the swell drops to 6ft, still from the SSE. It’s on the big side, but the wind is light cross-shore in the morning. Still a big wave, but a bit more manageable.
The final standout is on Saturday, 1 August. The morning is glassy again, with a 6ft SSE swell and a 12-second period, and energy at 876. This is a beautiful morning. Clean, solid, and powerful. A great way to kick off August. The afternoon turns onshore, so get it early.
After that, the swell fades and the wind gets messy. The second week is a bit of a letdown compared to that late July/early August burst. Small, choppy, and not worth stretching the wetsuit for.
Overall, the best on offer is the glassy morning on Monday, 27 July, for clean, fun waves, and the big, powerful morning on Saturday, 1 August, for the advanced crew. The Thursday, 30 July, session is for the brave only. Don’t sleep on that Monday morning glass.
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.

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.
