The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming down the pipe for our stretch of coast.
We’ve got a solid run of surf kicking off this Friday, the 21st of August, and it’s going to be a bumpy, powerful ride for a few days. The standout is definitely Friday morning and the following Wednesday morning. These are the ones to circle on the calendar.
Friday morning at Middleton Beach, we’ve got a clean 10ft swell pushing in from the SW, with a long 15-second period, and the wind is a light offshore from the NW. The water is 64°, which is a touch warmer than normal for this time of year. The combined energy is massive at 4543, so there’s a heap of power in the water. This is proper groundswell. For experienced surfers, this is excellent. The long period means it’ll be lining up nicely, but with that size, it’s going to be powerful and strictly for those who know what they’re doing. The offshore wind is a major plus, you’ll be looking at clean, steep faces.
Friday afternoon the wind swings onshore from the ESE, making things a bit sloppy. Saturday morning stays clean with a cross-offshore breeze and a 8ft SSW swell, still plenty of energy. Sunday morning gets a bit messy with a cross-shore wind, so I’d give it a miss.
Now, the real standout for the big wave crew is Wednesday, the 26th of August. Wednesday morning delivers a pumping 13ft SW swell with an incredible 18-second period. The wind is a gentle offshore from the NW, and the combined energy is through the roof at 11514. This is a very long period groundswell with extreme power. It’s going to be a serious, heaving wall of water. This is not for the faint-hearted; only experts should be out there. The long period will make it break with real authority.
Thursday the 27th is still chunky, with a 15ft swell but strong cross-offshore winds, which makes it a bit of a battle. It’s still big, but the quality drops.
There’s a lull in the quality after that. Friday the 28th and Saturday the 29th are poor, with onshore winds and shorter period swells. Sunday the 30th and Monday the 31st see a return to 8ft to 10ft swells, but the wind picks up, so it’s not the cleanest. The best of that second week looks like Tuesday, the 1st of September. Tuesday morning has a 7ft SW swell with a 15-second period and a clean offshore wind from the WNW. It’s a solid, clean option, but not as big as the earlier standout.
By Wednesday the 2nd, the wind is howling offshore at 25 mph, making it very hard to paddle into, even with a clean 6ft swell. The last few days of the forecast show some big, windy swells, but the quality is marginal. Saturday the 5th of September has a 18ft swell, but it's blown out and messy.
Bottom line: If you want the absolute best, get on it Friday morning the 21st, or if you’re an expert looking for a beast, Wednesday morning the 26th is the one. The rest of the run is a bit of a mixed bag, with clean windows but often fighting the wind. The crowds at Middleton can be a thing sometimes, but with these sizes, the lineup will thin out to just the keen crew.
Rusty.

Information about the Middleton Beach Surf forecast
The above surf forecast table for Middleton Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Middleton Beach can be found by selecting the local surf guide option on the grey menu. Our Middleton 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 (Middleton 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 Middleton 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.
Middleton Beach is 8 km (5 miles) from Albany. If you plan a holiday in Far South of Western Australia, look for hotels and other accommodation in Albany. Albany has rooms for a wide range of budgets as well as car hire and transport links.
