The Lowdown
Alright folks, Rusty here. Let's get into it.
We've got a run coming up that starts off a bit raw and winds up with some absolute crackers. The pattern for the next two weeks is all about the Southern Ocean firing up, throwing consistent, powerful SW groundswells our way. The wind looks set to play ball on quite a few days, especially in the mornings. There's a solid stretch of big, clean surf building towards the end of the month, which is where the real magic happens. But let's walk through it.
The first one to get the nod is Thursday the 21st of August. It's a morning mission, clear skies, and a very light NW breeze keeping things cross-off. We're looking at a solid 10ft of SW groundswell with a generous 15-second period. The combined swell energy is pumping at 4543 (moderate to strong). That's a powerful, well-ordered groundswell for Middleton Beach. It's a substantial swell—over 5ft—so it's beyond the rookie zone, but for experienced surfers, the conditions are rated excellent. The water temp is 64°, which feels a touch warmer than normal for this time of year, so you might get away with just a spring suit.
Things go a bit ragged from the weekend (23rd) through to the middle of the following week, with strong onshore winds and lumpy conditions. That period from Sunday morning until Tuesday afternoon is a write-off, a solid few days of pretty average stuff. But sit tight.
The real standout is Wednesday the 26th of August. The morning session is where it's at. We've got a massive 15ft of SW swell rolling in with a very long 19-second period. The combined energy is off the chart at 13877 (very strong). That's a serious, ground-breaking ocean swell. For clearer context, for Middleton Beach, a wave height over 8ft is expert territory only. This is huge. The wind is a light offshore from the WNW, keeping it clean. This is a day for the experienced crew only—the size and power demand respect, and the long period means it could be a bit straight for the beach, but with that offshore wind, the main banks should hold some proper barrels. This is the pick of the whole outlook. By the afternoon, a fresh SW cross-shore kicks in and makes it lumpy, so hit it at first light.
It cleans up again beautifully for the last few days of August and the start of September. The morning of Sunday the 30th of August offers another brilliant session; a clean 10ft swell with a 19-second period and a strong offshore NW wind. The energy is massive at 6729. Then Monday the 31st of August morning is also a cracker: 13ft of SW swell, 16-second period, light offshore WNW wind and an enormous energy of 12993. It’s another expert-only day that will be absolutely pumping if the banks hold.
Overall, the best of the best is undeniably the morning of Wednesday the 26th of August. Get in the water early, paddle out at the peak with the most shape, and hold on. The consistent, clean, and powerful swells from the 30th onwards offer a fantastic end to the outlook as well.

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.
