The Lowdown
Alright folks, Rusty here. Let's break down what we've got coming up. It's a bit of a slow start, but there's some serious potential hiding in the back half of the forecast.
First up, we're looking at Middleton Beach. It's a sheltered spot, which means it needs the right swell direction to really work, and it's inconsistent, so you've got to pick your moments. The water's sitting at 64°, which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.
The action kicks off on Monday the 17th of August. It's not the best start – we've got a solid 8 ft SW groundswell (17-second period) with a strong offshore wind, but it's a howling 25 mph. That'll be clean but a real battle to get out. The energy is pumping (3873), but it's more of a suffer-fest than a fun session.
Things start to look up on Tuesday the 18th. The swell drops slightly to 8 ft, but the wind switches to a gentle offshore breeze at 9 mph. That's the sweet spot – clean, manageable, and the swell energy is still solid (3149). Tuesday afternoon keeps the good run going with a moderate offshore. This is where you want to be.
The real standout, though, is Wednesday the 19th of August. Check this out: 12 ft of SW groundswell (16 seconds) with the combined energy cranking at 6127. But the kicker? The wind goes glassy – 3 mph from the SSE. That's about as perfect as it gets for the experienced crew. This is for the guys who can handle some size, but it's going to be absolutely firing. The Thursday morning session on the 20th is also a solid backup with a clean 12 ft swell and a moderate offshore.
Now, the forecast gets a bit messy from Friday the 21st through the weekend. The swell drops, the wind goes cross-shore or cross-onshore, and the quality drops off. We've got a few days of marginal conditions, with the swell bottoming out around 5 ft by Sunday the 23rd. It's a bit of a dead spell.
But don't write it off yet. The second week brings some serious promise. Monday the 24th is a bit mixed, but then Tuesday the 25th of August is a monster. We're looking at a 13 ft SW groundswell with an 18-second period and the combined energy exploding at 11217. That's a lot of water moving. The wind is cross-offshore, so it'll be clean, but I'm telling you, that is a big, powerful ocean. Only the experts need apply. The energy remains high through the 26th and 27th, but the quality drops back to marginal.
Looking further out, the weekend of the 29th and 30th of August shows some promise. The 30th of August is worth a mention: an 8 ft SW groundswell, 18-second period, combined energy of 4759, and a gentle offshore wind. It's a much more manageable size and the conditions look excellent for experienced surfers.
The very end of the window, into the 1st of September, is a bit of a write-off with strong winds again. So, to sum it up: the first real standout is Wednesday the 19th with that glassy 12 ft swell. The second big event is the massive 13 ft swell on Tuesday the 25th, but that's for the hardcore crew only. Keep an eye on the 30th of August as a nice, clean option in the second week.
Rusty, signing off.

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.
