The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
First off, Middleton Beach is the only spot in the frame, and it’s a tricky one. The water’s running a touch warmer than normal for the time of year at 65°. The whole 16-day window is a bit of a mixed bag, with some proper size but not a lot of clean, easy windows. The swell is mainly from the SSW and SW, with some very long-period groundswell in the 15 to 18 second range, which brings a lot of energy but can make the beach break a bit straight and wally. Combined wave energy is moderate to strong, with the biggest numbers hitting around 10,236 (moderate to strong energy) on the 20th of August.
The first real standout is on Thursday, the 20th of August. The morning session sees a solid 13ft SSW groundswell with a 18-second period, and a moderate offshore breeze from the WNW. That’s proper clean conditions for experienced surfers. The wave energy is pumping at 10,236 (strong to very strong). This is a big, powerful swell, over 8ft, so it’s strictly for the crew with some skill. The afternoon holds up with 12ft at 16 seconds and a fresh offshore wind, still clean but a bit more wind.
The next one to circle is Sunday, the 23rd of August. The morning has a 10ft SSW swell, 15-second period, with a light breeze and clean conditions. The combined energy is 4,089 (moderate). That’s a much more manageable size, still a bit of a push, but the light wind makes it look far more user-friendly than the big days. The crowd profile at Middleton Beach is “sometimes,” so expect a few others out, but it’s not a circus.
For the rest of the window, there’s a lot of onshore or cross-offshore wind, and the consistency is listed as “inconsistent.” The spot is also very sheltered, so it needs the right direction. The SSW swell is the optimum, so when it’s from that direction, it’s on. But you’ll have to pick your moments. The first few days have size, but the wind is messy. The 22nd of August has a 15ft SSW swell, but it’s cross-offshore and winds are fresh, meaning it’s going to be a bumpy, challenging beast.
The tail end of the forecast, from the 25th of August onwards, drops off in size and quality, with poor conditions and strong winds, before a final little window on the 26th of August with a smaller 5-5ft swell and offshore winds, but it’s only a “good” setup, not a standout.
So, the pick of the bunch is the morning of the 20th of August for the big-wave chargers, and the morning of the 23rd of August for the best clean, moderately-sized swell. The rest, you’ll be waiting for a gap in the wind.
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.
