The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Middleton Beach over the next couple of weeks.
First up, we’re looking at a stretch that’s very sheltered, so it doesn’t take just any swell to get it going. We’ve got a big run of surf on the way, but it’s not all going to be clean and user-friendly. Water temps are sitting about average for this time of year, nothing weird going on there.
We kick things off on Friday, August 21st, with a solid 10ft SW swell rolling in. The period is a long 15 seconds, meaning it’s proper groundswell with some real punch. The morning session is clean with a slight offshore breeze, and the combined energy is a massive 4543 (moderate to strong). This is excellent surf, but with that size, it’s for experienced surfers only. The afternoon gets messy with an onshore breeze.
Saturday the 22nd sees the swell holding at 10ft from the SSW, still a good 16-second period. The cross-off wind keeps things reasonably tidy, but the energy is dropping (3875). Still a good session for the crew who know what they’re doing.
Sunday the 23rd drops off a bit, but Monday the 24th is a standout. The morning is glassy, with a light offshore breeze, and the swell is back up to 10ft from the SW at 14 seconds. The combined energy is 3391 (moderate). This is very good, clean surf. The afternoon stays glassy.
Tuesday the 25th has some messy morning conditions, but the afternoon brings a 8ft SW swell with 16-second period and a moderate offshore wind. The energy jumps back up to 3096 (moderate). That’s the call for Tuesday arvo.
Now, get ready for this. Wednesday the 26th of August is the big one. The morning delivers a 13ft SW swell with a 19-second period. That is a very long, powerful groundswell. Combined energy is 12590 (very strong). It’s only for the experts, and it’s clean with a gentle offshore breeze. This is the best on offer.
After that, the forecast gets shaky for a while. Late August and the start of September are mostly blown out or just messy, with strong winds and rain. There are some big swells, like the 12ft to 15ft sets on September 2nd, 3rd, and 5th, but the wind is often cross or onshore, making it rough.
The final standout is September 5th, a Saturday morning. We’re looking at a 15ft SSW swell, 18-second period, and an offshore wind. The energy is enormous at 11119 (very strong). That’s another one for the big-wave chargers only.
So to sum it up: the real standouts are the morning of Wednesday the 26th of August and the morning of Saturday the 5th of September. Both are big, powerful, and for experts only. Everything else is a bit of a mixed bag with wind and conditions.
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.
