The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at Middleton Beach for the next couple of weeks.
We’ve got a big pulse of swell coming in, but it’s not a simple one. The first real action is on Tuesday, the 11th of August. We’re talking a massive 20ft swell from the SSW with a very long period of 16 seconds, and a ton of energy behind it. The wind is a fresh cross-off, so the surface will be clean, but this is serious size. For anyone who isn’t an expert, this is a no-go zone – it’s way too big. The water temp is around 65°, which is a touch warmer than normal for this time of year.
The swell eases through Wednesday and into Thursday morning, the 13th. Thursday morning is the first real standout. The swell is still a chunky 13ft from the SSW, period hanging at 16 seconds, but the wind swings to a light offshore from the WNW. That’s the magic word: offshore. The surface will be glassy clean. This is for experienced surfers only, but the conditions are excellent.
The next true highlight pops up on Wednesday, the 19th of August. We get another 13ft SW groundswell, period 16 seconds, with a light offshore breeze in the morning. Then in the afternoon, the wind drops to glassy. Yes, glassy. This is a premium session if you’ve got the skill and the nerve for the size. It’s a big swell, so it’s expert territory, but the quality is undeniable.
The action starts to fade after that, with the swell dropping below 6ft by the 21st. The last little pulse to note is on the 25th, a Tuesday, with another 13ft SW swell, but the wind is a fresh cross-off, not quite as clean as the earlier windows.
So, the standout sessions are clear: Thursday morning the 13th, and the entire day of Wednesday the 19th. Both offer big, powerful groundswell with clean, offshore or glassy conditions. If you’re an experienced surfer, those are your windows. For everyone else, the first weekend (the 15th and 16th) has some smaller, more manageable 7ft+ swells, but the wind is a bit more mixed. It’s a solid stretch of surf, but respect the size.
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.
