The Lowdown
Alright, Rusty here. Let’s take a look at what’s shaping up at Middleton Beach. You’ll have to be patient, but when it fires, it’s a proper session.
The first good waves roll in on Monday, August 18th. We’ve got a solid SW groundswell pushing through – wave heights around 8 feet, with a long 16-second period. The combined energy is reading between 3000 and 3300, so there’s some real grunt behind it. The wind’s light offshore from the NW on Tuesday, keeping things clean and lined up. Middleton Beach is a very sheltered break, but the SW swell will work its way in. Tuesday, August 19th is the pick of that first week – morning surf with offshore winds and clean conditions. It’s a bit much for beginners at over 8 feet, but for anyone with experience, it’s game on.
Things only get bigger. Wednesday the 20th and Thursday the 21st of August see the swell pump up to 10 to 12 feet, still from the SW, with a 15 to 16-second period. Combined energy jumps over 4000, hitting 6000 – that’s serious power. Winds stay light and offshore or cross-off, so the face will be clean. This is expert territory now. At 12 feet, the paddle out is a mission and the drop is steep. Friday the 22nd and Saturday the 23rd keep that energy going with 12-foot SSW swell and gentle offshores – more big, clean sessions if you’ve got the skills.
Then the wheels fall off. From Sunday, August 24th, the swell drops to around 5 feet, and the wind cranks up from the W at 25-30 mph, turning it into a messy, poor surf scenario. That rough patch lasts through to the 27th, with onshore winds and chop. Not worth paddling out for. Wave energy drops under 1000 during this time.
After that lull, the big stuff returns for the experts. On Thursday, August 28th, the swell jumps back to 15 feet from the SSW. There’s a fresh offshore wind, but the period drops to 11 seconds, so it’s a bit lumpy. Still, it’s clean. The real standout is Friday, August 29th, in the morning. Wave height at 8 feet, period back up to a very long 17 seconds, and glassy, light winds from the SSW. The combined energy is 4376, and the water’s clean. That’s a classic groundswell setup. At a beach break like Middleton, a 17-second period can make waves break a bit straight, but with near-calm winds, there’ll be some proper walls to pull into. Mark that date on the calendar.
A few more days of messy cross-onshore winds follow, but by Sunday, August 31st, we’ve got a smaller, clean 4-foot SW swell with a 15 mph offshore from the NW – a nice way to round things out.
Water temp is about average for the time of year, nothing unusual. It’s a patchy forecast, but when it’s good, it’s very good around here.
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.
