The Lowdown
Alright mates, grab a cuppa, let’s run through what’s happening at Middleton Beach. It’s a bit of a quiet start, but there’s some real firecracker days if you know where to look.
First up, September 1st kicks off the surf with 7ft to 8ft SSW groundswell, a solid 13 to 15 second period. That’s proper energy (combined swell energy around 2345 to 2378), but a moderate cross-off breeze is blowing, and the call is "marginal" with tricky tide conditions. Surfable, but not a stunner. The 2nd sees the swell bump to 10ft from the SSW, still cross-off, energy climbing to 3195 – a touch messier, still not the pick.
Now, Thursday the 3rd – this is a standout. Morning session brings a clean 12ft SSW swell, 15-second period, and for the first time the wind goes offshore from the WNW at 15 mph (25 km/h). The combined energy hits 5634 – that’s moderate-to-strong – and it’s saying “excellent” for experienced surfers. This is for the big-wave crew only.
Friday the 4th gets massive – 18ft of SSW groundswell, period around 15 to 16 seconds, but the wind is a messy cross-off, and the combined energy blows up to a whopping 12923 then 14029. That’s a major ocean event for experts only, and the wind takes the shine off.
There’s a quick window early on Saturday the 5th with 8ft SW swell, but a strong northwest breeze at 25 mph makes it poor. That afternoon, it’s 16ft and near gale winds – a hard pass. Sunday the 6th and Monday the 7th still hold 10ft to 16ft SSW swell, but cross-off winds keep it from being clean.
Then Tuesday the 8th – absolute magic. A 13ft SSW groundswell, 16-second period, and the wind is dead calm – completely glassy. Combined energy sits at 7776, and the forecast says “excellent” for the experienced. This is the premium session of the whole outlook.
After that, the second week settles. Wednesday the 9th has a 8ft swell with a 20-second period – super long period groundswell, tricky at a beach break but with clean cross-off winds, it might wrap. Thursday the 10th offers another offshore window in the afternoon with 10ft SW swell and moderate offshore breezes. After the 11th, the size drops gradually. By the 14th and 15th, we’re seeing 6ft to 8ft SSW swell with lighter breezes and clean conditions – good for a relaxed paddle-out.
The best of the best? Thursday the 3rd and Tuesday the 8th for the experienced. Water temp is running about average for the season, nothing unusual.

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.
