The Lowdown
G’day, Rusty here. Look, straight up, I’ve only got one break on the menu for this 16-day stretch, and that’s Middleton Point. It’s a consistent point break that’s a solid beginner wave, so don't go expecting any heavy barrels. The water temp is sitting at a pretty average 58°, nothing unusual for this time of year.
The next few days are a bit of a slow grind. Tuesday morning is small at 4 ft from the SSW with a very long 17-second groundswell and a cross-off breeze, but the energy is weak (914) and the call is marginal. The afternoon cleans up nicely with a gentle offshore from the NNW and 3 ft waves, making for a good, clean session for the learners. Wednesday and Thursday stay small, around 3 ft to 5 ft, but the winds are cross-off or cross, keeping things clean if a little weak.
Now, Friday the 21st we see a jump in size – 6 ft in the morning from the SW, and the energy is really starting to hum at 2424. The wind is light cross, so expect some small ripples but still surfable. Saturday the 22nd is the real standout for the first week. We’ve got 8 ft to 8 ft SSW swell with a proper 16-second period and huge energy readings of 2881 and 3125. Winds are light, cross for the morning and cross-on by the arvo – so it’s clean enough but getting a bit bumpy later. This is still within beginner range though, so that’s good news. For a cleaner option, Sunday the 23rd morning is the pick: 6 ft SSW, 14-second period, light offshore wind from the north, and a solid energy of 2299. That’s clean, punchy, and should be a lot of fun. Expect crowds though – this spot is “sometimes” busy.
The middle of the week from Monday the 24th to Tuesday the 25th gets a bit messy. Monday is 5 ft and clean but the energy drops to 978. Tuesday turns onshore and choppy with 7 ft from the SW, which is honestly more interesting for kite surfing than paddle surfing. Wednesday the 26th afternoon brings a bit of salvation: 7 ft SSW with a gentle offshore from the NNW and clean conditions – that’s a good session.
Now, pushing into the second week, things get more interesting but less certain. Thursday the 27th through Saturday the 29th sees solid to big swell. Thursday morning has 8 ft from the SW with 13 seconds and a big energy of 2309 – that’s expert territory in the morning, getting into the 8 ft range later. Friday the 28th is just plain massive: 13 ft from the SW with a 13-second period and ridiculous energy readings of 5088 and 5657. That’s way too big for this break, even for a beginner spot – save this one for the big wave chargers only. Saturday the 29th morning still has 10 ft, so same deal.
We tail off into September with cleaner but smaller surf. Sunday the 30th has fresh cross-off winds and 5 ft, but a storm risk in the arvo kills the vibe. Monday the 1st of September morning is 5 ft with clean cross-off winds from the WNW – decent. The real little gem is Wednesday the 2nd of September morning: 3 ft from the SW, 16-second period, and glassy conditions. That’s clean, tiny, and perfect for a longboard.
Overall, the best on offer is Saturday the 22nd with that 8 ft SSW groundswell and light winds, but for cleaner conditions, Sunday the 23rd morning with the offshore is the one to chase. After that, the big stuff on the 28th is a spectacle but not for everyone.
Rusty.

Information about the Middleton Point Surf forecast
The above surf forecast table for Middleton Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Middleton Point can be found by selecting the local surf guide option on the grey menu. Our Middleton Point 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 Point) 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 Point 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.
