The Lowdown
Alright, surfers, let’s get into it. Middleton Point is the only spot worth talking about for the next 16 days, and it’s a bit of a mixed bag. The water is right around 57°F, which is average for this time of year, so nothing freaky there.
We kick off August 20th with small, clean surf. Thursday morning you’re looking at 3ft of SSW swell, with a very long period of 16 seconds. The energy is weak (658), but a light offshore breeze is keeping it glassy. A long-period groundswell like this is best at this point break, as it might be too straight for a beach. Thursday afternoon bumps up to 5ft, still clean and cross-off.
Friday the 21st sees a jump in size to 7ft, with moderate energy (2690) and a 14-second period. The wind is cross-shore, so not perfect, but it’s rideable. Saturday the 22nd peaks at 8ft from the SSW, with strong energy (2891), but the wind is cross-shore and then cross-on, so it’s a bit lumpy. This size is getting into expert territory.
Now, the standout window is Sunday morning, August 23rd. We’ve got clean 7ft SSW swell, 14-second period, and a light offshore breeze from the NNE. That’s your best bet for the whole run – good power, clean faces, and the point will be handling it well. This is a proper good session for experienced surfers. Sunday afternoon stays clean but drops to 5ft.
Monday the 24th is still clean in the morning with 5ft, but the wind shifts and the energy drops. Then we hit a rough patch. Tuesday the 25th is blown out with onshore winds and rain. Wednesday the 26th cleans up again with glassy conditions in the afternoon but smaller at 5ft, and the period drops to 12 seconds, so less grunt.
Thursday the 27th brings another solid morning with 6ft clean and offshore from the NNW, and that afternoon is also clean with a 6ft SW swell. This is another strong, clean option. Friday the 28th has a nice 8ft SW swell with a 16-second period, and the wind is cross-off, but the energy is very strong (3425). The wind picks up to 15 mph, so it’s clean but a bit windy. That’s getting big and powerful again.
After that, it tails off. The last week of August and into early September has smaller, cleaner surf, but nothing that really stands out. The 30th sees a tiny 2ft swell with a very long 21-second period, but the energy is weak and the offshore wind is howling at 25 mph, so it’s a write-off. The first week of September is mostly small, under 4ft, and often cross-on, so it’s a flat spell. The last day, September 4th, afternoon brings a 4ft SSW swell with an 18-second period, which is promising but it’s a long way out.
So the bottom line: Sunday the 23rd and Thursday the 27th are your true standouts. Get on them while the wind is offshore and the swell has some size and power. The rest is a lot of waiting around.

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.
