The Lowdown
Alright, Rusty here again, this time in feet and miles.
First up, the next couple days look pretty average, but don’t walk away yet. A big, long-period groundswell from the south-southwest is lined up, and it’ll stick around. Early in the week (Tuesday into Wednesday) the wind is cross-off and cross, keeping things rough, and the swell is just way too big for Middleton Point. By Wednesday afternoon and Thursday, the swell is running 10ft to 12ft with a 16-second stretch – that’s expert-only, way too much push for a learner. The combined wave energy is pumping: 5472 and 5879 (moderate-strong). If you’re not a seasoned paddle surfer, this setup might be better for kiting.
Into Friday the 14th and Saturday the 15th, the swell drops to 8ft-10ft, still with that long period (15-16 seconds), but the wind turns light and variable, even offshore at times. The energy is still solid (3436 and 2813). It’s still big, but cleaner – Saturday the 15th morning with light east cross-off winds could be a window for strong surfers who know the break.
The real standout of this whole forecast lands on Monday 18th August. Middleton Point gets a 5ft SSW groundswell, but the period stretches out to 18 seconds – that’s proper long-range groundswell. Winds are light northeast and cross-off, keeping the face clean. Combined energy runs 1930 (moderate), and the report says excellent for experienced surfers. That’s the one to aim for. The break is a point, so that long period will wrap in nice and draw out the lines. Just remember, crowds are possible here when the quality’s up.
After that, the swell fades through the 19th and 20th, but Thursday the 20th afternoon has another good one: 4ft from the SSW, 17-second period, with light cross-off breeze and energy of 1009 (moderate). Water temp is around 57°, normal for the time of year.
The second week gets more mixed. There’s a shorter-period, sloppier pulse around the 23rd (12ft but only 9 seconds) that’ll be messy and onshore. Then Monday 24th and Tuesday 25th serve up clean 3ft to 6ft SSW groundswell with lighter winds and cross-off conditions. Tuesday 25th afternoon looks tidy: 6ft from the SW, 17-second period, light offshore breeze, energy 1868 – another one for experienced surfers wanting clean, long walls.
So the pick of the bunch: Monday 18th August, Middleton Point morning. Second shout goes to Tuesday 25th August afternoon. Both have good size, long period, clean wind, and moderate energy.
Signing off, 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.
