The Lowdown
Alright, let’s take a look at what Manly’s got cookin’ for the next couple weeks.
Honestly, the first week and a half is pretty dead. From Monday the 17th through to Saturday the 29th of August, there’s hardly a ripple worth paddling for. The swell is tiny, weak, and just messy – combined wave energy barely hits triple digits most days. Winds are all over the place, mainly cross or onshore, and even when it goes glassy or offshore, the waves are under 3 feet and just don’t have any juice. You’re better off stayin’ home.
Water temp is 62°, which is a bit colder than usual for this time of year, so grab a thick suit.
Now, Saturday the 29th things start to stir. Swell hits 5 feet from the south, with combined energy at 486 – finally some moderate power. But winds are howlin’ offshore at around 22 mph, so it’ll be clean but pretty gnarly. That’s for the experienced crew only; a bit much for beginners.
Sunday the 30th of August is the big one. Manly’s point gets a solid 8 foot south swell, around 10-second periods, and combined energy jumps to 1070 – that’s strong. Winds are moderate offshore from the SSW at around 16 mph, keeping things clean. This is expert territory, especially with the swell pushing 8 feet by the afternoon. Only the brave and skilled should be out there.
But the real standout is Tuesday the 1st of September. The morning looks prime: 6 foot south groundswell, with a long period of 13 seconds, and light SSE winds at 6 mph giving you clean conditions. Combined energy is a powerful 1092. That’s proper, well-shaped energy. The long period will help the point at Manly hold together nicely. Expect good surf if you’re comfortable in solid overhead conditions. The afternoon drops to 5 feet and winds turn a bit cross-on, so that morning session is the one to chase.
Crowds at Manly can be thick on a good day, so get in there early.
First week’s a bust, but the last few days – especially that Tuesday morning – are well worth waiting for.

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