The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ for Manly over the next couple weeks.
Right off the bat, don’t get your hopes up for the next few days. We’ve got a bit of a slow start. The run of surfable days kicks off this Sunday morning, August 23rd, with a small, clean little wave. Swell is 5 ft from the south, period hanging around 9 seconds – not a groundswell but it’s got enough push to get a longboard or a foamy groveling. The wind is glassy, which is a beautiful thing, and the water’s sittin’ at 62°, pretty much normal for this time of year. Combined energy is moderate at 374. It’s a mellow little session, nothing to write home about, but for a beginner-friendly point break like Manly, it’ll be fun if you’re just wanting a paddle.
Now, after that, it gets pretty grim for a good stretch. From Sunday afternoon all the way through Wednesday afternoon, the 26th, we’ve got onshore winds, rain, and choppy junk. Not worth your time.
Thursday morning, the 27th, though… that’s where things get interesting. Manly comes alive with a solid south swell pushing 6 ft, period around 9 seconds. It’s clean with glassy conditions, and the energy is strong, hitting 552. This is the standout of the whole forecast. For a point break, south swell works nicely, and with zero wind, you’re gonna get some clean, fun walls. Not too big for the average surfer, just a good, punchy size. Make sure you get out early before the afternoon onshores mess it up.
After that, we see a few other mornings that are clean – the 30th of August Sunday morning has 6 ft south swell and offshore wind – decent, but the conditions aren’t quite as perfect as Thursday. The 31st Monday morning is cross-onshore and bumpy despite the 6 ft swell, so skip it.
Then we hit a real dry spell from September 2nd onwards. The second week has a few clean-looking mornings with offshore winds, but the swell drops right off – under 3 ft, with combined energy down to three-digit weak numbers. There’s a brief moment on September 4th Friday morning with a tiny 1.0 ft south groundswell – period 13 seconds – but that is barely a ripple. Not worth paddling out for unless you’re desperate for a salt rinse.
So, the bottom line: the real highlight is Thursday morning, August 27th at Manly. That 6 ft south swell with glassy wind is your best window. After that, it’s a long stretch of small, weak surf. The break is fairly consistent but this is a pretty lean outlook, especially through the first week of September. Keep an eye on it – forecasts change, but right now, that Thursday is your golden ticket.
Rusty out.

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.
Manly is 6 km (4 miles) from Dee Why. If you plan a holiday in Sydney North Coast, look for hotels and other accommodation in Dee Why. Dee Why has rooms for a wide range of budgets as well as car hire and transport links.
