The Lowdown
G’day, Rusty here. Let’s chew the fat on Manly’s surf prospects for the next couple of weeks.
Water temp is hangin’ around 63°F, pretty much what you’d expect for late August – no weirdness there. The story goes like this: a pulse of decent swell mid-to-late week, then a long dry spell that stretches out for days.
Best wave of the run is Friday the 28th. Friday morning, Manly picks up a clean 6ft from the SSE with an 11-second interval – that’s real groundswell, plenty of grunt. Light offshore breeze from the SW keeps the surface glassy. Combined energy is a solid 758 (moderate to strong), and with that period, a point break like Manly will shape up nicely. It’s one for the experienced crew – too big for beginners. And yeah, crowds often roll through here.
Saturday the 29th morning is still worth a look: 4ft, SSE, 10 seconds, light offshore, energy at 562. Clean, fun, but a step down from Friday.
Sunday the 30th starts the fade. 3ft, light wind, but energy has dropped to 273 and the waves are ordinary. Monday the 31st has a glassy dawn with only 2ft and a very long 15-second period – that long gap between sets can make it feel smaller and fatter, though Manly’s point might handle it better than most.
Then it’s a desert. From Tuesday the 1st of September right through to the 10th, it’s tiny. Swell mostly under 3ft, energy readings in the double or low triple digits, and the wind shifts around cross or onshore more often than not. There’s a glassy moment on the morning of the 9th of September, but with just 3ft and energy at 136, you’re really just bobbing around.
So bottom line: Friday the 28th morning is your best bet, Saturday’s a decent backup, and then you’ve got a long stretch of flat to small conditions. Hang tight, it’ll come back around.
Rusty.

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.
