The Lowdown
Alright, let's break this down in feet and knots for you.
It’s a slow start, no doubt about it. The first week and a half is mostly flat and choppy, with a big gap of nothing special until we finally get a proper swell. The only real standout window is the last Friday and Saturday of the month, August 28th and 29th. That’s where the juice is.
Manly is a sheltered point, works best with a SE swell. The first moment worth paddling out might be that Wednesday morning, August 19th. It’s tiny, just 2 ft, but with glassy wind and a 10-second period, you’ll find clean little peelers for a log. The combined swell energy is weak though (173).
After that, we’re in the doldrums. A few clean mornings with offshore winds around the 25th and 26th, but the swell is only about 2 ft—rideable but nothing to write home about.
Now, the real deal. Friday, August 28th, the morning at Manly is looking prime. We’ve got a 6 ft swell from the NE with an 8-second period. The wind is glassy, and the combined energy jumps to a strong 807. Water temp is a bit colder than average at 62°, so bring a thicker suit. For a spot that’s often packed, this is the morning to get down early. It’s a bit much for beginners at 6 ft, but for anyone with a taste for a bit of power, it’s going to be clean and fun.
Saturday the 29th of August is also good in the morning. A smaller but still solid 5 ft from the NE, a 9-second period, and glassy again. Energy is moderate at 423. A great backup day.
After that, it’s back to small, onshore junk into September. So make your plans for that last weekend of August.

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.
