The Lowdown
G'day, Rusty here. Let's have a look at what Manly's got lined up for us over the next couple of weeks.
Honestly, it's a pretty bleak start for a while. We've got a bit of a dry spell on our hands, with no proper surf recommendations on the cards for the first week and a half or so. It's not looking like much until late in the window.
That said, things do change, and there's one morning that stands out as the real keeper in this whole forecast.
The water temp is sitting at a cooler than usual 62°, about 2° below the norm for this time of year at Manly, so you'll want the steamer on.
The first real glimmer of hope doesn't come around until Wednesday morning, the 27th of August. Now, that's still a week and a half away, so take it with a grain of salt, but the charts are hinting at something special. We're looking at a solid 10ft swell rolling in from the south with a 10-second period. The combined swell energy is moderate to strong at 2280. This is a proper south groundswell, and for a point like Manly, that can be magic, as long as you're sitting in the right spot. Winds are forecast to be light and cross-offshore from the WSW, which should keep the surface glassy and clean. This is the standout, no question. It's a session for the experienced crew though, as 10ft is well into expert territory.
The afternoon of that same day, Thursday the 27th, the swell jumps up to 12ft but the period drops to 8 seconds and the wind swings onshore from the ESE, bringing a cross-chop. It'll be a bit of a mess, so the morning is the call.
Before that, you’ll find a few mornings with surfable but ordinary waves—like Friday the 21st and Saturday the 22nd with small 3ft to 4ft ENE swell and clean conditions—but nothing worth getting excited about. There's a gap of nearly two weeks from the start of the forecast where the picks are all zeroes.
So, to wrap it up: if you're keen on Manly, pencil in the morning of Thursday the 27th of August. That's your best bet by a long way. Everything else is just waiting for the next proper swell.
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.
