The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—this is a grim stretch for Manly. The first week and a half is basically a write-off, so don’t bother paddling out until we get into September. The water’s sitting at 63°F, about 1°F cooler than usual for this time of year, so nothing too wild, just a bit of a chill.
The first real chance of anything decent doesn’t show up until Tuesday, September 1st, in the morning. That’s the standout. The swell is a solid 13ft from the east-northeast, with a 10-second period, packing some serious energy (4464). That’s a lot of power, so this is strictly for experienced surfers—beginners, stay well clear. The wind is light and offshore from the west-southwest, keeping the waves clean. At Manly, this kind of east-northeast swell isn’t the optimum direction (that’s southeast), but with that size and clean conditions, it’ll still pump. Just be aware, with crowds listed as “often,” you’ll have company.
After that, Wednesday morning, September 2nd, offers a 7ft east swell, 10-second period, and moderate offshore wind from the south-southwest (932 energy). It’s good, but not as big or clean as Tuesday. Still, a solid option for experienced surfers.
Thursday morning, September 3rd, sees a 5ft east swell, 9-second period, with a gentle offshore breeze from the southwest (435 energy). This is more manageable for intermediate surfers, but nothing special.
Finally, Friday morning, September 4th, gives us a 5ft south swell, 8-second period, with light cross-offshore wind from the west-northwest (471 energy). It’s a small window of okay surf, but the direction’s not ideal for Manly.
The rest of the forecast is poor surf conditions, with a long gap from now until September 1st. The only tiny flicker of hope is a few mornings (like Sunday, August 23rd, and Monday, August 24th) with glassy conditions and small south swell, but the waves are so ordinary they’re barely worth mentioning. If you’re desperate, those mornings are your best bet for a session, but keep expectations low.
Stay patient, and mark your calendar for September 1st. That’s the one worth chasing.
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.
