The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer down at Manly.
Right off the bat, the first day of the period, Wednesday the 9th, isn't a total washout, but it’s definitely not one to get excited about. We’re looking at a clean, manageable 3ft southerly swell, but the wind is a moderate offshore from the SSW. It’s surfable, but the conditions are just ordinary. The water temp is sitting at 64°, which is pretty much bang on average for this time of year, so that’s normal.
The real action, the standout of the whole 16-day window, is going to be Thursday the 10th. The morning is the pick. We’ve got a solid 8ft southerly swell rolling in with a 9-second period, and the wind is a moderate offshore from the SSW. The combined energy is pumping at a solid moderate 1027. This is a proper wave, and it’s going to be clean. It’s a bit of a step up in size though, so this one is for the experienced crew. Later in the afternoon, the swell drops a touch to 7ft and the wind goes cross-off, but it’s still a good session.
Friday morning the 11th is still a fun one. The swell is 6ft from the south with a 10-second period, under a light offshore breeze from the SW. The energy is still solid at 637. After that, things start to get tricky. Friday afternoon the wind turns cross-shore, and the quality drops.
Now, here’s a little gem that’s worth noting. Saturday morning the 12th is looking glassy. The wind is a whisper from the NNW, just 3 mph, and it’s glass. The swell is a smaller 4ft but it’s a long-period groundswell from the south, clocking in at 12 seconds. That’s a classic point-break wave. Manly is a point, so that long period will wrap in beautifully. The energy is still a moderate 608. This is a sleeper hit for the intermediate crew.
After Saturday, the bottom falls out. From Sunday the 13th all the way through to the end of the period, it’s a grim run. The swell drops to knee-high or less, and the wind is either onshore or cross-on from the north or east. There’s a brief flicker on Monday the 21st of September with a 5ft southerly swell and a strong offshore, but the wind is 16 mph, which makes it a bit of a battle. That’s the only real pulse in the second week, and it’s not a standout.
Overall, the best on offer is clearly Thursday the 10th morning for the big, clean swell. For a more relaxed, glassy session, Saturday the 12th morning is your quiet champ. The rest of the time, you’re looking at a long stretch of small, bumpy, or blown-out conditions.
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.
