The Lowdown
G’day, Rusty here. Let’s take a look at what’s shaping up for Manly over the next couple weeks. There’s some good stuff, but also a lot of waiting in between.
Water temp’s at 64°F, pretty much normal for this time of year, nothing wild.
Friday the 11th of September morning is the first real option. Clean 6ft southerly swell, 10-second period, with a light offshore breeze from the WSW at 6 mph. That’s a solid size, decent energy (660). The afternoon goes choppy with a cross-on wind, so hit it early.
Saturday the 12th of September morning is the gem. Absolutely glassy – dead calm – with a clean 4ft southerly groundswell and a nice 12-second period. Energy’s moderate (621). That’s going to be the cleanest, most fun surf of the whole forecast. Afternoon gets messy with onshore wind, so morning is the move.
Sunday the 13th and Monday the 14th are small and weak. Swell under 3ft, poor winds. Not worth it.
Tuesday the 15th is tiny – 1 to 2ft – very low energy. Flat.
Wednesday the 16th of September morning brings a big pulse: 12ft southerly swell, 10-second period, with a cross-off breeze from the SSW at 19 mph. Energy is massive (2289). This is for experts only. Too big for anyone else. The afternoon drops to 8ft, still heavy (1253). The wind keeps it clean, but the size is intimidating.
Thursday the 17th of September morning is a nice drop to 6ft, clean with a light cross-off. Energy good (727). A solid, manageable session. Afternoon goes cross-on again.
From Friday the 18th through Tuesday the 22nd of September, swell is mostly under 3ft with onshore or cross-onshore winds. Low energy. Wednesday the 23rd afternoon has 7ft but with a cross-on breeze – lumpy and marginal. Thursday the 24th morning has 5ft, still cross-on.
The last few days, Friday the 25th and Saturday the 26th, are small and weak. Nothing to get excited about.
Bottom line: Saturday the 12th of September morning is the absolute winner – glassy, 4ft south groundswell, long period, clean as a whistle. The big swell on Wednesday the 16th is for the brave. Everything else is a skip.
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.
