The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way for Manly.
Right off the bat, there's a bit of a quiet spell to start. The first genuine action we see is a pulse on Tuesday the 11th afternoon, with a solid 6ft south swell. The energy is moderate (801) and it’s got a proper 11-second period on it, which is groundswell – the kind with some punch. It’s clean, with a light WNW breeze. That Tuesday afternoon session is your first real standout, but it’s a short-lived peak before things turn ordinary.
Wednesday and Thursday are average, with small 3-4ft S swells. Thursday morning (the 13th) is the best of that bunch with a clean offshore SW breeze, but it’s weak and won’t get the heart racing. Friday morning (the 14th) is the same story – clean but small.
Then we hit a rough patch. From Friday the 14th afternoon all the way through to the morning of Thursday the 20th, it’s pretty much all poor conditions. Strong south-easterlies and onshore junk keep the waves messy and unappealing. Expect a long, flat run for a good week.
Now, the light at the end of the tunnel. Look at Sunday the 23rd morning. That’s the best bet of the whole outlook. A 6ft NE swell, with a 10-second period, slams into the coast. The combined energy is over 1283 – that's strong. And the wind? A clean offshore SSW breeze. This one is for the crew who get up early. Manly is a point break, so this groundswell from the NE should line up nicely. It’s going to be a beauty.
After that, Monday the 24th is clean but smaller, and then Tuesday the 25th morning gets a bit hefty with a 10ft south swell. That’s expert territory only, and the energy is through the roof (2111), so it’ll be raw power. Not for the faint-hearted.
Keep in mind, the water is running at 62°F right now, about 2°F colder than normal for this time of year, so a good 4/3 is your friend. Manly can get crowded, and being "often" busy means you’ll have company on those clean days.
Overall, the week ahead is mostly a dud, but hold out for Sunday the 23rd – that’s the one to circle on the calendar.
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.
