The Lowdown
Alright, let’s get to it. The next couple of weeks are a bit of a mixed bag, so let’s break it down.
The first few days are going to be a write-off, I’m not gonna lie to you. We’ve got some cross-onshore winds and messy, choppy conditions through the weekend and into Monday. The swell is small and weak, with combined energy around 87 to 232 – just not enough push to get you excited. Water temp is sitting at 62°F, which is a bit colder than normal for this time of year, so you’ll want the hood if you’re getting in.
We’ve got a real lull from now until Thursday the 13th. That’s a long stretch with nothing worthwhile. But hold on, because Thursday morning is where it starts to turn.
Manly (Sydney) – On Thursday the 13th, we finally see some life. A 7ft SSW swell rolls in with a period of 8 seconds. The wind is offshore from the SW at 12 mph, and it’s looking clean. The combined energy jumps right up to 953 – that’s a solid, moderate pulse. By the afternoon, the wind drops right out to a slight air from the SSE, and the swell holds at 7ft, but the period stretches to 11 seconds. This is the standout of the whole run. It’s going to be proper. The water is still a touch cold, but you won’t care.
Friday the 14th morning still has some juice – 5ft of S swell at 11 seconds, with a cross-offshore WSW wind. It’s good, but not quite as strong as Thursday. The afternoon gets a bit onshore from the east, so get your session in early.
After that, we drop back into mediocrity. The weekend and early next week are small, with wave heights around 3ft to 4ft, and the winds are mostly cross or onshore. It’s not going to be great. The swell energy is weak to moderate, and a lot of it is coming from the south with short periods – not ideal for this spot.
Looking further out, there’s a glimmer on Sunday the 23rd. The morning shows a 5ft ENE swell with an 11-second period, and it’s glassy with a light WSW wind. Combined energy is up at 593, and it could be a decent one. But it’s over a week away, so don’t book your flights just yet. The afternoon gets onshore again, so again, morning is the go.
So, to sum it up: Thursday the 13th is your day. Get on it. The rest is either flat, small, or messy. Keep an eye on that Sunday the 23rd forecast, but treat it as a promising maybe.

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.
