The Lowdown
Alright, mates, Rusty here. Let's get into it. The next couple of weeks are looking like a bit of a mixed bag. We've got a slow start, but there are a couple of windows where things should clean up and offer some proper waves. Keep an eye on the second week, there’s some potential there, but it’s a bit further out so we’ll have to see how it shapes up.
We're starting at Manly (Sydney) on Sunday the 9th. The water temp is 62.4°F, which is a bit colder than usual for this time of year. Nothing crazy, but you'll want the rubber. It's pretty gutless right now. A weak 3ft ENE swell with a 9-second period, and a cross-onshore wind has it all messy. Combined energy is weak (176). There's nothing happening, so don't even bother.
Monday the 10th gets a bit more interesting, but not in a good way. The swell jumps to 7.2ft, but it's coming with a strong cross-shore wind at 22-28 mph. It'll be a lumpy, chopped-up mess (862 energy). This is more of a kite-surfing day than a paddling day, to be honest. Not for the faint-hearted if you do go out.
Tuesday the 11th the wind drops right out, going light cross-offshore. The swell drops back to 2.6ft, but there's some clean conditions to be had, though the energy is still weak (145). It’s surfable, but very ordinary. Wednesday the 12th is similar, clean but small and weak. Not a lot of push.
Now, Thursday the 13th brings a bit of a shift. A clean, moderate offshore wind and a 4.3ft S swell with an 8-second period. It's still weak-ish energy (255), but it's a step in the right direction. By the afternoon, the swell picks up to 6.6ft and the energy jumps (729). Conditions are clean, but it’s getting a bit more serious.
Friday the 14th morning is where it starts to click. The wind is light, cross-offshore, and the swell is a solid 5.2ft from the south with a 10-second period. The energy is moderate (502) and it's looking like good surf. This is your first real standout. The period is a touch short of being a proper groundswell, but the clean conditions should make it fun. The afternoon turns onshore and gets choppy, so get your waves in the morning.
The weekend washes out a bit. Saturday the 15th has some S swell, but it's short-period and onshore. Sunday the 16th to Monday the 17th is poor. The swell is small, inconsistent, and the wind is cross-shore. Nothing to see here. This is a real lull for a few days.
Tuesday the 18th has a bit more size, 5.2ft, but the period is a short 7 seconds. It'll be a messy, wind-affected wave. Not worth your time. Wednesday the 19th is a bit of a write-off with onshore winds and rain.
Now, here’s where things get proper. Thursday the 20th. The forecast is for a gentle offshore wind, clean conditions, and a strong 6.6ft ENE swell with a 9-second period. The combined energy is strong (1069). This is your big standout for the whole period. It’s got size, it’s got power, and it’s going to be clean. The direction is a bit off from the optimum SE, and it might be a bit much for the beginners at 6.6ft, but for the crew that knows what they're doing, this is the day. The morning looks best before the wind swings around.
Friday the 21st gets ruined by a strong onshore wind. The swell is still there but it'll be blown out. Saturday the 22nd, however, is another cracker. Light offshore winds, clean conditions, and a solid 6.6ft ENE swell with a 10-second period. Strong energy (823). This is another standout, promising to be a really good day.
The rest of the window, from Sunday the 23rd onward, gets messier again. Strong winds, rain, and the swell drops off a bit. There might be some rideable stuff on Sunday morning, but it's not looking clean. The second week is definitely more of a waiting game on that Thursday and Saturday.
So, to sum it up: There's a lot of average to poor surf out there, but if you're keen, Thursday the 20th and Saturday the 22nd are the ones to circle on the calendar. They're looking like proper waves. The long-range nature of these means we can't be 100% sure, but the setup is right. Until next time, keep the stick salty.

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.
