The Lowdown
Alright, let’s talk about what’s coming up for Manly over the next couple of weeks.
It’s a slow start, but the wait is worth it. The first few days are pretty ordinary, with small, weak swells and funky winds. Sunday the 6th has some 4ft SSW swell, but it’s blown out by a 15 mph offshore wind, so it’s not going to be much fun. Monday morning the 7th looks a bit better – the swell drops to 5ft from the S, and the wind goes glassy, NNW at 3 mph. That’s a pretty window, but the swell energy is just moderate (304), and the period is a short 8 seconds, so it’ll be a bit lumpy and weak. Not a standout.
We then hit a solid run of poor conditions from Tuesday afternoon through to the end of the first week. The swell builds, but the wind is all over the shop, and the quality is just not there. The combined energy gets up to moderate (969) and even strong (1079) by Wednesday, but it’s messy.
Now, here’s where it gets interesting. The real standout is Friday morning, the 11th of September. We’ve got a solid 10ft swell from the S, with a groundswell period of 10 seconds, and the wind is offshore at 6 mph from the WSW. That’s clean, powerful surf. The combined energy is a massive 2814 – that’s strong wave energy, and it’s going to be a ripper for experienced surfers. This is the pick of the first week. The swell is over 8ft, so it’s for experts only. Manly is a point break, so it’ll handle that size well, but expect it to be a bit of a handful.
The next couple of days after that fade a bit, but we get another cracker on the 18th of September. Friday afternoon, the 18th, is the absolute highlight of the whole forecast. We’re looking at a 16ft swell from the S, with a very long period of 13 seconds. That’s a proper groundswell. The wind is offshore, light at 6 mph from the WNW, and the combined energy is a staggering 15179 – that’s exceptional power. This is world-class, expert-only surf. The swell direction is SSE, which is a good match for the optimum SE direction for Manly. This is the one to circle on the calendar. Saturday morning the 19th will still have a solid 8ft SSE swell with a 12-second period and light offshore wind, so that’ll be a good follow-up session for experienced surfers, but the 18th is the day.
The water temperature is sitting at 64°, which is about average for this time of year, so no surprises there.
So, to sum it up: the first week is mostly a write-off, but Friday the 11th is a solid, expert-level day. The absolute standout is Friday the 18th of September – that’s the one you wait for. Expect epic, powerful waves, but it’s for experts only. If you’re a beginner, give this whole period a miss.

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.
