The Lowdown
Alright, Rusty here. Let's have a look at what Manly's got cooking for us over the next couple of weeks.
First up, the water temp is sitting at a pretty standard 64°, right where it should be for this time of year, so no shocks there.
The good news kicks off straight away. We've got a solid run from Thursday morning the 10th right through the weekend. Thursday morning is the real standout. A solid 8ft S swell, clean with a light offshore wind, and the energy is pumping hard at 1080 – that's a lot of power. The period is 9 seconds, so it's a bit on the shorter side, but with that wind and size, Manly's point will be running proper lines. Thursday arvo the wind swings cross-off, still clean, but that's more of a bonus session if you're keen.
Friday morning the 11th is another beauty, with 6ft S swell and a light SSW offshore. It's a touch smaller, but still very clean, with energy at 660. Friday arvo gets a bit messy with a cross-shore wind, so hit it early.
Saturday the 12th is a glassy gem. The swell drops to 4ft, but it's got a lovely 12-second period – that's real groundswell quality. The wind is dead calm in the morning, glassy as a mirror. The energy is still decent at 614. This is a classic dawny for the longboard or a mid-length, just you and the ocean. Saturday arvo gets a bit onshore and choppy, so morning is the call.
Sunday the 13th drops right off to under 3ft and the wind goes onshore, so we'll call that a rest day.
We then hit a long, flat spell. From Sunday arvo the 13th all the way through to Tuesday the 15th, it's tiny, onshore, and not worth paddling out for. Wednesday the 16th sees a pulse of 6ft S swell, but the wind is a cross-shore and the whole thing looks marginal. Not a recommended session.
The real story, and what could be the best period overall, is the following weekend. On Saturday the 19th of September, a big pulse is due. The morning shows a solid 12ft S swell with an enormous combined energy of 2576, but the wind is a light onshore. That's a lot of water moving, and if it's a beach break, it'll be a washing machine. But for a point break like Manly, this could be a big, powerful, exciting day for experts only. Anything over 8ft is just for those who know what they're doing. Sunday the 20th cleans right up. A 7ft S swell with a 11-second period and a clean offshore cross-off wind in the morning – energy at 1045. That's the true standout of the second week: powerful, clean, and quality.
After that, Monday the 21st drops off and gets onshore, so the window closes again. There's a flash in the pan on Friday the 25th with an 8ft SSW swell, but with a period of only 7 seconds, it'll be a bit jumbled.
Overall, the pick of the fortnight is easy: Thursday morning the 10th for the immediate, reliable power session, and Sunday morning the 20th for a promise of clean, powerful groundswell a week and a half out. Don't sleep on the glassy Saturday morning the 12th either. For the rest, you've got plenty of flat spells to get your other chores done.
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.
