The Lowdown
Alright, let’s break it down. Manly’s the only game in town, a sheltered point break that’s beginner-friendly. There’s a bit of a wait before we get into it.
We start on Friday, the 11th of September. The morning has a 6ft S swell, with a 10-second period, and a light SW wind blowing offshore. The combined energy is moderate at 672 – it’s got some juice. The water temp is about average for this time of year. It’s clean, but the swell direction is off the optimum, so it’s not perfect. The afternoon gets choppy with a cross-shore breeze, so the morning’s the one.
Saturday the 12th is the real gem. The morning is glassy – no wind at all. The swell is 4ft from the S, but the period jumps to 12 seconds, giving it real power (energy at 614). That’s a clean, chest-to-shoulder-high wave, and with the SSW wind blowing offshore, it’ll be a dream. This is the best day of the whole forecast. Crowds are likely, but it’s worth it.
Sunday the 13th goes downhill fast. The swell drops under 3ft, and the wind comes onshore from the NNE and NE, getting stronger. It’s small, messy, and not worth your time.
Monday the 14th and Tuesday the 15th are flat. The swell is tiny, energy in the double digits (70 and 42 on Tuesday). The wind is all over the place. A solid gap of poor surf.
Then Wednesday the 16th of September. The morning brings a big one: 10ft of S swell, period at 9 seconds, and energy at 1319 – that’s strong. The wind is offshore from the S, so it’s clean. But 10ft at a sheltered point is heavy, expert territory. The afternoon drops to 7ft, still clean. This is a powerful, raw day.
Thursday the 17th and Friday the 18th are a mess. Wind onshore, swell small. Friday morning has a weirdly long period of 19 seconds from the S, but with only 2ft of height and onshore wind, it’s a tease.
The weekend of the 19th and 20th of September is a slow return. Saturday the 19th is tiny and clean. Sunday the 20th has a bit more: 4ft from the S, with a nice cross-offshore wind, clean. Energy at 438. It’s marginal, but surfable.
The rest of the run into the end of September is poor. Small swell, onshore wind, weak energy. The two standouts are clear: Saturday morning the 12th for the glassy, clean groundswell, and Wednesday the 16th for the big, expert-only swell. Everything else is a hard pass.

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.
