The Lowdown
Alright, let’s get into it. For Manly, it’s a bit of a slow start. Tuesday and Wednesday this week are a write-off – messy onshore winds, poor quality, just not worth paddling out. The water temp is sitting around 63°, which is about normal for this time of year, no real surprises there.
The first real glimmer comes Thursday the 27th morning. We’ve got a clean 6ft swell from the south with a light cross-offshore breeze out of the SSE. The combined energy reads 654 (moderate), and it’s shaping up nicely for a point break like Manly. That Thursday morning is the pick of the first few days – clean, decent size, and the wind doing us a favour.
Friday the 28th morning is also worth a look. Similar story: 5ft from the SSE, period bumping up to 11 seconds, light WSW offshore wind, and the energy is solid at 635 (moderate). Clean conditions again. That’s your other standout early on.
The weekend gets a bit messier. Saturday the 29th has some size – 7ft from the south – but the wind is a moderate cross-off, and the energy is high at 866 (moderate). It’s clean in the morning, but the swell is getting punchy; if you’re not an expert, that 7ft might be a handful. Sunday the 30th drops off, small and only ordinary.
Then we hit a dry spell. From Monday the 31st right through to Tuesday the 8th of September, it’s mostly small, weak, or blown out. There’s a few clean moments, but the swell is tiny – under 3ft – and the energy is low. Not worth getting excited about.
But hold on. Thursday the 3rd of September morning throws up something interesting. A massive 20-second period swell from the south, 5ft, but the combined energy is enormous – 2015 (very strong). That’s a proper long-period groundswell. The wind is a gentle cross-shore, so there’s a bit of chop, but the potential is there. Thursday afternoon looks even better: 6ft, still 20 seconds, clean cross-off breeze, and energy at 2503 (very strong). This is the standout of the entire outlook. For Manly, a south swell that clean with that period? It’ll be lined up and powerful. Best for experienced surfers – that long period will make it suck hard and throw.
Friday the 4th still has some juice – 6ft from the south at 16 seconds, clean in the morning, but the energy is dropping. After that, it fades into smaller, wind-affected surf through to the end of the outlook.
So, to sum it up: Thursday the 27th morning and Friday the 28th morning are your early winners. The real gem is Thursday the 3rd of September afternoon – that’s the one to circle on the calendar. Everything else in between is a lot of waiting.

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.
