The Lowdown
Alright, Rusty here. Let’s talk about what Manly’s got cooking over the next couple weeks.
We’re looking at a pretty slow start, with the first real chance of a wave showing up on Saturday morning, September 6th. That first morning is a bit of a teaser – clean lines with a 4 ft SSW swell, but the wind is a bit stiff out of the SW at 15 mph. It’s surfable, but nothing to write home about. The water temp is a normal 64° for this time of year, nothing unusual there.
Sunday morning, September 7th, is where it starts to get interesting. We’ve got a glassy morning, wind out of the WNW at just 3 mph, and a 5 ft S swell with an 8-second period. It’s clean, it’s rideable, and that glassy wind is a major plus. This is the best bet in the first week – a proper morning session.
Then the energy ramps up. Through the middle of the week, we’ve got a building swell from the SSE, but the wind gets messy. By Thursday, September 11th, the morning glass-off from the NW is gone, but we see a solid 8 ft S swell with a 10-second period and the combined energy is reading strong (1351). The wind is cross-off from the S at 12 mph, keeping it clean enough for experienced surfers. This is big and punchy, not for beginners.
Looking further out, the real standout sits on Thursday afternoon, September 17th. That’s when a long period groundswell from the S at 8 ft and a period of 12 seconds hits, with the combined energy very strong (2111). The wind is cross-off from the SSE at 15 mph. That’s a powerful, well-shaped wave. If you’re an expert, circle that date.
Between these highlights, there are gaps. Most afternoons get chewed up by onshore or cross-on winds. Don’t expect a good session every day. Tuesday, September 15th, sees strong S winds at 22 mph and a 8 ft swell – that setup is going to be choppy and tough, more of a kite-surfing day than a clean paddle session.
So, the call is simple: the best windows are Sunday morning the 7th for clean, fun waves, and the Thursday the 17th for the bigger, long-period groundswell. The rest? Pick your mornings and keep your expectations in check.
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.
