The Lowdown
G’day, Rusty here, looking over the next couple of weeks at Manly. It’s a pretty grim start, I won’t lie. For the first week we’re stuck with tiny, weak dribble and a lot of onshore chop, so don’t bother paddling out until we get a proper pulse. The water temperature is sitting at 63°, which is a bit cooler than usual for this time of year, so you’ll want a good wetsuit.
The only real standout comes in the second week, and it’s a beauty. On Monday, September 7th, a solid SSE groundswell hits with 8 ft surf and a 10-second period. The combined energy reading is a meaty 1250, so there’s heaps of power in the water. The wind is cross-offshore from the WNW, keeping things clean. This is proper expert territory—8 ft is big, so only the experienced crew should be out. The swell direction is S/SE, and Manly likes it from the SE, so it’s a good match. Crowds are often here, so expect a lineup.
Sunday, September 6th afternoon sees a huge 15 ft southerly swell roll in, with a combined energy of 3574, but the wind is cross-shore and the wave quality is marginal. This is a kite surfer’s dream, not a paddle surfer’s. The rest of the week settles down with smaller, cleaner but ordinary waves, and the last few days from the 11th to the 14th offer only glassy mornings with weak, short-period ENE swell that’s barely surfable. The 13th of September morning has a bit of size—6 ft—but it’s a windswell with a 7-second period, and the onshore wind ruins it by afternoon.
So, bottom line: if you’re keen, aim for Monday, September 7th. It’s the only real gem in a long dry spell. The rest of the window is mostly forgettable.

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.
