The Lowdown
Alright, cobber, Rusty here. Let’s have a look at what the next couple of weeks are shaping up to be for Manly.
We’re in for a bit of a slow burner this period. The start of the run is pretty messy, and we’re going to have to work for anything decent. There’s a big gap of poor days before we finally see something worth getting wet for, and then it gets a bit ordinary again. But hang in there, because there is one solid window that stands out above the rest.
The first real sniff of action is Thursday morning, the 10th. We’ve got a 8.2ft south swell rolling in with a 9-second period, and it’s carrying moderate energy (1140). The wind is offshore from the SSW, setting up clean conditions. Manly is a point break that’s fairly consistent, but the south swell direction is off its optimum, so expect it to be a bit more closed out than usual. Still, it’s the best of the early week, with that clean, offshore feel. Later that afternoon, the wind swings more cross-off and the quality drops off, so the morning is definitely the call.
Friday the 11th drops off a touch to a 6.2ft south swell, but the wind turns cross-off and it’s still clean enough. It’s going to be a bit weaker, with moderate energy (729). Saturday morning looks fun though, with the swell dropping to 3.9ft but the period stretching out to 12 seconds, which is a proper groundswell. The wind is glassy, WSW, and the energy is moderate (612). That’s a good-looking session for a point break, with clean lines. The afternoon turns onshore, so get in early.
Then from Saturday afternoon through the rest of the second week, things go pretty flat and windblown. We’ve got a stretch from the 12th afternoon all the way through to the 18th morning that’s not worth a second glance. Onshore northerly winds, tiny swell, and just a whole lot of nothing. It’s a proper lull. The water temp is around 64° and that’s just about normal for this time of year, so we’re not dealing with any crazy warm or cold water.
Now, the one standout. Get this in your calendar for Friday the 18th, in the afternoon. The winds go light offshore from the southwest, and that south swell jumps back up to 8.2ft with a 7-second period. It’s a bit short-period, so it’s going to be a bit on the punchy side, but it’s clean, the energy is moderate (648), and after all those flat days, it’s going to feel like a proper event. This is the best on offer for sure.
After that, Saturday the 19th brings a bigger pulse, 9.8ft from the SSE with a long 11-second period, and it’s got strong energy (1964). But the wind is a cross-off from the SSE, and with that size and direction, Manly is going to be handling a lot of water. The rating suggests it’s not going to be epic, and could be messy with questionable tides. It’s still one of the biggest swells of the period, but I’d be weary of it being too much of a good thing.
Beyond that, we’re back into the small, onshore mush through to the 24th. Nothing else worth paddling out for in this stretch.
The real takeaway here is Thursday morning (10th) for a clean, smaller session, and especially Friday afternoon (18th) – that’s the one to circle. The weekend after that is big but potentially messy. Other than that, it’s a waiting game.
Stay stoked.

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.
