The Lowdown

Alright, Rusty here, let’s have a look at what’s cookin’ for Manly over the next couple of weeks.

Right off the bat, I gotta be straight with ya – the next week and a half is pretty grim. We’ve got a long stretch of nothin’ much worth paddling out for. There’s a bit of swell around, but the wind is all over the shop, and the wave quality is just poor. The first real glimmer of hope doesn’t show up until Wednesday, the 9th of September.

So, from now until then, it’s a whole lot of small, wind-affected slop. Most days, you’re looking at knee-to-waist high southerly swell around 3 ft, but with cross-shore or onshore breezes, it’s just messy. There’s a brief moment of glass on Monday morning, the 31st of August, with a 3 ft S swell and 8-second period, but the energy is weak (267) and the conditions are only “ordinary”. It’s a tough call, but if you’re desperate for a slide, that’s your best bet in the first week.

Now, the real standout is shaping up for Thursday, the 10th of September. That’s the one to circle on the calendar. We’re looking at a solid 8 ft southerly groundswell, with a long 11-second period. The combined energy is massive (1386), so there’s some serious power in the water. The big kicker here is the wind: glassy, dead calm, clean conditions for the morning. That’s a rare combo for Manly. For a point break, this long-period swell will wrap in nicely. Keep in mind, at 8 ft, this is expert territory only – it’s gonna be a heavy, powerful day. The water temp is about average for the time of year, so no surprises there.

The day before, on Wednesday the 9th, there’s a decent runner-up with a 6 ft southerly swell (energy 510) and clean offshore winds from the south in the morning. That’s a solid, fun day for intermediate surfers, but the Thursday morning glass is the real prize.

After that, Friday the 11th still has some juice with a 5 ft S swell and clean cross-offshore breeze in the morning, but the energy drops off a bit. Then it’s back to small, weak conditions as we head into the second week.

So, to sum it up: the next few days are a write-off. Hang tight, because Wednesday the 9th is a good session, and the Thursday morning, the 10th of September, is the absolute standout – a rare, glassy, powerful day at Manly. Don’t miss it if you’ve got the skills.

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.
