The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Manly over the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s a slow start. We’re looking at a stretch of pretty ordinary to poor surf for the first several days. Don’t get your hopes up for a quick paddle this week.

The first real chance of anything worth getting wet for shows up around Thursday, the 10th of September. We’ve got some moderate wave energy coming through (combined energy of all swells directed here at 1928) with a south swell at 10ft and a 10-second period. That’s a solid size for Manly, definitely not for beginners, and the cross-off wind keeps the face reasonably clean. It’s a bit of a beast though. By Thursday afternoon, that swell pushes up to 12ft (combined energy of all swells directed here at 2539), and the southerly wind stays cross-off. That’s expert territory, with some serious power behind it. The swell direction is straight out of the south, right in that optimum window.

Friday the 11th stays chunky. The morning sees an 8ft south swell (combined energy of all swells directed here at 1176) with a moderate cross-off breeze. Afternoon drops a bit to 7ft. It’s still messy and on the big side for most.

Now, for the real standout. Friday, the 18th of September – mark it. We’ve got a whopper of a groundswell arriving: a 13ft swell from the south-west, with a very long 13-second period. The combined energy of all swells directed here is through the roof at 5256. That’s a lot of water moving. The wind is offshore from the SW at 19 mph, so it’s going to be clean and hollow. This is only for the experienced crew. The long period will make the waves hold up proper, but at this size, it could be heavy and straight-breaking for a beach setup. The point will likely handle it much better. Keep an eye on that Saturday the 19th, too – the swell drops to a much friendlier 7ft from the SSE, the winds ease up, and the energy (combined energy of all swells directed here at 1038) is still pumping. That’s your best chance for the everyman surfer.

Water temp is sitting at 65°F, which is about spot on for early September.

Look, it’s a tricky forecast. The first week is a write-off for quality. We’ve got a gap of a few days with nothing worthwhile. But that second week, especially that Friday the 18th and Saturday the 19th, there’s some proper energy on the cards. It’s far out though, so don’t lock it in just yet. Keep checking back.

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.
