The Lowdown

Alright folks, Rusty here. Let’s have a good look at what’s coming our way at Manly. This is a sheltered little point break that works best on a southerly swell, and we’ve got a pulse of that coming through, so there’s some hope, but a lot of the window is a write-off.

The first real standout is Thursday morning, September 17th. This is the best we’re going to see from this whole run. We’ve got a solid 10 ft south swell rolling in, with a clean 10-second period. The wind is blowing offshore from the SSW at 12 mph, so the faces are going to be nice and clean for the experienced surfers. The combined wave energy is pumping (3249), making this the clear pick.

While that Thursday is the main event, Friday morning, September 18th offers a nice little change of pace. The swell has dropped to 5 ft from the south, but the wind is absolute glass – NNW at only 3 mph. For a sheltered point like Manly, that’s about as good as it gets for a smaller, more user-friendly session. Don’t expect much power, but it’ll be pretty.

Now, the bad news. The water temp is sitting at 64°, which is about normal for this time of year, nothing to write home about. After that Friday morning glass-off, it gets grim. The swell drops off hard, and even when it picks back up around Tuesday the 22nd, the period drops to 7 seconds and the consistency turns into a choppy, onshore mess. From Saturday the 19th right through to the end of the month, nearly every session is marked by poor conditions with onshore winds or cross-shore chop. You will see a lot of “poor surf conditions” in the diary.

There is a faint flicker on Thursday morning, October 1st – a 4 ft south-east swell with a bit of a cross-off wind and a 9-second period (285 energy). It’s surfable, but ordinary. Nothing more. Honestly, this 16-day run is a one-hit wonder with that Thursday the 17th. Everything else is a long gap of flat or messy days. If you’re a beginner, Friday morning’s glassy 5 ft might be doable, but anything above that on Thursday is expert territory.

Stay patient out there.

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.
