The Lowdown

Alright, Rusty here. Gotta be honest with ya, looking at the next 16 days for Manly and it’s a bit of a rough stretch. We’ve got a long, quiet gap to start, so don’t rush to grab your board just yet.

The first real chance for anything surfable rolls in on the morning of Tuesday, the 15th of September. We’re looking at a small, weak swell—about 3ft from the NE, but with a short, snappy period of 7 seconds and not much energy behind it (126). The good news is it’s clean with a light SW offshore breeze. It’s surfable, but very average. That afternoon it drops right off and turns messy, so that morning window is your only play that day.

Wednesday the 16th brings a sudden jump in size, but don’t get too excited. Strong southerly swell pushes in at 12ft with a moderate 10-second period. That’s a big, powerful wave (combined energy of 2426) and with a fresh cross-offshore breeze, it’s going to be a bumpy, tricky beast. That’s strictly for experienced surfers only; if you’re a beginner, sit this one out. The afternoon stays similar, just as big and a bit mushy. This setup honestly looks more interesting for kite surfing than for a clean paddle session.

Now, here’s the standout. Thursday morning, the 17th of September. It’s the one true gem of this entire forecast. The swell eases slightly to a still-chunky 10ft from the south, with that same 10-second period and a massive 3158 reading for combined energy. But the kicker is the wind—a light offshore from the SSW. That’s going to groom those faces and hold them up, delivering excellent conditions for experienced surfers. It’s not for the faint of heart, but if you’ve got the skills and the board for a solid South swell, this is your window. Expect some sets and some lulls with that period. The crowd factor is there, but on a thumping day like this, the pack usually thins out.

After that, it’s a slow fade. The rest of that week and into the next is a drawn-out run of weak, onshore, or messy conditions. Swell sizes drop below 5ft and the wind is mostly on it, leaving the surf pretty poor. From the 20th of September right through to the 26th, we’re looking at a dry spell. The energy completely bottoms out, with many days recording combined energy under 100 and waves below 3ft. It’s a classic flat patch for the area. A few small pulses try to show toward the end of September and the start of October, but they’re all onshore and junky. The 29th of September morning has a clean cross-offshore wind, but the swell is only 3ft and weak, so it’s a scratchy, small-wave session at best.

So, to sum it up: if you’re an expert, circle Thursday the 17th of September on your calendar. Everyone else, it’s a waiting game. The ocean will turn back on eventually, but for now, it’s pretty grim.

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.
