The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the cards for Manly over the next couple of weeks.

To be honest, it's a pretty grim start. There's a lot of nothing happening for a good stretch, and the whole first few days are a write-off. The first real sign of life doesn't even show up until the afternoon of Thursday, 3rd September, and even then it's tiny. We're looking at a 1 ft SSE swell with a period of 11 seconds, giving us a weak 92 combined energy. The wind is light offshore from the WSW, so it'll be clean, but there's just no power in the water. You'd be struggling to get a ride.

The real story, and the only standout in this entire outlook, is the swell that's due to arrive on Wednesday, 9th September. It's a long way off, so keep that in mind, but it's got some serious potential. A solid 8 ft Southerly swell with an 11-second period is forecast for the Wednesday morning, packing a massive 1174 combined energy. That's a lot of water moving around. The wind is a clean cross-off from the South, which is a massive positive. It'll be a powerful, clean groundswell. Because of the size, over 8 ft, and the power, this is for experienced surfers only. The 11-second period with a South swell is a good match for Manly's optimum direction of SE, meaning it should wrap in nicely. It's a shame the conditions are rated as "marginal" due to tide, so you'll want to pick your banks carefully. The water temperature is currently 63°, which is about average for this time of year.

After that big pulse, the swell drops away quickly. By Thursday, 10th September, it's still a solid 7 ft from the South, but the wind swings onshore from the NE, making it messy. The energy is still high at 1190, but it's not looking good for paddling.

The rest of the second week is a bit of a letdown. There are a few mornings with clean, offshore winds, like Friday, 11th September, but the swell is tiny and weak. By Sunday, 13th September, we're back to small, onshore slop. It's a real shame after that promising mid-week pulse.

So, to sum it up: the next week and a bit is flat and ugly. The one day to have circled in your calendar, with a big asterisk for the uncertainty of a long-range forecast, is the morning of Wednesday, 9th September. It's a big, clean, powerful Southerly swell at Manly, but it's strictly for the experienced crew.

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.
