The Lowdown
Alright, Rusty here. Let’s chew the fat on what Manly’s got cooking.
Honestly, the next week and a half is a tough pill to swallow. There’s a proper gap before we even see anything rideable. Our first chance rolls in on Wednesday, August 19th, and it’s a weak little 2-foot wave from the ESE, with a period of 10 seconds. The water’s about 62°, which is a touch cooler than usual. The combined energy is weak (178), and the call is "surfable waves but very ordinary conditions." That’s as good as it gets for a long while.
After that, it’s a whole lot of nothing. We’re talking days of tiny, gutless swell and shifty winds. There’ll be a few glassy mornings, like on the 21st and the 24th, but with wave heights barely reaching 3 feet and energy readings in the 40-125 range, you’re basically staring at a flat spell.
Now, here’s the long shot that has my attention. Way out on Monday, August 31st, the afternoon looks like the real deal. It’s a speculative call, but the numbers are mouth-watering. We’re looking at a solid 11-12 foot S swell, with a period of 10 seconds – a proper groundswell with some muscle. The combined wave energy is a beastly 2125. The wind will be light and offshore from the SW, promising clean, groomed faces. This one’s for experienced hands only. That size on Manly’s point is a big, serious ocean.
For everything else, you’re hunting for clean but tiny waves. Some of those stronger cross-off wind days around the 25th and 26th might be better suited for a kite than a surfboard, with the swell over 4 feet but the quality just not there for a paddle surfer.
Bottom line: the next two weeks are mostly a dud. Keep your powder dry for that last Monday in August. It’s a gamble, but it’s the only ace in the deck.
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.
