The Lowdown

Alright, Rusty here. Let’s take a good, hard look at what Manly’s got cooking for us over the next couple of weeks.

Right off the bat, it’s a quiet start. Friday the 21st and Saturday the 22nd of August are basically a write-off for any decent paddle. Tiny, weak slop with onshore or no wind, and the combined energy is struggling to get past 54 (weak). You’re better off doing something else.

Sunday the 23rd of August morning is where we finally see a flicker of life. The combined energy jumps to 262 (moderate), with a 4ft south swell at 10 seconds. The wind goes glassy—a dead calm—so it’ll look clean. But that swell is pretty straight, and the scores are marginal. It’s surfable, but don’t expect a classic.

The real standout in this whole 16-day window is Thursday, the 27th of August – morning session at Manly. This is the day. We’ve got a solid 6ft south swell rolling in, with a period of 11 seconds, giving the combined energy a thumping 931 (strong). The wind is a gentle offshore from the southwest, meaning clean, lined-up waves. The optimum swell direction for Manly is SE, and this is a south swell, so it’s a good match, wrapping into the point nicely. This is the best on offer, no question. It’s still manageable for intermediate surfers, but it’s pushing the size for beginners.

Looking further ahead, the week of the 28th onwards gets messy. Friday the 28th has some clean moments with a 4ft swell and offshore wind, but the energy is dialed back. Then Saturday the 29th and Sunday the 30th are blown out by strong southerly winds, with the 30th seeing a massive 10ft cross-shore mess (combined energy 1152). That’s expert-only territory, and with the wind, it’ll be a washing machine. Probably better kite surfing that day.

A few pockets of clean conditions pop up on the 1st and 2nd of September, with 4ft and 3ft swells and an offshore breeze, but they are ordinary and lack punch. The water temperature is about average for this time of year.

So, bottom line: the first week is a slow grind, but Thursday morning, the 27th of August is your golden ticket. Set the alarm.

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.
