The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for Manly over the next couple of weeks.

Frankly, it's a pretty grim stretch for the most part. We've got a solid 16-day window ahead, but the first good surf doesn't really show up until Sunday the 23rd, and even then it's nothing to write home about. There are long gaps of “poor surf conditions” with zero scores, so don't be in a rush.

The first real chance comes on Sunday morning, the 23rd of August. Manly will see a small southerly swell, around 5 ft, with a period of 9 seconds. The wind is glassy – that's a major positive, meaning the surface will be clean and smooth. Wave energy is moderate, sitting at 360. It's a beginner-friendly point break with a fairly consistent wave, but remember, it's sheltered from the south, so that swell direction isn't ideal for this spot. Still, if you're a learner, that glassy morning might be your best bet for a quiet, fun session.

The next standout, and honestly the best of the whole period, is Monday the 31st of August. The morning brings a long-period southerly groundswell at 2 ft with a period of 17 seconds. That's a very long period swell, which means waves with real shape and energy, but it can break a bit straight on a beach break. However, Manly is a point, so it should handle it well. The combined energy is high at 483, and with a light north breeze, the conditions will be clean. These are the best waves in the forecast, but the swell is small, so it won't be big.

The following Saturday, the 5th of September, has a fresh offshore wind from the west-southwest at 19 mph, combining with a 3 ft southerly swell at 12 seconds. That's a solid offshore wind, which will groom the face beautifully. The energy is strong at 325. The swell is small, but for a long-period groundswell with that wind, it could be a fast, clean little wave for the experienced crew.

To be honest, water temperature is around 63°, which is about 1° cooler than normal for this time of year – not a big deal, just a touch fresh.

For the rest of the two weeks, you're looking at onshore winds, cross-shore chop, and tiny windswell that just isn't worth the paddle. Surfable waves show up for a few mornings, but the quality is very ordinary. Don't hold your breath.

Rusty out.

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.
