The Lowdown
Alright, this is Rusty.
Honestly, mate, the next 16 days look like a real mixed bag, and we’ve got a bit of a slow start to get through. The first real action that’s worth paddling out for shows up on the morning of Tuesday the 11th, but before that, it’s a flat, quiet stretch.
We kick things off on Tuesday the 11th with a morning session at Manly. Swell is a clean 4ft from the SSW at 7 seconds, so it’s a short-period, wind-affected swell. The wind is cross-offshore from the W at 12 mph, which should keep the surface tidy. The combined wave energy is moderate at 201. The water is sitting at 62°, which is a bit colder than average for this time of year, so don’t forget the booties. The morning gets a score of zero out of ten, but honestly, the wind is good and it’s the first wave of the window. The afternoon picks up a bit more energy: 6ft from the S at 11 seconds, with a light WNW breeze at 6 mph. That’s a better swell, with a longer period, and the energy jumps way up to 794. This is the standout of the first few days, with a score of 2 out of 10. It’s not going to be pumping, but it’s the best you’ll get.
Wednesday the 12th is a bit of a letdown. The morning offers 4ft from the S at 10 seconds, with a cross-off W wind at 9 mph. Clean, but ordinary. The afternoon sees the drop to 3ft from the S, but the wind swings to a clean offshore from the WSW at 12 mph. The energy is down to 216. It’s rideable, but nothing to write home about.
Thursday the 13th, the morning has a 4ft SSW swell with a gentle offshore SW wind at 9 mph. The energy is moderate at 361. The afternoon brings a bigger 6ft from the S at 8 seconds, but the wind switches to a messy cross-shore from the SE at 9 mph, creating a bit of chop. The energy is high at 708, but the quality drops.
Friday the 14th is a dud. The morning has 4ft from the S at 8 seconds with a light cross-off W wind, but the energy is weak at 208. The afternoon gets worse with a cross-shore SE wind at 9 mph and poor surf.
From Saturday the 15th all the way through to Monday the 24th of August, it’s a long, bleak stretch. The wind is constantly onshore, cross-shore, or just too strong. The swell is inconsistent, and the quality is poor. There are a few spikes in size, like Saturday the 15th with 6ft from the S, but the wind is 19 mph from the S, making it a messy, blown-out mess. The combined energy is moderate, but it’s not worth the paddle. This is a full week of bad conditions.
We finally get a glimmer of hope on Wednesday the 19th of August. The morning at Manly offers a 3ft swell from the ESE, but the period is a very long 12 seconds. This is a groundswell, and the energy is surprisingly high at 410. The wind is light from the SSE at 6 mph, keeping it clean. This is a score of 2 out of 10, and it’s the best we’ve seen in a week. It’s a small wave, but that long period and light wind will make for some clean, fun lines.
After that, it’s back to the doldrums. The rest of the forecast is a mix of onshore winds, poor conditions, and weak energy. The morning of Wednesday the 26th of August is the only other bright spot: a 4ft ENE swell, but the wind is glassy, calm at 0 mph. The energy is 208. The glassy conditions will make it look tempting, but it’s a tiny, ordinary wave.
Overall, the best bet is the Tuesday afternoon on the 11th with that 6ft S swell, and the Wednesday morning on the 19th with the long period groundswell. For everything else, save your energy.
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.
Manly is 6 km (4 miles) from Dee Why. If you plan a holiday in Sydney North Coast, look for hotels and other accommodation in Dee Why. Dee Why has rooms for a wide range of budgets as well as car hire and transport links.
