The Lowdown
Alright, let’s have a look at what’s on offer for Manly over the next couple of weeks.
Honestly, for a point break that’s usually a reliable little gem, this stretch looks pretty quiet for a while. We’ve got a real dry spell on our hands, with hardly any surf worth paddling out for. From now through most of the month, it’s a whole lot of small, weak, and messy. The water temp is sitting at 62°, which is a bit colder than normal for this time of year – you’ll want a decent steamer.
The only real window that gets my heart beating is right at the very end of the forecast period. Thursday the 27th of August sees a solid pulse of southerly groundswell pushing in. Early morning you’ve got 8 ft from the S, with a period of 10 seconds – that’s got some proper push behind it, combined wave energy reading 1445. It’s clean with a light offshore breeze, so Manly’s point should start shaping up nicely. That afternoon, the swell jumps to 10 ft from the S, period stretching to 13 seconds, and the combined energy rockets up to 5070. That’s a serious amount of juice. For a point break, that longer period will mean nice, lined-up sets – but 10 ft is big. This is expert territory. Beginners, stay on the sand for this one.
Friday the 28th of August still has good energy rolling in – 6 ft from the S, period 11 seconds, energy at 812 – but the wind swings around a bit more and there’s light rain around. It’s still surfable, but that Thursday morning window is the clear standout. That’s the one to circle on the calendar.
Other than that, it’s a long, flat wait. There’s a few mornings with glassy conditions and tiny, weak swell, but nothing that’ll get you out of bed.
So, save your energy, keep an eye on that Thursday the 27th. Could be a cracker if the forecast holds.

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.
