The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the Manly stretch over the next couple of weeks.
First up, the water temp is sitting about average for this time of year, so nothing to worry about there. The swell pattern is a bit of a mixed bag, with a few windows that are worth paddling out for, but plenty of flat spells in between.
The opening session on Thursday the 10th is a bit of a write-off – 8ft of south swell, but the wind is messy and it’s more of a struggle than a session. We’ve got a gap of poor surf through until the next worthwhile moment.
The real standout is Saturday the 12th morning. Manly has a clean 4ft south swell, with a 12-second period pushing some moderate energy (612). The wind is completely glassy – dead calm. That’s about as good as it gets for a clean, lined-up wave. The swell direction is slightly off the optimum, but when it’s glassy like that, you forgive a lot. Keep in mind it’s a point break that’s fairly consistent, and crowds are often around, so get out early.
After that, we hit a flat spell. From Sunday the 13th through to Friday the 18th, it’s mostly small, weak, and onshore. Not worth writing home about. The energy drops right off, with numbers like 261 and 88. You’ll be waiting.
Then, on Saturday the 19th morning, a big pulse arrives – 12ft of south swell, with a massive 2229 combined energy. That is a serious amount of water moving around. But it’s a bit of a tricky one – the period is 10 seconds, and the wind is only light cross-onshore, so it could be a bit lumpy. This is for experienced surfers only; that size and energy will be a handful, especially for a beach break. It’s not ideal for a paddle, but if you’re a strong swimmer and know the spot, it might be a wild one.
The following week has a couple of moments. Thursday the 24th morning sees a 7ft SSE swell with glassy conditions – very clean, but the period is a short 8 seconds, so it’ll be a bit crumbly and less punchy. The energy is still moderate (772). It’s a decent option, but not as clean as the 12th.
Friday the 25th morning rounds things out with a 4ft south swell, 10-second period, and clean cross-off wind. It’s a good, solid end to the forecast window, but nothing to write home about.
Bottom line: The 12th morning is the pick of the bunch – glassy and clean. The 19th is for the brave only. The rest is a lot of waiting around.
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.
