The Lowdown
G’day, Rusty here. Let’s talk about what’s shaping up for Manly over the next couple of weeks. It’s a slow start, but there’s a big one coming.
Right off the bat, Saturday the 18th and Sunday the 19th are pretty ordinary. Saturday morning shows a 4ft ESE swell, 6-second period, and a cross-off wind, but the energy is weak (197) and the surf is just poor. Not worth getting wet. Sunday morning jumps to 8ft from the ENE with an 11-second period, and the energy is strong (1387), but the wind is cross and conditions are only marginal. That afternoon cleans up nicely with a light cross-off breeze and a 7ft ENE swell, 10-second period, and the energy is still strong (1034). That’s the first real window – clean, good shape, and solid size. That Sunday afternoon is the standout for the near term.
Monday the 20th morning is still clean with a 6ft ENE swell, 11-second period (885 energy), and a light offshore wind. It’s good, but not as punchy as Sunday. Then things fade through the week. Tuesday through to the end of the month sees the swell drop and the wind swing around. There are a few clean moments, like Wednesday the 22nd afternoon with glassy 3ft ENE swell, and Thursday the 23rd morning with a light offshore and 3ft, but honestly, the energy is weak (177 and 96 respectively) and the waves are ordinary. There’s a long gap of nothing special here.
Now, hold onto your board. Friday the 31st of July morning is the real deal. A massive 15ft S swell, 13-second period, and the energy is absolutely pumping (10000). The wind is light and offshore, so it’ll be clean. That’s proper big-wave territory – over 8ft, so for experts only. The swell direction is due south, and Manly’s optimum is from the SE, so it’s a bit off-angle, but with that much energy and a clean offshore breeze, the point should fire. Expect long, powerful lines. The crowd might be a factor, but on a day like that, the lineup will be thin.
Saturday the 1st of August morning is still solid with a 10ft S swell, 11-second period, and clean cross-off wind (2341 energy). Also for experienced surfers. Sunday the 2nd of August morning brings another 13ft S swell, 11-second period, light cross-off, and massive energy (3202). That’s another expert-only day.
So, the standout is absolutely Friday the 31st of July morning – huge, clean, and powerful. Sunday the 19th afternoon is the best of the first week for intermediate paddlers. Water temperature is about average for this time of year, nothing unusual there.
Keep an eye on that last week of July and the first of August – it’s got some serious potential, but it’s a long way out, so not set in stone.
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.
