The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on offer for us over the next couple of weeks.
Alright, so the outlook for Manly is a bit of a mixed bag. We’ve got a solid run of swell coming through, but the wind is going to be the main character in this story, and not always a friendly one. The water temp is sitting at 63°F, which is pretty much bang on average for this time of year, so no surprises there.
The first real chance to get a wet suit on is Friday the 17th. It’s small, with chest-high sets around 3 ft from the south, but the wind is a light cross-offshore. Combined energy is weak (113), so it’s not going to be a world-beater, but it’s clean and surfable for a beginner session. The afternoon drops off a bit.
Saturday the 18th is a write-off. The swell picks up a touch, but the cross-off wind is up to 12 mph and the conditions are just poor. Don’t bother.
Now, Sunday the 19th is where it gets interesting, but with a serious caveat. We’ve got a solid 7 ft east-northeast groundswell rolling in, with a long 11-second period. The combined energy is strong (1133). The problem is the cross-shore wind. It’s going to be lumpy and messy. This is a day for the experienced crew only, and even then, you’ll be working for it. The long period means it’ll be better if you can find a bank that holds, but it’s a beach break, so it might just close out.
Monday the 20th morning is the real standout. The swell drops to a very manageable 6 ft from the east-northeast, and the wind goes glassy from the west-northwest at just 3 mph. The combined energy is still solid (755). This is your session. Clean, offshore, and a decent size. It’s the best on offer, no question. The afternoon turns to crap with a strong onshore, so get it in the morning.
Tuesday the 21st is another promising morning. The swell is 5 ft from the east-northeast, and the wind is pure glass. Combined energy is moderate (496). It’s clean as a whistle. For a Tuesday morning, it could be a ripper. The afternoon again gets ruined by the onshore.
After that, the week from Wednesday the 22nd through to the 26th is a bit of a lull. Swell drops off, and the wind is mostly cross or cross-off, but the size is small. There are surfable waves, but nothing to get excited about. The energy is weak to moderate.
We then have a gap of a few days where it’s pretty ordinary until Wednesday the 29th. On the 29th, we get a big pulse of swell from the south, hitting 8 ft with a combined energy of 1649. That’s a lot of power. But the wind is a moderate cross-shore, and it’s going to be choppy. This is big, messy, and for experts only. The afternoon cleans up a bit with a cross-off, but it’s still a powerful 7 ft.
The end of the run on the 31st of July and into the 1st of August sees a lot of wind, with a strong cross-on shore and a big 8 ft swell. That’s not a paddle session; honestly, that setup looks more interesting for kite surfing than paddle surfing. The energy is massive (1260), but it’s blown out.
So, to wrap it up: the clear standout is Monday morning, the 20th of July. Get up early, it’ll be clean and fun. Tuesday morning the 21st is a close second, if you can sneak out. The rest is a mixed bag of size with wind issues, or clean but small. Keep an eye on the longer-range stuff for the 29th, but be prepared for a battle.
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.
