Table - best surf conditions forecast for Manly-South Steyne over the next 16 days.
G'day, Rusty here. Let’s be straight with you – for Manly-South Steyne, the next couple of weeks are looking pretty grim overall. There’s a big hole at the start where there’s nothing worth paddling out for. We’ve got a long stretch of days with hardly any swell or just plain ugly conditions. The water temp is bang on average for this time of year at 65°, so nothing to complain about there.
From now through to around the 18th of July, it’s a write-off. Tiny waves, messy winds, and most days the forecast is just “poor surf conditions.” A few afternoons get a puff of offshore wind, but the swell’s barely a ripple – you’re looking at 0.7ft to 2ft. Not worth waxing the board. Even Wednesday the 15th sees a jump to 8ft, but that’s with a fresh breeze from the SSW making it cross-off, and the period is short at 9 seconds. Combined energy is moderate at 990, but the conditions are poor. Thursday the 16th is similar – 7ft from the SSE but with a period of just 7 seconds, so it’s short and choppy. That one’s really only for experts, and even then it’s messy.
The one standout in this whole outlook, and it’s the only time I’d get excited, is Sunday the 19th of July in the morning. The swell comes up to 8ft from the east with an 11-second period, and combined energy is strong at 1426. But the real magic is the wind – glassy, with a WSW breeze at only 3 mph. That’s as clean as it gets. It’s a reef break here, so a longer-period groundswell like that should wrap in nicely. It’s inconsistent though, so don’t expect non-stop sets, but when they come, you’ll be on. The break is also sheltered from the swell, so it won’t be as big as open beaches. Still, this is the pick of the bunch by a long shot. The morning on Sunday is the only time I’d rate as “very good surf conditions.”
After that, it’s back to the doldrums. Monday the 20th onward is mostly tiny swell – 1.0ft to 5ft – with onshore or light cross-off winds. A few days like the 22nd and 23rd have surfable waves but very ordinary conditions – just nothing to get stoked about. The second week is flat and forgettable.
So, bottom line: if you’ve got a window, make it Sunday morning the 19th of July. Glassy, solid east swell, and you might have the place to yourself given the crowds are only “sometimes” there. Every other day, leave the board in the garage.
That’s all from me. Stay salty.
Rusty.
