The Lowdown
Alright, this is Rusty checkin’ in from the beach. Let’s have a look at the charts for Manly-North Steyne.
Right off the bat, it’s a pretty grim start with a long stretch of nothing. The first week is basically a write-off. From Tuesday 11th August right through to the 19th, it’s all small, weak, and messy. You’ll see a little 2ft bump on the 11th with a light W breeze, but the swell is coming from the wrong direction (ENE) and the energy is weak (78). It’s surfable only if you’re desperate. After that, it’s a dry spell of tiny, crummy waves and onshore junk until the end of the second week.
The real standout is Thursday 20th August. That’s the one you circle on the calendar. We get a proper jump in size with a 8ft E swell rolling in. The wind is a light S breeze, which is cross-offshore, keeping things clean. The energy hits 951 – that’s proper juice. This is solid, powerful groundswell with a 9-second period, and it’s pointing straight into the break. This is a day for experienced surfers only; at 8ft, it’s well into the expert zone. The water temp is sitting at 62°, which is a bit colder than normal for this time of year, so don’t forget a hood.
Friday 21st August is also a cracker, with a 7ft E swell and a glassy WSW offshore wind of just 3 mph. The energy is still high at 786. The waves will be clean and lined up, a touch smaller than Thursday but still a powerful wave. It’s a fantastic follow-up day.
Saturday 22nd August morning still has some decent 5ft E swell with light S cross-off winds, but the energy drops to 360. It’s still good, but the quality drops off in the afternoon when the wind swings onshore.
After that, the swell hangs around for a few more days in the 4ft to 5ft range, but the wind is mostly cross or onshore, so it’s going to be a bit of a battle. The 23rd through the 26th you’ll find some rideable waves, but nothing to write home about.
So, the long and short of it: suffer through the first week, then get ready for a proper thumping session on Thursday 20th and Friday 21st August. That’s the best on offer.
Rusty.
