The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next few days are pretty grim for a paddle. The first real chance of a wave doesn’t show up until Monday morning the 20th, and even then it’s only a faint hope. There’s a long gap of nothing worthwhile before that.
Alright, let’s start with the first glimmer: Manly-South Steyne. Monday morning the 20th, it’s a tiny 2ft swell from the south with a period of 12 seconds. The wind is light and clean from the west-northwest, so it’s a cross-offshore breeze. The combined energy is weak (147). It’s surfable, but it’s ordinary. Don’t get your hopes up. This is a sheltered reef break that’s inconsistent, and it’s for advanced surfers only. The water temp is 63°F, which is about normal for this time of year.
The real standout? Hold out for Saturday afternoon, the 1st of August. That’s the one. Manly-South Steyne sees a solid 12ft swell from the east, with a period of 8 seconds. The wind is a gentle southerly cross-offshore breeze, keeping it clean. The combined energy is strong (1402). This is big, powerful stuff – over 8ft, so it’s only for experts. The swell direction is east, but this break is sheltered and prefers swell from the south, so it might not be as perfect as it could be. Still, when a 12ft south swell hits with clean cross-offshore wind, it’s a rare treat. Get on it if you’ve got the skill.
The Saturday morning before that, also the 1st, is a 6ft swell from the southeast with a short 5-second period and weak energy (201) – not worth the drive.
Tuesday the 28th and Wednesday the 29th have some size (5ft to 7ft) and clean cross-offshore wind, but the south swell direction isn’t ideal for this spot, and the scores are poor. It’s choppy and messy.
Bottom line: the first week is a write-off. The second week has a few clean windows, but the 1st of August afternoon is the only true standout. Keep an eye on it, but long-range calls are always a bit uncertain.
That’s it from me. Stay salty.
Rusty.
