The Lowdown
Alright, let's get into it. Manly-South Steyne (reef) is our only spot on the table here, and it’s a bit of a mixed bag for the next couple of weeks.
Right off the bat, there’s nothing firing today, Friday the 31st. The swell is there, around 6 ft to 7 ft from the south, but it’s a cross-off wind and the vibe is marginal. Not worth paddling out for.
Saturday morning, the 1st of August, actually looks like the best of the early run. We’ve got clean 5 ft swell from the SSE with a light offshore breeze from the WSW. The energy is moderate (347), and it’s the most lined-up it’s going to be for a few days. But it’s not a standout, it’s just... okay. The afternoon turns to junk with a light onshore.
Sunday morning the 2nd has a bit more size at 5 ft, and a long 12-second period from the SSE, which gives the waves some push (combined energy 739). But the wind is cross-shore, not ideal. The afternoon goes onshore again.
Then we hit a major lull. From Monday the 3rd right through to Tuesday the 4th, the swell drops to nothing – we’re talking 0.7 ft. It’s flat. Wednesday the 5th shows a pulse, but it’s still weak.
The actual standout window is Wednesday afternoon, the 5th of August. The swell picks up to 6 ft from the south, with a 11-second period, and it’s lined up with a light offshore wind from the west. The combined energy jumps to 695, and it’s the first time we see a "good surf conditions" tag. This is the one to circle. The waves will have some punch, and with that offshore breeze, it’ll be clean. It’s a solid option for the advanced crew.
After that, it’s a slow grind. There’s a small window on Saturday morning, the 8th of August, with 5 ft from the SSE and a light offshore from the WSW, and the energy is moderate (489). That’s the second best option, but it’s not as clean as the 5th.
From the 9th right through to the 15th, it’s mostly small, weak, or blown out. The wind is often cross-shore or onshore, and the swell drops below 3 ft for most of the second week. The 12th and 13th see some strong winds (22 to 28 mph) from the SSW, which will just mess up the surface. Not worth a look.
So, to wrap it up: Manly-South Steyne is a sheltered reef, and it’s not pumping. The best bet is Wednesday afternoon, the 5th of August, with clean 6 ft south swell and light offshore winds. The rest of the 16 days is mostly small, inconsistent, or blown out. Keep your expectations low.
