The Lowdown
Right, let’s talk this stretch around Point Cartwright/Secrets in feet and knots.
It starts a bit flat and ugly. Monday the 17th into Tuesday the 18th, we’ve got swell running 6 feet from the ESE, but it’s short period – only 7 seconds – and a stiff 16 knot cross-off wind from the SE ain’t helping. Combined energy’s moderate at 391. Water’s 20°, about 1° cooler than average. Surf quality is poor. Not worth the paddle.
Wednesday morning the 19th is your first real chance. Swell drops to 4 feet out of the ENE, but the wind goes offshore from the SSE at only 6 knots. Glassy, clean conditions. Energy’s still moderate at 376. For an advanced break, this is a nice window.
Thursday morning the 20th is another standout. Clear skies, offshore wind 9 knots from the SSE, chest-high 3 feet swell from the SE with a 9-second period. Energy at 244, but the quality is good. Crowds are often, so you won’t be alone.
From Friday the 21st onward, it gets quiet. Swell stays under 4 feet, mostly short period, and winds go onshore or cross-shore. There’s a glassy morning Monday the 24th, but it’s barely knee-high with weak energy (113). You’ll be waiting. This flat spell runs over a week – pretty normal for this area when it goes quiet.
Now, here’s the late hope. Monday the 31st of August afternoon sees a jump to 8 feet from the SE, with a 7-second period and cross-off wind. Energy’s strong at 629. It’s raw but has power. Then Tuesday morning the 1st of September cleans up with a solid 25 knot offshore wind from the SSE, swell at 6 feet from the ESE, and moderate energy at 393. That’s the one to mark on the calendar, but it’s a long way off – consider it promising, not locked in.
Best on offer? Wednesday morning the 19th and Thursday morning the 20th – clean, offshore, fun-sized. For the bigger stuff, wait and see on Tuesday the 1st of September.
Rusty out.
