The Lowdown
G’day, it’s Rusty here. Let’s be straight with you – the next couple of weeks are pretty ordinary for Shark Island (Cronulla). There’s a big gap of nothing worthwhile on offer right from the start. We’re looking at days of small, messy, or just plain poor surf, with a few brighter spots mixed in. The first real standout doesn’t show up until the 13th, so don’t rush out this weekend expecting magic.
The opening stretch is a write-off. Friday the 7th has a bit of SSE swell at 2ft, but it’s cross-off and weak, with only 136 in the combined energy. Not worth the paddle. Saturday the 8th is smaller again. Sunday the 9th picks up a little, but it’s onshore chop, and that ENE swell is short-period. Monday the 10th has more energy, but a strong cross-shore wind makes it messy. I’d skip all of it.
Tuesday the 11th afternoon offers a glimpse – glassy conditions on a small 2ft S swell. Still, it’s pretty ordinary. Wednesday and Thursday mornings have better winds but the swell drops right off. You’re looking at a lot of days with nothing worth your time.
Now, here’s the one that catches the eye. Thursday the 13th afternoon. The wind swings offshore SW at 12 mph, the swell jumps to a clean 6ft out of the south with a 10-second period, and the combined energy is strong at 664. That’s your standout. It’s going to be proper and lined up, a real step up from everything else. This is the day for advanced crew. The water is 62°, about a degree and a half colder than normal for this time of year, so you’ll want the hood and gloves.
Friday the 14th morning still has a decent 6ft S swell in the water with 779 energy, but the wind goes cross-off W. It’s still good, a solid follow-up, but that offshore Thursday arvo is the pick. The weekend after that drops back down. Saturday the 15th has some S swell but it’s weaker, and then it fades into the following week. The second week is pretty blank, with small, weak swells and only tiny bits of energy. Nothing worth getting excited about.
So, keep it simple. Wait for Thursday the 13th afternoon. That’s the one. The rest is a waiting game.
Rusty.
