The Lowdown

Alright, Rusty here. Let’s have a look at what’s comin’ down for Shark Island in Cronulla over the next couple of weeks. It’s a bit of a mixed bag, so let’s break it down.

The next week and a half is pretty quiet, but there are a couple of moments where it starts to look interesting. The water temp is sitting at 64°, pretty much spot on average for this time of year, so nothing unusual on that front.

We kick off with a bit of a pulse on Thursday the 10th in the morning. Swell is a solid 8 ft from the S with a period of 9 seconds, combined wave energy is moderate at 2014, but it’s a cross-off wind from the SSW at 16 mph, keeping things clean. This is advanced surf at a reef break, so it’s not for the faint-hearted. The swell is big enough that beginners should stay out of the water.

Friday the 11th morning sees the swell drop to 6 ft from the SSE, period still 10 seconds, energy down to 557, and a light cross-off breeze. It’s cleaner and more manageable, but still not a standout.

Now, Saturday the 12th morning is where it gets real interesting. We’ve got clean, glassy conditions with wind coming from the NNW at just 3 mph. The swell is 4 ft from the SSE, period 11 seconds, and energy is moderate at 457. That’s a solid groundswell for the reef, and with the glassy surface, it’ll be pure joy. This is the best on offer in the near term.

After that, we hit a long flat spell. From Saturday afternoon all the way through to Tuesday the 15th, the swell drops right off, with waves barely above knee-high and poor conditions. There’s a gap of a few days where there’s virtually nothing worth paddling out for.

Then Wednesday the 16th morning brings a new pulse: 6 ft from the S, 9-second period, energy hitting 499. The wind is cross-off from the SE at 9 mph, keeping it clean. It’s a bit more consistent but still not a classic.

The next potential highlight is way out on Saturday the 19th morning. The swell jumps to 10 ft from the S, period 10 seconds, and energy is strong at 1984. But the wind is cross-on from the NNW at just 6 mph, so the surface might be a little lumpy. That size is only for experts. It’s promising, but being over a week away, treat it as a maybe.

Sunday the 20th morning stays solid: 7 ft from the SSE, 11-second period, energy 883. Cross-shore wind from the NW at 9 mph, so not clean, but it’s still solid groundswell on the reef.

Later on, Friday the 25th afternoon sees a big spike: 15 ft from the S, 11-second period, and the energy is very strong at 5030. But with a 12 mph onshore wind from the NNE, it’s gonna be a washing machine. That’s kite-surf territory for sure.

So, the standout moment is Saturday the 12th morning – glassy, clean, solid groundswell, and manageable size. The third week looks promising but uncertain. Keep an eye on it.
