The Lowdown
Hey, Rusty here. The next couple weeks have some flash points, but you’ve got to pick your window.
Water’s about average for the season here at 17°. Nothing special in the first few days – flat or ordinary.
The first real highlight is Monday morning the 7th. We’ve got a clean 1.2m south swell, a gentle cross-offshore breeze – that’s nice from the west-southwest. The waves will be holding shape and you won’t be fighting the wind.
But the absolute standout is Tuesday morning the 8th. Swell hits 1.7m from the south, short period but packing 434 units of energy, and it’s glassy clean with a light west breeze. That is going to be firing at Shark Island (Cronulla). Just remember, that size (6 ft) is strong – better for experienced surfers.
Thursday the 10th morning brings a 0.6m swell, but with a crazy 22-second period (that’s very long period, a proper groundswell) and a fresh offshore. It’s only 2 ft, so it’s marginal, but if you’re keen on the reef it could produce a few clean runners.
Into the second week, Wednesday the 16th morning shows 1.7m from the east again, with 427 units of energy and clean cross-off winds. That one’s promising but it’s a long way out.
Don’t bother with the afternoons – most of them are onshore or choppy. The morning of Tuesday the 8th is your best bet. Monday the 7th is a solid second option.
Rusty.
