Table - best surf conditions forecast for Shark Island (Cronulla) over the next 16 days.
Alright, Rusty here, in feet and miles per hour.
First up, don’t bother paddling out this weekend or early next week. It’s flat and pretty much a write-off. From Saturday the 11th right through until Tuesday the 14th, the swell is tiny – we’re talking ankle-snappers at best, with wave energy barely registering. There’s just nothing to work with, even with clean conditions on Sunday morning. That’s a solid four days of nothing.
Things start to get a little more interesting on Wednesday the 15th. A pulse of south swell pushes in, around 6ft to 7ft, and the energy jumps up. It’s still a bit rough around the edges though – marginal surf with questionable tides. A cross-offshore wind from the south is keeping it clean, but the period is a short 8 to 10 seconds, so it won’t have much push. It’s a beginner-to-intermediate zone at best. Thursday the 16th drops off again, and Friday is back to small.
Now, here’s where we get a little spark. Monday the 20th is worth a look. The swell is a solid 6ft to 7ft from the east, and on Monday afternoon, the wind swings to a light offshore from the southwest, grooming it beautifully. That’s a clean, punchy wave with decent energy and a 11-second period. It won’t be perfect, but for Shark Island, that’s a good session. Tuesday the 21st holds similar size but gets a bit lumpy with cross-offshore wind.
But the real standout – the one you wait for – is Wednesday the 23rd through Thursday the 24th. Wednesday morning sees a chunky 12ft south swell roll in. That’s big, heavy water. On Wednesday afternoon, the wind drops to glassy calm, and we get a 8ft east-southeast swell with a very long 12-second period – groundswell, pure and simple. The water temp is around 64°, which is pretty average for this time of year. Thursday morning gets a 8ft southeast swell with a 13-second period, clean with a light cross-offshore breeze. This is advanced territory – over 8ft, so keep the beginners well ashore. The reef will be working hard, and the sets will be long and powerful. Expect some crowds, because when Shark Island lights up like this, everyone knows.
The pick: Wednesday the 23rd afternoon. Clean, glassy conditions, 8ft of east-southeast groundswell with energy levels through the roof. The pick for experienced surfers only.
Rusty.
