The Lowdown
Alright mate, suit up, here’s what’s cooking at Shark Island (Cronulla) over the next couple of weeks.
We’ve got a slow start, but the first real opportunity lands on Sunday the 19th. Water temp is 62°, a bit cooler than average for this time of year—nothing crazy but you’ll want a good suit.
Sunday morning the 19th is a beauty. Clean 6ft swell out of the ENE with an 11-second period, light cross-offshore from the SE. Energy is solid at (957). Not huge but perfect for the reef—clean, lined up, real fun. Sunday afternoon drops to 6ft but still clean.
Monday the 20th keeps that 6ft ENE swell rolling in the morning with a light NW cross-off. Monday afternoon the wind turns onshore from the NE at 12 mph and kills it completely.
Tuesday the 21st through to Friday the 24th morning is mostly flat or messy. Friday the 24th morning and afternoon sees a new south swell bump up to 5ft with clean westerly winds and moderate energy (355-399). Surfable but nothing special.
Now the big highlight: Sunday the 26th of July. Morning brings a chunky 8ft south swell with a 12-second period and a light offshore from the SW. That energy reading hits (3264)—that’s serious power. This is for experienced surfers only. Offshore wind will keep it glassy and clean, but that size on the reef is no joke. Afternoon drops to 8ft but the wind shifts cross-shore from the SE, so it gets a bit tricky.
After that pulse, conditions go quiet from the 27th through the 31st—mostly small, onshore, not worth paddling out.
Saturday the 1st of August offers another good window. Morning brings a clean 6ft S swell with a gentle offshore from the SW (855 energy). That’s proper quality for the reef—clean, punchy, manageable.
Sunday the 2nd of August is smaller but clean at 5ft. By Monday the 3rd, a fresh SSW breeze at 22 mph shuts it down.
Your two standout sessions: Sunday morning the 19th for easy fun waves, and Sunday morning the 26th of July for a bigger, more powerful swell for experienced surfers only. Also keep an eye on Saturday morning the 1st of August—solid and clean.
Pick your days, don’t waste your energy on the flat spells.
