Shark Island (Cronulla) Surf Forecast and Surf Report

Alright, Rusty here. Let me give you the straight-up goods for the Shark Island stretch over the next couple of weeks.

First off, we’re looking at a slow start. The swell is tiny and winds are messy for the first few days, so don't expect much. The water’s sitting at 64°F, which is pretty much spot on for this time of year, nothing unusual. The pick of the whole forecast? That’s gotta be Friday the 11th. Glassy conditions, a clean 4ft of south swell with an 11-second period pushing moderate energy (452), and the wind’s dead calm. That’s the session you want to clear your schedule for. Before that, Thursday the 10th afternoon shapes up nicely too, with 4ft south swell, 11-second period, clean cross-off breeze and moderate energy (462). For a reef break like this, those longer periods mean proper, well-shaped lines.

Now, let’s walk through the timeline. Thursday the 3rd is a write-off – tiny, weak swell and poor conditions. Friday the 4th morning sees a bump to 4ft south swell, 10 seconds, and light cross-off winds – surfable but nothing to write home about. Saturday the 5th is blown out. Sunday the 6th morning has a clean 3ft with a gentle offshore, but it’s small. Monday the 7th is poor. Tuesday the 8th morning brings a serious pulse: 8ft of south swell, 9-second period, with strong to very strong energy (2157). That’s expert territory, big and powerful, but the wind is cross-off so it might be manageable for the skilled crew. The afternoon drops to 6ft but the wind turns cross-shore, making it lumpy. Wednesday the 9th is average, with onshore winds picking up. Thursday the 10th morning is still marginal, but the afternoon cleans right up – that’s a solid session.

After the standouts on the 10th and 11th, it fades. Saturday the 12th and Sunday the 13th are onshore slop. Monday the 14th morning is tiny, then a fresh cross-off breeze picks up in the afternoon for a 4ft south swell, but the energy is only moderate (273) and the conditions are just okay. The rest of the second week – from the 15th right through to the 18th – is mostly poor. There’s a huge spike on Friday the 18th morning: 10ft of south swell with very strong energy (2637), but the wind is onshore and choppy. That’s a mess, more for the kite crew than paddle surfing. A few clean moments pop up on the 17th with light offshore winds, but the swell is small and short-period, so don’t hold your breath.

Bottom line: you’ve got a few days of waiting, then Thursday afternoon the 10th and especially Friday morning the 11th are the ones to chase. After that, it’s pretty bleak for a solid stretch. Still, Shark Island is fairly consistent, so it won’t stay flat forever.

Rusty out.
