Shark Island (Cronulla) Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Shark Island (Cronulla) is a bit of a slow burn. The first few days are a write-off, with barely a ripple and poor conditions. The standout window is a short pulse of solid, clean swell on Wednesday the 15th of July, but you’ve got to be an experienced surfer to handle it. After that, it’s a long, frustrating stretch of nothing special until the very end.

The first decent surf we see is on Wednesday morning, July 15th. The ocean finally wakes up with a solid 7ft swell from the south, with a period of 10 seconds. That’s a moderate energy push (1488), and with a light offshore wind from the SSW, the waves will be clean and lined up. This is excellent for experienced surfers – but at 7ft, it’s getting too big for beginners. The water temperature is sitting at 63°, which is pretty normal for this time of year, so you won’t need a thick winter suit just yet.

The swell hangs around through Wednesday afternoon, still 7ft from the south, but the wind turns cross-off from the SSE, so it’s still clean. The energy is strong (1382). This is the best of the window, no doubt. Thursday the 16th sees the swell drop to 7ft in the morning, but the period shortens to 8 seconds, and the cross-off wind from the SSW picks up to 25 km/h, making it a bit of a battle. The energy is still moderate (898), but it’s marginal. By Thursday afternoon, the swell is down to 5ft, the wind is howling from the south at 30 km/h, and it’s just poor.

Then we hit a long gap. From Friday the 17th all the way through to Monday the 27th of July, there’s nothing worth paddling out for. The swell is small, often under 3ft, winds are mostly onshore or cross-off but messy, and the energy is weak. A few days show a bit of a cross-shore breeze, but the waves are just too weak and disorganised. It’s a frustrating stretch for a spot that usually offers more.

Finally, on Monday morning, July 27th, we get a glimmer of hope. The swell is only 3ft, but it’s from the east with a very long period of 13 seconds – that’s proper groundswell energy (208). The wind is offshore from the WSW, light at 10 km/h, so the surface will be glassy. The low energy means it’s only surfable in very ordinary conditions, but if you’re patient, you might find a clean, long-period wave. The same pattern continues on Tuesday morning, July 28th, with a 2ft east swell, 11-second period, and a light offshore from the west. Again, it’s small and only for the keen.

The crowd situation at Shark Island (Cronulla) is “sometimes” busy, so on the Wednesday morning standout, expect a few other locals out for the clean 7ft south swell. Because it’s a reef break, that long-period energy will wrap in nicely, but it’s not a spot for beginners.

In short: the only real hit is Wednesday the 15th of July, morning session. Everything else is a wait-and-see, with a small, clean window at the very end of the 16 days. Stay patient, Rusty.
