Shark Island (Cronulla) Surf Forecast and Surf Report

G’day, Rusty here, and I’ve got a look at what’s heading our way for the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.

We’re kicking off with some solid action early on, but it’s not all smooth sailing. The standout period is Tuesday the 8th of September through to Friday the 11th, with the pick of the bunch being Friday morning. That’s where we’ll see the best conditions.

Shark Island (Cronulla) – This reef break is the main show. On Tuesday the 8th, we’ve got a 8 ft SSE swell rolling in with a 9-second period. The combined energy is moderate at 841, and while the wind is a cross-off from the S at 15 mph, it’s clean. The water temp is sitting at 64°, which is bang on average for this time of year. Tuesday afternoon drops a bit to 6 ft SSE, still clean with a light breeze. Not too shabby.

Wednesday the 9th is a write-off – the morning drops to 3 ft, and by the afternoon the wind screams up to 28 mph from the S with a 10 ft swell, but it’s a messy, poor setup. No good.

Thursday the 10th brings a big 10 ft swell from the S with a 9-second period, and the energy jumps to 1501 – that’s strong. But the wind is a fresh cross-off around 19 mph, and the conditions are marginal. This is getting into expert territory (over 8 ft), so only for the experienced crew. The afternoon stays similar at 8 ft S, but still a bit rough.

Now, Friday the 11th morning is the real gem. The swell drops to a more manageable 7 ft from the SSE, with a 10-second period (decent groundswell), and the combined energy is moderate at 848. But the magic is in the wind – a gentle 9 mph offshore from the SSW. That’ll groom the reef beautifully. This is a standout session for advanced surfers, with clean, lined-up waves. The reef setup will handle the long period well, so expect some proper barrels. The afternoon sees a cross-shore wind and a slight drop in quality, but the morning is where it’s at.

After Friday, the surf fades fast. Saturday the 12th has a 5 ft SSE swell but the wind swings onshore by the afternoon, and it’s all downhill from there. There’s a long gap of poor-to-mediocre waves from Saturday the 12th right through to Sunday the 20th of September. The swell drops to under 3 ft most days, with onshore or cross-shore winds and low energy (mostly under 200). Not worth a paddle.

There’s a slight flicker on Sunday the 20th of September morning – a 3 ft S swell with a gentle 9 mph offshore from the WSW. The energy is weak at 182, and the conditions are “surfable but very ordinary.” It’s a small, clean option for a longboard or a mellow session, but nothing to get excited about.

The rest of the outlook runs into the 23rd of September with tiny swells and onshore winds. It’s a flat spell, folks. A few days of glassy conditions on the 23rd morning, but the swell is only 2 ft – not enough to do much.

So, bottom line: get out on Friday the 11th morning for the best of the run. After that, it’s a waiting game.

Rusty.
