Table - best surf conditions forecast for Shark Island (Cronulla) over the next 16 days.
The Lowdown
Alright, let’s get into it. This is a tricky stretch for the Cronulla area, with Shark Island (Cronulla) being the only spot on the radar. For the next few days, it’s a tough watch – Friday the 21st through Tuesday the 25th are mostly poor, with small weak swell and messy onshore winds. The first real shift comes Wednesday the 26th afternoon, when a light offshore wind from the WSW starts to clean things up. By Thursday morning the 27th, we’ve got a standout: expect very good surf conditions with a 6ft S swell, period around 11 seconds, and a gentle offshore breeze from the SW keeping things clean. The combined energy is moderate to strong (732), so there’s some push. The water temp is about average for this time of year. That Thursday morning window is your best bet – pick it if you can.
After that, it’s a mixed bag. Friday the 28th offers a fresh offshore in the afternoon, but the swell drops back and the conditions are poor. Saturday the 29th is blown out with strong winds, and Sunday the 30th sees a 7ft NE swell but with lumpy cross-shore winds – that’s more for experienced surfers, and it’s messy. Monday the 31st morning and afternoon bring a return to good conditions with a 5ft ENE swell, clean cross-off winds, and moderate energy. Tuesday the 1st of September starts glassy with a 4ft E swell – that’s another clean, promising session. The rest of the first week of September fades into smaller, less interesting surf. There’s a decent run from Thursday the 27th through Tuesday the 1st, but nothing beyond that really stands out.
Overall, the best on offer is Thursday morning the 27th at Shark Island – clean, solid S swell, and light offshore winds.
