The Lowdown
G'day, Rusty here. Look, I’ll be straight with you – the next 16 days are a bit of a mixed bag for Shark Island (Cronulla). There’s a decent pulse of swell coming through, but the winds and conditions are gonna make you work for it. The water temp is sitting at 62°, which is about 1° cooler than average for this time of year, so nothing too wild, just a bit nippy.
We start off on Wednesday, July 15th, with a solid 8ft S swell, period of 9 seconds, and a combined energy of 904 (moderate). The morning has a fresh offshore SSW wind at 19 mph, which is a major positive – it’s gonna be clean. This is a standout window for the early part of the week, but it’s an advanced reef break, so it’s not for the faint-hearted. The afternoon sees the wind shift to a cross-off S breeze at 16 mph, still rideable but the swell is a touch smaller at 7ft. The quality is marginal, so pick your tides carefully.
Thursday, July 16th, is a write-off. The wind is howling cross-off at 19-22 mph, and despite the 6ft to 7ft S swell, the conditions are poor. Friday, July 17th, drops off dramatically with a 3ft S swell and weak 102 energy, then even smaller into the weekend. The whole weekend and into Monday, July 20th, is flat and weak – a real gap of poor surf, with the best of it being a 6ft ENE swell on Sunday, July 19th, but the wind is cross-shore and the quality is still marginal.
The real standout window looks like it could be the morning of Saturday, July 25th. We’ve got a clean 4ft E swell with a period of 10 seconds, and light offshore S wind at 6 mph. The combined energy is 307 (moderate), and the forecast says “expect good surf conditions”. This is a promising, cleaner option, but it’s a week and a half away, so keep an eye on it. The morning of Sunday, July 26th, also looks tidy with a 5ft S swell, light offshore W wind, and 362 energy – again, “expect good surf conditions”, but the swell period is short at 6 seconds, so it’ll be a bit wonky.
After that, the last few days of July are mostly small and weak, with the odd clean morning but nothing to get overly excited about. The 2ft to 3ft E swells won’t do much for a reef break that needs a bit of push.
In short: the best bet is the Wednesday morning session on July 15th for the size and clean offshore wind, and the Saturday morning on July 25th for a more relaxed, cleaner day. The rest is a lot of waiting and hoping for a change in the wind.
Rusty.
