The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Shark Island.
Right out the gate, I gotta be honest with you – the next few days are a write-off. We’ve got a bit of swell pushing in, but the wind is just nasty. That cross-off wind is slapping the surface all Thursday and Friday, making a mess of things. The water temp is sitting about average for this time of year, which is no surprise for July. Don't even think about paddling out Thursday; that 7ft to 8ft S swell (538 to 663 combined energy) is all chopped up by a 22 mph wind. Friday and Saturday aren't much better with weak, short-period dribble. A tough start.
Alright, now here’s where it gets a little interesting. Sunday the 19th of July is our first real chance. The wind eases right back to a gentle breeze, and the swell swings around to the ENE at 6ft with a 10-second period. That's got proper energy behind it – we’re talking 726 (combined energy). The direction is actually a pretty good match for this reef. It won't be perfect, but this is the standout session of the whole run. The sets will have some push, and it should be rideable.
Monday the 20th keeps that good energy going with a 5ft ENE swell, and the wind goes light offshore from the WNW in the morning. That is a real window of opportunity. A light 12 mph offshore breeze on a 5ft groundswell? That's clean, lined-up surf. *That* is the best on offer. It's an advanced break at the best of times, and a 5ft swell isn't for beginners, but it's manageable for the crew that know the take-off spot. Crowds can be a thing here sometimes, but that clean morning window should be worth the paddle out.
After Monday, it drops off. Tuesday and Wednesday see the swell backing off to 4ft and then 4ft, with the wind turning onshore in the afternoons, ruining the shape. By the end of the week (the 23rd), the swell is down to under 3ft. It's ordinary, small, and weak with an energy reading dropping into double digits. The last few days of July are flat and messy. There’s a long gap of nothing after Monday, so make the most of that one good morning. Nothing else is worth getting wet for.
Rusty.
