The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Shark Island (Cronulla) over the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell to get through. The first surf worth paddling out for doesn’t really show up until Wednesday the 5th. Before that, Sunday the 2nd has some chest-high swell at 4.6ft from the SSE with a 12-second period, but the wind is messy and conditions are chopped up, so it’s not a goer. Monday and Tuesday look even worse – tiny, weak, and sloppy. A real nothing stretch.
Wednesday 5th is where things start to turn. The morning is still small with a 2.3ft S swell, but the wind goes offshore from the WSW at 12 mph, and the surf is clean. By the afternoon, it picks up to 4.3ft from the south, the wind drops to 9 mph offshore, and the energy is moderate. It’s a nice little session for the skilled crew – clean, punchy, and not too crowded.
Thursday 6th holds similar size, around 4.6ft to 4.9ft from the south, but the wind wobbles around. The morning is clean with a cross-off breeze, but the afternoon gets a cross-shore chop. Still rideable, but the morning is better.
Friday 7th is the first real standout. The morning delivers a clean 5.9ft south swell with a 9-second period, light WSW wind at 6 mph, and moderate energy. The reef will be offering up some nice lines. The afternoon pushes to 6.6ft from the south with strong energy, but the wind picks up to 16 mph, making it a bit more challenging. For the experienced surfer, the morning session is the pick.
Saturday 8th keeps the fun going with a 5.6ft SSE swell in the morning, clean conditions, and moderate energy. The afternoon gets a bit cross-shore and messy, but there’s still a wave to be had.
We then hit a bit of a lull from Sunday 9th through to Wednesday 12th. Swell drops to around 3.3ft to 4.6ft, winds are ugly, and the surf is poor. A few days of flatness and onshore slop.
Thursday 13th is where things get serious, but it’s for the brave only. A 9.8ft south swell rolls in with a short 8-second period, so it’s going to be a powerful, bumpy, and raw affair. The wind is a strong 25 mph cross-off, so it’ll be clean, but at this size, it’s strictly for experts. The energy is huge.
Friday 14th sees the swell peak with a massive 13.1ft SSE swell, 10-second period, and extremely strong energy. The wind is still a fresh 19 mph cross-off, so it’s clean but huge. This is not a day for the faint-hearted. Only the most experienced chargers should even consider it. The water temperature is about average for this time of year, so no surprises there.
Saturday 15th the swell drops to a still-sizeable 6.9ft, and by Sunday 16th it’s back to 4.6ft with clean conditions and light wind. Monday 17th brings a glassy 4.9ft south swell – a lovely end to the run with smooth conditions.
Best on offer: Friday 7th morning is the standout for the average experienced surfer – clean, solid, and fun. For the big-wave crew, Friday 14th morning is the one to circle on the calendar, but it’s huge and only for the brave.
