The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cooking at Shark Island (Cronulla). It’s a reef setup, so it’s got that proper feel, but it’s for the advanced crew only. The water temp is sitting about where it should be for this time of year, nothing weird going on.

We’ve got a bit of a slow start, no real action until late in the week. But hold on, because things start to pick up nicely.

Tuesday, July 21st is a write-off. Swell’s there but the wind is all wrong, straight onshore from the NE, and the energy is weak. Don’t even bother.

Wednesday, July 22nd is a bit better. The morning has a clean 3ft swell from the ENE with a light cross-offshore breeze from the WNW. It’s small, but it’s rideable. The afternoon turns glassy with a light NNW breeze and 3ft swell. It’s ordinary, but clean.

Thursday, July 23rd is a write-off again. The swell drops to 3ft and the wind is howling from the W at 15 mph. The energy is weak (107). Not worth a paddle.

Friday, July 24th – now we’re talking. The morning brings a clean 5ft swell from the south with a light offshore wind from the SW. This is the first proper standout. The energy is moderate (421), and the conditions are looking good. The afternoon gets a bit messy with a cross-on breeze, but that morning session is the one.

Saturday, July 25th – another solid day. The morning sees a 5ft south swell, but it’s got a moderate cross-offshore wind from the W. The energy is solid (644). The afternoon cleans right up with a light offshore from the SW and 4ft swell. This is a good run of conditions.

Sunday, July 26th – keep the momentum going. The morning is clean with a light offshore SW wind and 4ft swell from the south. The energy is moderate (326). The afternoon gets a bit of a cross-on breeze, but still good.

Monday, July 27th – the swell drops back to 3ft, and the wind is light but cross-off. It’s surfable, but nothing special.

Tuesday, July 28th – tiny. 2ft swell, weak energy (48). Don’t bother.

Wednesday, July 29th – the morning has a clean 4ft south swell with a light cross-off breeze. The afternoon is weird – a tiny 2ft wave but with a very long period of 21 seconds from the south. That’s a groundswell, but it’s tiny. At a reef, that long period could make for some weird, straight lines.

Thursday, July 30th – the morning is ordinary with 3ft, but the afternoon is a winner. A clean 3ft south swell with a light offshore from the SSW. The energy is moderate (322). Good conditions.

Friday, July 31st – a solid day. The morning is clean with a 4ft south swell and a light cross-offshore breeze. The afternoon is even better: glassy, light offshore from the SW, and the same 4ft swell. The energy jumps to 658. This is a real standout for the week.

Saturday, August 1st – this is the pick of the whole forecast. The morning has a 5ft south swell with a light offshore from the WSW and the energy is pumping at 929. That’s strong wave energy, and the conditions are clean. The afternoon gets a bit of a cross-on breeze, but that morning is a no-brainer.

Sunday, August 2nd – blown out. Onshore wind from the north and messy. Don’t bother.

Monday, August 3rd – the morning has a 4ft south swell with a moderate cross-offshore wind. The energy is high (755), but the wind is strong. The afternoon has a 3ft swell from the SSE with a 16-second period and a fresh wind. That long period will make it tricky on the reef, and the wind is strong.

Tuesday, August 4th – clean but marginal. 4ft swell from the south with a cross-offshore wind. The energy is moderate (357). The afternoon is similar.

Wednesday, August 5th – a clean 4ft swell from the SSE with a light cross-offshore breeze. The energy is moderate (390). It’s surfable, but nothing to get too excited about.

So, the true standouts are Friday, July 24th morning, Saturday, July 25th afternoon, and the absolute best is Saturday, August 1st morning. That 5ft south swell, clean offshore wind, and massive energy (929) is the one to circle on the calendar. It’s a bit further out, but looks promising.

Stay sharp, and don’t sleep on that first Saturday of August.
