The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Shark Island (Cronulla) over the next couple of weeks.
Right off the bat, things are pretty flat and weak. Thursday the 3rd is a write-off with tiny 2ft S swell and a 10-second period, combined energy a weak 92, and bumpy winds. Not worth paddling out. The first real glimmer comes Friday morning the 4th. We get a bump up to 4ft from the south, period at 10 seconds, and the combined energy jumps to a moderate 283. Winds are light and cross-off, so it’ll be clean. That’s the first call of the run.
Saturday the 5th and Sunday morning the 6th are a mixed bag. Saturday is small and poor, but Sunday morning the 6th is a standout for the early part of the week. Swell holds at 4ft from the south, period stretching to 11 seconds, and combined energy is a solid 289. The wind is offshore from the SSW, light, so expect glassy, clean lines at this reef. This is one of the better windows.
Monday the 7th and Tuesday the 8th get a bit trickier. Monday morning sees 4ft south swell but with cross-shore winds, making it a marginal call. Tuesday morning pushes up to 6ft from the SSE, but period drops to 8 seconds, and combined energy hits 472 – that’s a lot of chop for a short-period swell on a fairly exposed reef. For most, this is more of a kite session than a paddle session.
The real gem of the entire 16-day forecast lands on Thursday the 10th and Friday the 11th. Thursday morning delivers 4ft from the south, period 11 seconds, combined energy a strong 632, with light cross-off winds – that’s clean, powerful, and consistent. Then Friday morning the 11th is absolutely magic: 4ft from the SSE, period 10 seconds, combined energy 381, and it’s glassy – winds from the WSW at just 3 mph. This is the best on offer for the whole run. Get out there if you can.
After that, it drops off hard. Saturday the 12th through to Wednesday the 16th are all poor, with tiny swell and onshore or strong winds. Combined energy dips below 100 often. The water temperature is about average for this time of year, so no surprises there – a 4/3mm or a 3/2mm steamer will do.
The last glimmer is Thursday the 17th morning: 4ft from the south, period 9 seconds, combined energy 265, but it’s flagged as poor surf conditions due to strong cross-off winds at 16 mph. A bit messy, but for the desperate, there might be a wave.
In short: Friday the 4th morning is your starter, Sunday the 6th morning is very good, but the standout is Thursday the 10th morning and especially Friday the 11th morning – glassy, clean, and solid south swell. Don’t sleep on it.
Rusty.
