Updates in hr min s Forecast update imminent
G’day, Rusty here. Let’s talk about what’s happening at Shark Island (Cronulla). This is a reef break for the advanced crew, and over the next couple of weeks it’s going to dish up some proper sessions, but you’ll need to pick your moments.
The outlook kicks off Saturday 4 July, but honestly, don’t rush out the door. We’ve got a 4ft S swell with a 12-second period and a cross-off wind, but the energy is weak (333) and it’s only a 1/10 call. The water temp is about average for this time of year. A few waves around, but nothing to write home about.
Sunday 5 July is where the ocean wakes up. A solid 10ft S swell rolls in overnight, period 11 seconds, and a fresh SSW offshore wind of 22 mph blows it clean. The combined energy jumps to a very strong 2050. This is big, heavy stuff – over 8ft, so experts only. It’s a standout for the week, but you better know what you’re doing.
Monday 6 July the swell stays chunky at 8ft with a moderate SSE cross-off, but the energy drops back to moderate (1042) and the conditions are a bit messy. Tuesday 7 July morning offers an 8ft SSE swell with a 16 mph offshore wind, energy in the very strong range (2444). This one’s got power, but it’s still a big boy’s wave.
Now, Wednesday 8 July morning is the true jewel of this forecast. A clear sky, 8ft SSE swell, period 10 seconds, and a gentle 9 mph SW offshore breeze. The combined energy is 2406 – strong. This is excellent for experienced surfers, with clean faces and good shape. A top pick.
Thursday 9 July keeps the size up at 10ft in the arvo, strong energy (3540), but the afternoon cross-off wind makes it more challenging. Friday 10 July morning is another good one: 8ft SSE swell, a moderate offshore, and energy of 1044. Expect very good surf.
Then we hit a gap. From Saturday 11 July afternoon right through to Monday 13 July, the swell drops to under 3ft and the winds turn onshore or cross-shore. The energy plummets (down to 37). A few days of flat, poor conditions. A real lull.
Tuesday 14 July afternoon gets us back in the game. An 8ft S swell, 10-second period, light S breeze at 6 mph, and energy of 1951. Excellent for experienced surfers, and the wind is light enough for clean lines. That’s another highlight.
From Wednesday 15 July onward, the swell ebbs and flows but never really reaches the same heights. Thursday 16 July morning is 7ft but with short period (8 seconds) and crummy cross-off wind. By Friday 17 July the swell drops below 3ft. Saturday 18 July has a brief pulse of 4ft E swell with a 6-second period – short period, poor energy (169). The rest is small and ordinary.
Best on offer: Wednesday 8 July morning for a clean, powerful session, and Tuesday 14 July afternoon for a lighter wind session. Shark Island wants you on your game – big, fast, reefy. Respect it.
Rusty.
