Table - best surf conditions forecast for Shark Island (Cronulla) over the next 16 days.
Alright, Rusty here. Let’s get into it.
Right off the bat, the next week or so is looking pretty bleak for Shark Island (Cronulla). We’ve got a long stretch of tiny, weak swell with only marginal conditions at best. Monday the 13th and Tuesday the 14th are basically flat with nothing to ride. Then Wednesday the 15th morning, we see a sudden jump in size to 8ft from the south, with a moderate 10-second period. That brings moderate wave energy (1826), but the wind is a stiff cross-off at 12 mph, so the surface should be clean. However, at 8ft, this is pushing into expert-only territory – definitely not for beginners. The swell direction (S) isn’t ideal for this spot, which likes it more from the SE. It’s a bit of a short-lived pulse too; by the afternoon it’s dropping fast. Wednesday morning is the only time in this whole outlook that really has any punch, but it’s a solid, challenging wave for the experienced crew only.
After that, it’s a real struggle. We drop back to tiny, poor surf from the 16th right through to the 28th of July. You’ll see a few mornings with “surfable waves but very ordinary conditions” – like Saturday the 18th with 2ft from the south, or Tuesday the 21st with a clean 4ft from the ENE – but the energy is weak (100-245), and the quality just isn’t there for a recommendation. The long stretch of nothing means a lot of flat, frustrated days.
The one real standout for anyone who can handle it is Wednesday the 15th of July, morning at Shark Island. It’s the only time the swell gets real, with that 8ft S swell. Wind is cross-off and clean. Crowds are possible here, but on a day this size and with that direction, it’ll be a proper challenge for the advanced crew. Just be aware: with the swell direction not matching the optimum (SE), the waves might not set up perfectly.
Water temp is about average for the time of year, no major anomaly to report.
Bottom line: save your energy for that one Wednesday morning session if you’re a pro. Otherwise, the next two weeks are mostly a write-off.
Rusty.
