The Lowdown

Alright, grab a coffee and listen up. We’re looking at a pretty flat and frustrating stretch here at Shark Island (Cronulla). The water temp is sitting at 63°F, which is about average for this time of year, so no surprises there.

The next handful of days are basically a write-off. From Tuesday the 1st right through until the end of the first week, we’ve got poor surf conditions with tiny swell and wonky wind. The wave energy is weak, barely hitting triple digits, and the best we get is a “surfable” but very ordinary 2ft bump on Wednesday afternoon. Don’t bother paddling out for that.

There’s a solid gap of nothingness until we hit Wednesday the 9th. That’s when the charts finally start to look interesting. Wednesday morning sees a jump in size with a 8ft south swell, period hanging around 10 seconds, and cross-off winds from the south at 25 mph. But the real standout is Wednesday afternoon and Thursday morning on the 10th. Wednesday afternoon delivers a 8ft south swell (11-second period) with a gentle cross-shore, creating clean conditions. The combined energy hits 1944 – that’s strong, powerful stuff. Thursday morning keeps the momentum with an 8ft south swell (12-second period), light cross-shore winds, and the energy peaking at 2046. This is genuine groundswell with a long period, and for a reef break like Shark Island, that’s the sweet spot. The waves will have shape and power, and the lighter winds will keep it glassy. This is the best on offer, but it’s expert territory – 8ft is big, so only for the experienced crew. Crowds are possible here at times, so expect some company out back.

After that, Thursday afternoon turns onshore and messy, and the rest of the forecast drops back into tiny, poor surf through to the end of the 16-day window. The energy fades right down to 27 by Sunday the 13th. For a break that’s fairly consistent, it’s a long dry spell, but the good news is that when it does come, it comes with serious power.
