The Lowdown
G’day, Rusty here, your local surf reporter. Let’s look at Shark Island (Cronulla) for the next couple of weeks.
Right now, it’s a pretty quiet start. The first week is mostly flat with small, weak swells. The water temp is about average for this time of year, nothing weird going on there. Tuesday and Wednesday mornings are clean but tiny, with swell around 0.7ft to 1.0ft from the SSE and E – you’re basically just getting wet. Thursday morning has a bit more energy, 2ft from the S, but still poor. It’s not until Friday morning (7th August) that we see surfable waves, but they’re very ordinary – 2ft from the SSE, cross-off wind, clean but weak. Saturday morning (8th August) is similar, with 3ft from the S, still only just surfable, but it’s clean with light WNW wind. The combined energy is only 131 (moderate), so it’s not really pumping.
The real standout is the second week, and it’s a proper big-swell window. On Friday 14th August, the morning sees 10ft from the S, with a combined energy of 1447 (strong) – clean, cross-off wind, but that’s getting into expert territory. For experienced surfers, the best on offer is Saturday 15th August: morning has 15ft from the SSE, period 11 seconds (long period groundswell), and the combined energy is a massive 4796 (very strong). The wind is light to moderate cross-off, so it’ll be clean. This is a big groundswell, so it’ll be best at the reef here – Shark Island is a reef break, so it should handle that long period well. This is for experts only, way too big for beginners. Sunday morning (16th August) keeps that energy with 15ft from the SSE, clean with light NW wind, but watch the cross-shore. Through Monday and Tuesday, the swell drops but stays solid – 8ft to 6ft – still best for those with experience.
The first week has a gap of several days with no real recommendations, from Tuesday 4th to Thursday 6th, then only marginal stuff until the big pulse hits. Crowds are sometimes an issue at Shark Island, so with this swell, expect a few locals out. The period over 11 seconds on Saturday means longer gaps between sets, making paddling out easier, but the reef setup here is perfect for that.
If you’re just starting out, stay away from the second week – it’s all for the experienced crew. The first week is too small to bother with. The big swell on 15th August is the standout, but it’s not for everyone.
Rusty.
