G’day, I’m Rusty. Let me walk you through what’s coming up in the local waters.

The first part of the week (through Wednesday, July 8th) is nothing to write home about. The swell is running 8 to 10 ft from the SSE and SE, and it’s packing some solid energy (around 1400 to 2400 units – moderate to strong). But the wind is blowing a steady 19 mph from the SSE and S, cross-off, so it’s not clean. Water temp is about 63°, right on average for the season. With that size, it’s really only for the experts.

Thursday the 9th sees the swell drop to around 7 ft, still from the SE, with the period at 10 seconds. Wind backs off to 12 mph. Still cross-off, but a bit more manageable.

Friday the 10th is the best of the first week. Swell is 6 ft from the SE, period still 10 seconds, and the wind drops to just 6 mph – a light breeze that’ll keep things clean. The combined energy is moderate at 678. By the afternoon, the wind turns offshore from the SSW at 9 mph, making for really nice, lined-up sets. That’s your window.

The standout is Shark Island (Cronulla). It’s a reef break that’s fairly exposed to the SE, which is the direction we’re seeing. It’s an advanced spot, so respect the power. Crowds can show up, but on a Friday with that quality, it’s worth sharing. It’s fairly consistent, so Friday afternoon is the pick.

From Saturday the 11th, it all goes flat. Swell drops to 2-3 ft, periods get short, and the wind goes cross-on or offshore but it’s tiny. Energy numbers drop to the 100s. That’s three days – 11th to 13th – of nothing worth paddling for.

A weak pulse tries to show on Tuesday and Wednesday the 14th-15th, with swell around 6-7 ft from the south, but periods are only 7-8 seconds. Wind is strong – 16-19 mph from the WSW and W, cross-off. It’s lumpy and short-period, not clean.

From the 16th onward, it’s a messy run of small, short-period waves with winds gusting over 30 mph at times, even near gale strength on the 16th. That’s more for the kite crew. Between the 14th and the 21st, there’s no good, clean window to recommend.

So, the bottom line: Friday the 10th is your day. Shark Island (Cronulla) for 6 ft SE swell, clean, offshore wind. After that, it’s a long stretch of small and messy stuff.

Rusty.

A general guide to surfing at Shark Island (Cronulla) can be found by selecting the local surf guide option on the grey menu. Our Shark Island (Cronulla) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
