Shark Island (Cronulla) Surf Forecast and Surf Report

G'day, I'm Rusty. Let's have a look at the surf outlook for Shark Island (Cronulla). It's a bit of a mixed bag over the next couple of weeks, so we'll have to pick our moments.

The water temperature is sitting at 62°F, which is a bit colder than normal for this time of year, so you might want an extra mil.

We're starting off with a pretty flat spell. Sunday the 23rd and Monday the 24th are a write-off—poor surf conditions with small, messy swell and onshore winds. Looking at the combined energy, it's weak, around 256 (Sunday morning) down to 116 (Monday afternoon), so don't bother.

Tuesday the 25th and Wednesday the 26th are still no good. The swell is tiny and short period, with light rain and onshore winds. The combined energy stays low, under 162, so you're just looking at chop.

Then we get a bit of a tease on Thursday the 27th morning. The wind goes glassy, dead calm, with a 5ft S swell at 9 seconds. That's a moderate energy pulse at 505, and it's clean. Could be a nice little window if you're keen, but it's not a standout. The afternoon turns onshore and rubbish again.

Friday the 28th morning has a little 2ft SSE swell with a clean offshore wind, but it's tiny. The afternoon gets messy with a cross-shore.

Saturday the 29th morning is a no-go—6ft S swell at 9 seconds, but it's cross-shore and choppy. The afternoon, however, shows a bit of promise. A 4ft S swell with a light WSW offshore wind, combined energy at 330, and it's clean. That's a good, clean session on offer.

Sunday the 30th is where things get interesting. The morning has a solid 6ft S swell at 10 seconds, with a clean cross-offshore wind and strong combined energy of 1013. The afternoon pumps up to a 7ft S swell at 10 seconds, with combined energy of 1867 (very strong). The wind is a gentle cross-shore, so it'll have a slight chop, but this is a lot of power. This is the standout period. For a reef break like Shark Island, that long-period S swell will wrap in nicely, and at 7ft, it's expert territory. Keep an eye on the tide.

Monday the 31st goes back to onshore junk, and Tuesday the 1st of September morning is clean but small. The afternoon of Tuesday the 1st has a 3ft SSE swell at 12 seconds with a light offshore wind—clean, but small. That's a longer period groundswell, which will offer some good shape but with long lulls.

After that, it's a long, flat run. From Wednesday the 2nd of September right through to the end of the forecast on Monday the 7th of September, everything is under 3ft with weak combined energy, mostly under 142. The winds are onshore or cross-shore, so it's just not worth paddling out.

So, your best bet: Sunday the 30th. The morning is solid, but the afternoon is the real standout with a 7ft south swell, very strong energy, and manageable wind. It's an expert-only wave at that size at Shark Island, but it's going to be a good one. If that's too big, the Saturday the 29th afternoon offers a clean 4ft south swell with offshore wind.

Stay safe, and I'll see you in the water.
