The Lowdown

G’day, Rusty here. Let’s be straight with you—this stretch for Shark Island (Cronulla) is a bit of a waiting game. The next few days are pretty ordinary, with small, jumbly surf and cross-shore winds that’ll have you fighting for a clean line. Don't bother paddling out just yet.

We start off slow. Saturday the 5th is a write-off—waist-high slop at 2ft, a light northerly putting a chop on it, and not much energy behind it (72). Sunday the 6th cleans up a little with a westerly offshore, but it’s still small at 3ft with a short 7-second period. You’ll get a few crumbly ones, but nothing to get excited about. Monday the 7th is more of the same, bumpy and cross.

Then things start to turn. Tuesday the 8th is the standout of this first week. There’s a proper push of south-southeast swell, chest to head-high at 7ft in the morning, and the wind is light offshore and cross-off. The energy is solid (945) and it’s clean. This is your window. The periods are around 10 seconds, so it’ll have some push to it. This is a reef, so that long-period energy will wrap in nicely, but it’s advanced only—over 5ft, so keep the beginners on the beach.

The next few days after that are a letdown again. Wednesday the 9th has a brief window but a near-gale southerly blows through by the afternoon, turning things messy and blown out. Thursday the 10th has some size—up to 8ft in the morning—but it’s on the stormy side, with a fresh south-southwest breeze. It’s clean-ish, but the quality is questionable and it’s big enough to be expert territory. The energy is strong (925), but it just won’t be your friend unless you really know this place.

Friday the 11th and Saturday the 12th ease off to around 4ft to 5ft with light cross-off winds, giving you clean but average waves. Not bad, not great. Sunday the 13th sees a weird long-period swell (18 seconds) but it’s cross-on and the waves look wonky—that kind of period can close out and be hard to handle here.

From the 14th to the 20th, it’s mostly small and poor. We’ve got a real dry spell. You’ll see a few days with nothing over 4ft, often with onshore or cross conditions. Thursday the 17th has a moment in the afternoon—3ft, glassy, with a light easterly. It’s clean but tiny and slow. Nothing worth planning a session around. The water’s about average for this time of year, not too cold, not warm.

Overall, the only day that really fires is Tuesday the 8th. After that, it's a waiting game. Keep your eye on that Tuesday morning, early, before the breeze swings onshore. The rest is a lot of sitting in the car park.

Rusty out.
