The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the menu for the next couple of weeks.
Straight up, the outlook is a bit of a tough one. There's a long stretch of tiny, junky surf ahead. It's not going to be flat, but it's going to be hard work for a decent wave. The water temperature is sitting at 62°F which is about normal for this time of year, so no surprises there.
The first real chance of anything worthwhile doesn't come until that Sunday morning the 6th of September. We're looking at Shark Island (Cronulla) early that morning. There's a clean 4ft S swell with a light cross-offshore breeze out of the NW. The combined energy is moderate at 275 (kN/m). It's a reef break, so it handles the S swell well, but it's a fairly consistent spot, though it can be inconsistent. The main issue is the tide, which could make it a bit marginal, so keep an eye on that. It's not a standout, but it's the best we've seen in a while.
Then the real standout – and it's a ripper – comes in on Wednesday the 9th of September. The morning session at Shark Island (Cronulla) is where it's at. We're looking at a solid 7ft S swell with a clean offshore breeze out of the S. The combined energy is a massive 1018 (kN/m), which is strong wave energy. That's a powerful S groundswell with a period of 11 seconds, which is a nice long period. This is a proper swell, but it's big. At 7ft, this is advanced territory, especially at a reef break. The wind is clean, so it should be well-shaped, but the period is long enough that it might be a bit tricky at the beach, but a reef like Shark Island should handle it nicely. The afternoon session also holds 7ft of S swell, but the wind swings onshore from the E, so the morning is the go. This is the best on offer, but it's a long way out so keep an eye on the forecasts.
Thursday the 10th still has some size, with 7ft S swell in the morning, but the wind is cross-onshore from the N, which will put a bit of a bump on it. The energy is still very strong at 976 (kN/m), but the quality won't be the same as the 9th.
Beyond that, it drops right back off. The 11th has a clean 4ft S swell, but it's a drop in size and energy, and the 12th and 13th are back to tiny, messy waves. So, the big call is the 9th of September. If you're an advanced surfer and can wait, that's your window. For the rest, it's a classic case of picking your moments for a small, clean wave.
Rusty.
