The Lowdown
Alright, let’s be straight with you. The next couple of weeks are looking pretty average for this stretch of coast. Right now, we're dealing with small, gutless surf and a whole lot of nothing on the horizon for a while. The first few days are a total write-off – tiny waves and mostly poor conditions. There might be a couple of ankle-biters on Friday the 7th, but it's hardly worth the effort.
This dry spell hangs around for the best part of the first week. The swell energy is weak to moderate, with numbers mostly in the 30 to 140 range, and the winds just aren't on our side. There's a bit of a pulse of energy showing up on Monday the 10th, but it's coming with a strong cross-offshore breeze and messy, poor conditions, so it’s not worth getting excited about. You’d honestly be better off staying home and watching the forecast change. But hey, it tends not to stay this poor for long around here, and forecasts can change.
Now, if you're patient, there is one standout window. The real deal is shaping up for the morning of Friday the 14th. That's when we finally see some proper energy and it looks like it’ll be worth a paddle. We're looking at a surfable 4ft of S swell hitting Shark Island (Cronulla). The combined swell energy is a solid 295, so there's a decent push of power behind it, and the W wind should be giving us some clean, cross-off conditions. That morning is your best bet – the afternoon looks like it gets a bit onshore and messy, so make the most of the morning session. This is a reef break for the advanced crew, and it's fairly consistent, so it should be handling this swell nicely. It's a bit of a wait, but that Friday morning looks like the one clean, proper session in the whole fortnight.
After that, things settle back into the ordinary. The following week (from the 15th) sees the surf shrink right back down. There's a brief window on Saturday the 15th with some manageable swell, but it's low-quality and the wind is up, making it a bit of a slog. After that, it’s back to small and weak conditions through the 18th, 19th, and 20th. There is a very brief moment of pure glass early on the 20th, but the swell is basically non-existent at 1ft, so you’d be out there on a flat day. Don't hold your breath for that one.
One last thing – the water temp is sitting around 62°, which is a little cooler than the long-term average for this time of year; you'll feel that nip in the air and water.
So, wrap up warm, be patient, and pencil in that Friday the 14th morning. It's the one to go for.
