The Lowdown
G’day, Rusty here. Look, I’ve been staring at this stretch of coast for Broadhaven South and, to be honest, it’s a bit of a rough patch for the next couple of weeks. We’ve got a lot of days ahead, but very few of them are going to have you paddling out with a grin on your face. The first week is pretty much a write-off for anything decent, a lot of small, short-period slop with a cross-off breeze messing things up. There’s a gap of about ten days from the 17th to the 26th where the surf is too small and weak to bother with. You’d be fighting for ankle-biters.
The one bright spot in the near term is hiding back there on the 27th of August, a Thursday morning. We see a bit of a pulse of energy coming in, with a 6ft west-southwest swell, a period of 7 seconds. It’s not pretty, but it’s the only time we get over 5ft of proper swell. The wind is offshore from the northwest, which is good, and the water temp is sitting at 65°, which is a touch warmer than usual for this time of year. That’s a notable little bump. But even then, the guidance tells me the conditions are ordinary, so I’d keep expectations in check. That morning is the best of a pretty average bunch, with the swell energy reading at 293. It’s a sheltered spot (Broadhaven South), so it takes a bit to get it going.
After that, it just gets messy again. The wind picks up hard from the west and southwest, blowing 22-28 mph, and the swell stays in the 4ft to 7ft range but gets chopped up and uninviting. The energy readings do jump up, like on the 29th of August with that 10ft swell and a massive energy reading of 2832, but with a strong breeze and cross-off winds, it’s going to be a washing machine. That’s not surf for paddling; that’s more like kite-surfing territory to be honest. The whole setup looks far more interesting for the wind crowd than us wave riders.
So, if you’re desperate, keep an eye on Thursday the 27th. It’s the only real look we get. Beyond that, this stretch of coast is going to be pretty blank for a while.
