The Lowdown
Gap at the start, folks. The first week and a half is pretty much a flat, blown-out mess at Little Austi and Main Beach. There’s a bit of knee-high slop showing on the 8th with some cross-shore chop, nothing worth paddling out for. A few glassy mornings, like the 7th and 11th, will have you thinking about it, but the swell’s just not there. It’s a waiting game.
The real story is that pulse arriving Thursday the 17th. A proper SSE groundswell builds fast – that’s the standout of the whole run. Thursday morning is looking at 13ft with a 13-second period, and the energy reading is a massive 5172. That’s strong, very strong. The wind is light cross-on, so it’ll be a bit lumpy but far from awful. This is big – over 8ft, so it’s strictly for the experienced crew. The direction is dead on for the ENE exposure, so it should be hitting the bank with some authority. Thursday afternoon holds at 12ft, still solid. That’s your call to arms.
Friday the 18th keeps the size, 10ft in the morning, but the cross-shore breeze builds and it gets messier. Still plenty of grunt in the water, but less clean. The energy is dropping, and by Friday afternoon the onshores are up and it’s getting lumpy. It’s a come-down from the Thursday peak, but there’s still size for those who don’t mind the battle.
Saturday the 19th is the tail end – 6ft in the morning, fading to 8ft by the afternoon with more cross-onshore chop. It’s all a bit average by then. The long-range stuff is promising but less certain, as always. Don’t sleep on that Thursday morning though. That’s the one.
The water’s sitting at 64° with a small positive anomaly, so about normal for this time of year.
