The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s cooking for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch. For a spot that’s *rarely breaks* anyway, this forecast is a real heartbreaker. The whole 16-day window is basically a write-off. From Thursday the 10th right through to Friday the 25th, every single session is tagged as poor surf conditions. That’s a solid two weeks of flat or junk. The wind is almost always a problem, mostly cross-onshore from the west or west-southwest, blowing between 9 and 19 mph. It’s going to be choppy, lumpy, or just plain messy.
You’ll see a few tiny pulses of swell, but they’re small and messy. For example, on Sunday the 13th, there’s a 1 ft swell from the west with a long period of 17 seconds, and the combined energy hits 94 (weak), but the cross-onshore wind at 12 mph will just trash any chance of a clean wave. There’s another little spike on Saturday the 19th with a 0.7 ft swell from the west-southwest and a 13-second period (combined energy of 17, very weak), but again, it’s blown out. The best bit of wind direction we see is on Thursday the 17th and Friday the 25th when we get an offshore flow from the north-northwest and west-southwest, but the swell is so tiny – 0.3 ft to 1 ft – that it’s barely a ripple. The water temperature is sitting around a touch warmer than normal for the time of year at 79°.
Look, there’s no standout here. If you’re desperate for a paddle, maybe the Thursday the 17th morning with that light offshore breeze from the north-northwest at 6 mph might give you a clean, glassy surface, but you’d be chasing 0.3 ft dribblers. It’s more of a swimming day. Otherwise, this is a period to leave the boards in the car and watch the horizon. For a spot that’s already inconsistent, this blank run is pretty normal for the area. Forecasts can change, but right now, it’s a big fat zero.
Rusty.
