The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line.
Well, I’ll be honest with you – it’s a pretty quiet stretch ahead. The whole 16-day window is a bit of a flat spell, and we’re starting from a blank canvas. There’s nothing worth paddling out for right now, and it’s going to stay that way for a while. There’s a long gap of over a week with no real surf to speak of. The energy just isn’t there.
Kicking things off, the first real mention we get is around Thursday the 17th of September. Octagon House is exposed to the southeast, and we’ve got a weak pulse of swell coming in from the ESE at about 4ft with a short, choppy period of 6 seconds. The combined energy is still pretty weak at 98, and the wind is a fresh cross-onshore from the east at 19 mph, so it’s going to be lumpy and messy. Not a day for the log, that’s for sure.
That little bump fades quickly. By Friday the 18th, we’re back down to 3ft, same short period, and the wind is still cross-onshore. The water temp is sitting at 87°, which is a touch warmer than normal for this time of year, so at least the bath is nice.
The rest of the outlook is pretty grim. From Saturday the 19th right through to the end of the period on Tuesday the 29th of September, we’re looking at tiny waves – mostly below 3ft – with periods rarely hitting 6 seconds. The combined energy stays in the low double digits or even single digits. There are a couple of moments where the wind goes light or even glassy, like Tuesday the 22nd in the morning, but with swell at just 1.0ft, you’d be better off on a paddleboard.
Nothing here is a standout. There’s no day I’d circle on the calendar. It’s one of those runs where the ocean just takes a breather. For a spot like this, a blank run isn’t unusual, but it doesn’t mean it’ll stay poor forever – forecasts can change. For now, leave the boards in the car.
Rusty.
