The Lowdown
Hey folks, Rusty here. So I’ve been staring at the numbers for Devonport Rivermouth, and I’ll level with you – it’s looking like a real dry spell. This kind of dead run isn’t unusual for the spot, but it doesn’t make it any easier to swallow. Over the next 16 days, there’s just about nothing worth paddling out for.
The whole window is plagued by tiny, weak swell. We get a little pulse on Saturday the 22nd with a 7ft swell from the WNW, but the period is only 8 seconds and you’ve got a 30 km/h cross-off wind wrecking it. That’s 548 (moderate energy) but the surface is chopped to bits – not for beginners, not for anyone. That drops to 4ft in the afternoon with the same wind.
After that, we’re in for a long haul. From Sunday the 23rd right through to September 6th, wave heights mostly stay under 3ft. The energy figures are almost all below 100 (weak). Take Monday the 24th: a 4ft swell from the NW, but with a pathetic 5-second period and a cross wind – just lifeless, bumpy slop. It’s the same story day after day, week after week.
There’s a brief clean moment on the morning of September 2nd with glassy conditions and a tiny 3ft NNE swell, but again it’s only 6 seconds – totally gutless. Wednesday afternoon the 2nd sees a bump to 5ft from the NNW, but it’s a 6-second windswell with a cross-onshore wind. That’s a choppy, closing-out mess for experts only, and even then, why bother?
So here’s the truth: this is a full-on gap. No standouts, no hidden gems. Water temp is average for the time of year. If you’re itching to surf, maybe don’t hold your breath. Forecasts can change, but right now it’s a hard pass. Keep the board in the shed.
Stay loose,
Rusty
