The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for our patch, Whitsand Bay and Tregantle, and honestly, it’s a tough one. The next 16 days are looking pretty grim for a proper paddle. We’ve got a real stretch of nothingness here.
We start off with a bit of a whimper, not a bang. The first bit of the run is a write-off. Swell is tiny and it’s coupled with cranky onshore winds. Thursday the 3rd has some waist-high swell at 4ft from the SW, but the wind is a messy 15-18 mph onshore, so it’s just all chop and no shape. The water is a weirdly warm 66°, which is way above normal for the start of September, but that doesn’t help the surf.
The only real spike of energy comes through on the morning of Monday the 7th. We see a big jump in the combined swell energy (1214) with a 6ft swell from the West. That’s a lot of power, but it’s coming with a period of just 11 seconds and a strong cross-shore wind. The notes say "marginal," and I’d agree. It’s a high tide issue or just a messy combo. Too much wind for the size. For a spot that’s fairly inconsistent, that’s a real bummer. After that, it just fades back into a long, flat, or blown-out doldrum.
There’s a brief moment of calm on Tuesday the 15th morning. The wind goes glassy, dead calm, but the swell is a pathetic 3ft with a short period of 5 seconds. It’s surfable, but barely. You’d be scratching for a knee-high slop. The notes say "very ordinary," and that’s a generous way to put it.
Basically, we’ve got a long stretch of nothing. From the 3rd through to the 18th, there’s no standout session. The swell window is open, but the wind just won’t play ball. For a beginner spot, when the swell gets over 5ft, like it does on the 7th, it’s a bit much for the groms, and the wind ruins it for everyone else. For the more experienced crew, the whole 16-day window is a case of ‘don’t bother.’
It’s a quiet spell. It happens. Stick the kettle on, watch the cam, and hope the long-range forecasts start looking better. This is one of those stretches where the setup is more interesting for the kite crew than the paddle crew, especially on those windy, choppy days.
Keep your chin up. Rusty.
