The Lowdown
Alright, let's get this straight. I'm lookin' at Whitsand Bay and Tregantle for the next 16 days, and mate, it is a tough stretch. We've got a long flat spell on the cards. The first real sniff of anything worth paddling out for is over a week away, and even then it’s marginal.
The wind's all over the shop for the next week or so, mostly cross or onshore. Swell's tiny. We get a bit of a pulse on the 16th of September, but the wind is messy. The water temp's about average for this time of year, nothing wild there.
Right now, from the 9th through to the 15th, we're lookin' at a solid dead period. Swell is below knee-high and the energy is weak, with values barely hitting triple digits. It’s a write-off. You'd be better off stayin' in bed.
Now, the 16th of September is the only real standout, and it’s not sayin' much. Wednesday morning we get a sudden kick of cross-offshore wind from the SE at 15 mph, which cleans things right up. Swell bumps to 3 ft from the SW, but it’s a short period 6-second windswell, so it’ll be a bit lumpy and lacking punch. The energy is still weak (84). By Wednesday afternoon, the swell jumps to 5 ft from the WSW with a 10-second period, pushin' the energy up to 425 (moderate energy). That’s the best of the bunch. But the wind swings cross-onshore, puttin' a chop on it. Still, for the desperate, that afternoon window is the only show in town. It’s an exposed spot that loves a SW swell.
After that, it drops right back off again into tiny, clean but tiny conditions from the 17th onward. There’s a couple of clean mornings with offshore or cross-off winds, but the swell’s barely a ripple.
Look, if you're a kitesurfer, the 16th afternoon with that 5 ft and cross-onshore wind might look alright. For a paddle surfer? It’s grim. The whole run is inconsistent. This is one of those stretches where you just wait for the forecasts to change.
Stay patient.
