The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s brewing for our little corner of the coast.
Honestly, I’m looking at a pretty grim stretch ahead. We’ve got a full 16-day window, but there’s not a single day in there that’s going to get the heart racing. The whole period is a write-off for a proper paddle. The combined swell energy never gets above 167 (167), which is weak to moderate at best, and most of the time it’s under 100 (97). That’s just not enough push to do anything with, especially at a spot like Whitsand Bay and Tregantle, an exposed beach setup that needs a solid, clean SW groundswell. It’s inconsistent here at the best of times, and this run is painfully quiet.
There is a tiny, almost laughable pulse on Tuesday the 4th of August, with a 3ft SW swell at 7 seconds. But the wind is howling onshore from the SSW at 12 mph, and the energy is a weak 97 (97). That’s a messy, blown-out 3ft wave. Not worth getting wet for. Wednesday the 5th sees a slight bump to 4ft from the WSW, but a fresh 19 mph cross-onshore from the WNW will just chop it all up into a lumpy mess. Same story Thursday through Saturday – tiny waves with poor wind. There’s a glassy couple of mornings on Friday the 7th and Saturday the 8th of August, but the swell is just a pathetic 0.3ft. You’d need a hand-lens to see it.
The whole second week is more of the same. A few glimpses of clean cross-offshore winds on the 10th and 12th of August, but the swell is practically non-existent. Later in the run, around the 13th and 14th of August, we see some 2ft waves, but the period is short (8 seconds) and the wind is either cross or onshore, keeping everything choppy and small. By the 18th of August, we get the biggest swell of the entire forecast – 4ft from the WSW – but it’s a short-period 5-second slop with a fresh cross-onshore wind. A 4ft, 5-second wave with a cross-breeze isn’t surf; it’s a washing machine.
Bottom line, there’s nothing to get excited about. For those of you who absolutely need to be on the water, with the strong onshore winds and small, weak swell, this setup honestly looks more interesting for kite surfing. The wave energy just isn’t there for a paddleboard. We’ll have to wait for the forecasts to change.
