The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer for the next couple of weeks down at Whitsand Bay and Tregantle. I’ll be straight with you – it’s a grim outlook for the most part with a lot of barely rideable slop, but there is one little window that has me perking up a bit.

Right now, and for the next week or so, it’s a write-off. We’ve got a long stretch of tiny, weak swell with rubbish onshore winds. From Thursday the 6th right through to Wednesday the 12th, the surf is just a mess. The swell is hovering around 0.3ft to 2ft, mostly from the SW or WSW, with winds swinging onshore or cross-onshore. The combined energy is pathetic, barely hitting double digits most days. It’s frustrating, because the water temp is about average for the time of year, but you’d be fighting a losing battle against the chop.

The one real standout comes on the morning of Thursday the 13th of August. The swell bumps up to 2ft from the WSW, and the period is a solid 10 seconds. That’s a proper groundswell pulse. The wind goes glassy, completely calm. It’s just offshore enough to keep things clean. The combined energy sits at 85 (moderate energy), which is the best we’ll see all period. It’s still not huge, but for a spot that’s rated as inconsistent, this is the moment to go. Expect clean, glassy lines. It’s a beginner-plus break, so that 2ft is perfect. The wind is off, so it’ll be tidy. Keep in mind, crowds are often here, so you might have company.

After that glorious morning, it’s straight back to poor conditions. The rest of the 13th goes onshore, and the following days are a mix of moderate wind and weak swell. Saturday the 15th morning has a 3ft swell from the W with a period of 8 seconds and a light cross-shore, but it’s rated marginal and the combined energy hits 201 (strong wave energy). That’s a lot of energy for a short-period windswell, which means it’ll be lumpy and messy. Not recommended.

The second week from the 16th onward is a dead zone. Swell drops to 0.7ft to 2ft, period is poor, and the wind is onshore or cross-onshore. The combined energy is mostly well under 100. There’s nothing to chase. Long-range certainty is low anyway, but this looks like a proper blank run.

So, my call: if you’ve got a free morning on Thursday the 13th of August, get down early for a glassy session on that 2ft WSW groundswell. That’s your best shot. The rest of the time, you’re better off saving the wax.

Rusty.
