The Lowdown
Alright, listen up, grab a coffee. Rusty here, looking at the charts for Whitsand Bay and Tregantle. I’ll be honest, this is a grim one. The next 16 days are looking pretty flat and quiet for this stretch of coast. A lot of waiting around, so let’s not sugarcoat it.
We start off with a real dud. From Saturday the 1st of August right through until Tuesday the 11th, it’s mostly a write-off. The swell is tiny, often under 2 feet, and the wind is all over the place. You’ll see a few glassy mornings, like Monday the 3rd and Saturday the 8th, with the odd clean window, but the waves are just too small to do anything with. The combined energy is in the single digits and low double digits, confirming it’s just weak, weak stuff. We’re looking at a solid 11-day gap of poor surf.
Now, the first glimmer of hope, and it’s the only real standout, comes on Thursday the 12th of August. Wednesday the 12th morning, actually. The swell finally wakes up a bit. We’re looking at about 3 feet from the WSW, with a period of 9 seconds. The combined energy hits 139, which is moderate, and the real kicker is the wind: it’s glassy. That’s the magic word. For a spot that’s got a reputation for being inconsistent, this is a rare chance to get some clean, albeit small, waves at Whitsand Bay and Tregantle. The water temp is about average for the time of year, so nothing to worry about there.
But don’t get too excited. By Wednesday afternoon, the wind swings onshore and the energy jumps but the conditions get messy. That morning window is your best and really only shot in the whole 16 days. After that, it’s back to tiny, wind-blown junk for the rest of the run.
So, if you’re keen, pencil in the 12th of August first light. It’s not going to be epic, but it’s the only game in town. For the rest of the time, you’re better off doing something else. This is a tough spot when it’s flat, and the forecasts can change, but right now, it’s a long wait for a small window.
Rusty.
