The Lowdown
Right, pull up a stool, grab a coffee. Rusty here, looking at the charts for the next couple of weeks around Trestrignel, and I gotta be straight with you – it’s a proper slow burn. The first week and a half is pretty much a write-off for anything decent. We’re looking at a long, dry gap from now until about the middle of next week. The surf is just too small and messy, with cross-shore or onshore winds messing up the tiny waves. It’s a real test of patience.
Things finally start to look a bit more interesting around Monday the 17th of August. The swell picks up a little, but the wind is still on it, so it’s nothing to get excited about for a paddle.
The one true standout, the only window that really gets the blood pumping, is the morning of Tuesday the 18th. It’s not a huge swell, but the conditions line up for a magic session. The wind is forecast to go glassy, dead flat calm, which is a huge positive. You’ll have clean, lined-up waves from the WNW at about 6 ft. The energy is right up there (423), which is solid, and the swell has a period of 9 seconds, giving it a bit of push. The only catch is the direction – it’s a bit of a west-northwest groundswell, which can sometimes make a beach break like this close out a bit straight. But with glassy conditions, it’s a gamble worth taking. This is for experienced surfers only, as 6 ft is proper head-high plus and will be powerful.
After that Tuesday morning glory, the wind swings back onshore, and the quality drops again for the rest of the week. We’ve got some more swell on the charts for the 20th and 21st of August, with energy levels around 336 to 368, but the northwest winds are cranking, making it choppy and messy. The conditions just aren't there for a clean ride.
So, bottom line: save your energy for the 18th of August. The rest of the forecast is a waiting game.
Rusty.
