The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Trez Hir is a tough one to call. The forecast’s a bit of a write-off for the most part, with a long stretch of nothing and then just a couple of moments that might get your heart beating.
First up, the only real standout on the horizon is the morning of Monday, July 27th. The swell is bumping up to 4ft from the WNW, with a period of 8 seconds. The combined swell energy is sitting at a moderate 188, which is some juice, but it's a short period windswell, nothing groundswell about it. What makes this the pick of the bunch is the offshore wind from the NW at 6 mph, keeping things clean. The water temperature is sitting at 63°, which is pretty normal for this time of year, so no surprises there. Now, Trez-Hir is a spot that rarely breaks, so when it does, you need to be on it. It’s fairly exposed to the swell, but that WNW swell direction isn't its optimum – it prefers SSW. Still, with clean conditions, this is your best bet. It’s an intermediate wave, so if you’re a beginner, the 4ft might be a bit much, but it's not a total washout.
After that, the week of July 28th to August 1st is mostly dead. There’s a few tiny pulses and a lot of zeros. The swell just doesn't have the energy to get it working. Then, into the first week of August, we get a couple of glimmers. On the morning of Sunday, August 2nd, we’ve got a 3ft WNW swell, period of 9 seconds. The combined energy is 107, so it’s weak. The real selling point is the glassy conditions – a light wind from the SE, dead calm. That’s rare and will make the surface perfect. The afternoon then turns offshore with a NW breeze, so the whole day is clean. It’s knee-to-waist high, maybe the odd bigger set, but nothing to get too excited about.
The fact is, Trez-Hir is a rare-breaking spot, and this forecast shows exactly why. A long run of small, weak, or non-existent surf. The morning of July 27th is the standout, and the glassy morning of August 2nd is a nice consolation for the patient crew. Keep your expectations low, and your eyes on the horizon.
Rusty.
