The Lowdown
Alright, this is a bit of a tough one. We’re looking at Trez Hir, and honestly, for the next week or so, it’s going to be a frustrating watch. The water temp is sitting right where it should be for this time of year, nothing unusual there, but the surf is going to take its sweet time to get its act together.
Right off the bat, this Thursday the 27th and Friday the 28th are write-offs. Small, weak, messy swell with a period of only 7 seconds, and the wind is all over the place. The wave energy is pretty anaemic, so it’s not worth paddling out for.
The weekend of the 29th and 30th actually gets some size, but it’s a real mixed bag. Saturday morning the 29th, we’ve got a 8ft swell but it’s coming in with a strong cross-breeze and a messy, lumpy sea. The energy is ramping up, but the quality is terrible. Then Saturday afternoon, it jumps to a 12ft swell from the WSW with a period of 9 seconds, and the wind goes cross-off, cleaning it up. The energy is huge, but that’s proper big, heavy stuff – definitely only for the experienced crew. Sunday the 30th is still big and lumpy, with a storm risk, so not a great time.
The first real glimmer of hope comes Monday the 31st. We’ve got a 10ft swell from the west, period up to 10 seconds, and a clean cross-off wind. The energy is solid. It’s still a big swell, so it’s expert territory, but it’s the first time the conditions look genuinely surfable. Monday afternoon and Tuesday the 1st of September drop off a bit, but still clean.
Now, if you’ve got patience, the standout window is the end of the first week and into the second week. Friday the 4th of September afternoon looks like a little gem. A 5ft swell from the WNW, period of 10 seconds, and a clean offshore wind from the NNW. The energy is good, and it’s the first time we see a “good surf conditions” tag. This is the pick of the bunch for the average surfer. The next day, Saturday the 5th, is also clean but the wind is a bit more variable.
After that, there’s another gap. The 6th of September afternoon has a promising 5ft swell with the same WNW direction and a 10-second period, plus a light offshore from the WNW. That’s another clean session, but it’s a one-off. The rest of the second week is a mix of onshore winds and fading energy, with the 8th and 9th offering small, clean but ordinary waves. The 10th and 11th drop right off to near flat.
So, to sum it up: the best bet for clean, fun waves for the average surfer is Friday the 4th of September afternoon. The bigger, more powerful, expert-only swell hits Monday the 31st of August. Keep an eye on the 6th of September afternoon too, but it’s a short window. This break is “rarely breaks,” so you have to be ready to move when it’s on.
Stay patient, lads. The waiting is worth it for that Friday session.
