Trez Hir Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Trez Hir. It’s been a bit quiet lately, but the models are showing some pulse coming through, so don’t write this week off just yet. The water temp is sitting at 63°, which is pretty much bang on average for this time of year, so no surprises there.

We kick things off this Saturday morning, 12th September, with a weak little 3ft swell from the west, but it’s on a short 8-second period and the wind is cross-shore, so honestly, it’s pretty average. The energy is low, so I’d wait. By Saturday afternoon, things perk up a bit with a 4ft swell from the WNW, period stretching to 10 seconds, and the wind switches to a nice cross-offshore. The energy jumps up and it’s looking much cleaner. That’s a solid option for a late session.

Sunday the 13th is where it starts to get interesting. Morning brings a clean 5-6ft swell from the WNW with an 11-second period and a cross-offshore breeze – that’s some proper wave energy. This is one of the better windows, with good shape and not too wild. The afternoon holds similar 5ft surf, still clean.

Monday the 14th drops right back off. You’ve got a tiny 3ft cross-on mess in the morning, and a 2-3ft wave in the afternoon. Not worth the paddle.

Now, if you’ve got a bigger board and some experience, keep your eyes on Wednesday the 16th. After a so-so morning, Wednesday afternoon sees a jump to a solid 7ft swell from the WNW, a 12-second period, and proper offshore winds from the NNW. The energy is pumping hard. This is the top standout for the first week – it’s got power, it’s clean, and that swell direction is pure gold for Trez Hir. This is expert territory though; that 7ft is pushing limits for beginners.

Thursday the 17th is still fun, with a 5ft to 5-6ft swell and offshore winds, but not the same punch. Clean lines though.

Alright, now for the real gem. On Friday the 18th morning, we get an absolute beauty. A 7ft groundswell from the WNW, but the period jumps to 14 seconds – that’s a long-period, powerful swell. The energy reading tells you there’s a heap of water moving. The wind is a light cross-offshore, so the waves will be lined up and clean. That said, with a period that long at a beach break like Trez Hir, the sets might stand up a bit walled, but for a bigger board or a step-up, it’ll be incredible. Again, this is strictly for experienced surfers.

We then hit a bit of a lull from the 19th through the 22nd. There’s swell, but the wind gets messy with a cross-shore chop, and the quality drops right off. Sunday the 20th has some size (6ft) and a long 14-second period, but the cross-shore wind chops it up. Not the best.

Then on Monday the 21st, we get a surprise. The morning is glassy – absolutely dead calm with a NNE breeze at just 3 mph. There’s a solid 6-7ft swell from the WNW with a 12-second period. The energy is still high. For the experienced guys, this could be the cleanest session of the whole run. That glassy surface on a 6-7ft wave is a rare gift. One for the diaries.

After that, Tuesday the 22nd fades to 3-4ft, and from Wednesday the 23rd right through to Saturday the 27th, it’s either tiny (1-2ft to 3ft) or onshore junk. There’s a brief flicker on Saturday the 26th with a small clean 3ft offshore wave, but nothing special.

Looking all the way out to the end, Sunday the 27th shows some promise again in the afternoon with a 4-5ft swell from the WNW, a very long 15-second period, and a light cross-offshore breeze. The energy is moderate but that long period will draw some nice lines. It’s a long way off, so keep an eye on it.

Bottom line: The best windows are Sunday the 13th for a clean, solid fun session, and Friday the 18th morning for the big, powerful groundswell. But the absolute standout has to be the glassy Monday morning of the 21st September – 6-7ft, long period, and zero wind. That’s a rare, special morning.

Stay safe out there.
