Trez Hir Surf Forecast and Surf Report

Alright, Rusty here. Let's get into it.

First off, the outlook across the whole 16-day window is a bit of a mixed bag for Trez Hir. We’ve got a few days of small, messy stuff before things start to look more interesting. The water is sitting at 62.8°, which is pretty much bang on average for this time of year, so nothin’ to worry about there.

The first decent session kicks off on Tuesday morning, the 1st of September. It’s small, with waves around 4.3ft from the WNW, and the wind is a light cross-offshore breeze. That’ll keep things reasonably clean, but the energy is only moderate (295). It’s a rare break, so you don’t get many chances, but the quality is just okay here. Not a standout, but a start.

The next few days are a write-off. Wednesday and Thursday are all poor conditions with onshore and cross-shore winds, and the swell drops off. The energy is weak to moderate (92-171), and the waves are just choppy and messy. Friday the 4th is a bit bigger, with 4.9ft from the WNW and cleaner cross-offshore wind, but the vibe is still marginal. It’s not firing.

Now, the real standout window. Saturday the 5th is where things get interesting. We’ve got a solid 4.9ft swell from the WNW, but the period jumps to 12 seconds – that’s proper groundswell. The combined energy is strong (626). The wind is light and cross-offshore, so the surface will be clean. This is for the more experienced crew, as the waves have some punch. It’s a rare break, so when it’s like this, it’s a proper treat.

But the absolute best on offer is Monday the 7th of September. Morning session has 6.6ft of WNW swell at 11 seconds, with light offshore winds from the NNW. The energy is very strong (987). The afternoon is just as good, with 6.2ft and clean offshore winds from the NW. This is expert-level stuff – over 5ft, so it’s not for beginners. The shape will be good, and with that long period, the set waves will be well-defined. This is the one to circle on the calendar, but remember, it’s a rare break, so don’t expect it to be crowded, but it might be a little busy.

Tuesday the 8th is another solid day, with 6.6ft from the WNW in the afternoon, good energy (778), and clean conditions. The morning is a bit smaller but still clean. The period drops to 10 seconds, so the waves will be a bit more frequent.

After that, the surf fades. Wednesday the 9th is still rideable but the rain showers and moderate wind make it less attractive. From Thursday the 10th right through to Saturday the 13th, it’s mostly small, weak, and poor. The energy drops to between 35 and 122, and the waves are under 2.6ft. Not worth paddling out.

Then, a late-week surprise. Monday the 14th of September has a fantastic afternoon session. The swell is 5.2ft from the WNW, with a 12-second period and light offshore winds from the NNW. The energy is very strong (919). This is another standout for the experts, with clean, powerful waves. The morning is a bit onshore, but the afternoon is the pick.

The 15th and 16th of September are smaller (3.3-4.3ft) but still have that long-period groundswell. The wind is offshore and clean, so the waves will be well-shaped but not as punchy. A good option for intermediates with the right gear.

So, to sum it up: the best windows are Monday the 7th and Monday the 14th of September, with the afternoon of the 7th being the absolute top pick. The 5th and 8th are also very good. Everything else is either small, poor, or marginal. Get out there when it’s on.
