Trez Hir Surf Forecast and Surf Report

Right then, let’s have a look at what’s lining up for Trez Hir. I’ll be honest with you, the next week and a half is a bit of a mixed bag, with more than a few days of slop and onshore junk before things start to get interesting. We’ve got a long window here, but the real promise is waiting for us in the second week.

The water temp is sitting at 64°, which is totally normal for this time of year, so no need to worry about a wetsuit change just yet.

The first few days are a write-off. Tuesday the 25th and Wednesday the 26th are poor, with tiny 2ft to 2ft waves from the WNW and cross-onshore winds. The energy is weak, with combined swell energy reading just 97 and 78. There’s nothing to get excited about.

Thursday the 27th sees a bump in size to 5ft from the SW, but the period is a short 6 seconds, and the wind is cross or cross-on. The energy climbs to 209, but it’s still messy and choppy. Not worth paddling out for.

Friday the 28th is a tease. The swell jumps to 7ft from the W, with clean cross-offshore winds, and the energy is moderate at 437 to 596. The model says it’s poor surf, though. The wind is strong (25 mph), and with that much juice and a short period, it’s going to be a washing machine. More of a kite-surfing day than a paddle-surfing day.

Saturday the 29th and Sunday the 30th are marginal. Swell holds around 8ft from the WSW, with cross-off winds and clean conditions, but the energy is getting up there (897 to 962). The forecast says questionable tide conditions. It’s big enough that beginners should stay out, and the short period (8 seconds) won’t help. Monday the 31st is similar, with 8ft waves and clean cross-off winds, but it’s still marginal.

Tuesday the 1st of September drops back down to 5ft, and the wind is back on the cross. Not great.

Now, here’s where it gets interesting. Wednesday the 2nd of September is the first standout. Trez Hir sees 8ft of W swell with a 9-second period, and the wind swings offshore from the WNW. The combined energy is a strong 928, and the forecast says expect very good surf conditions. This is a proper window. The break is a reef setup, and with a long-period groundswell on the way, it should handle the size well. It’s rare for Trez Hir to break, so get on it if you can. The wind is offshore, so the waves will be clean and lined up. Crowds are *sometimes* an issue, so you might have company.

Thursday the 3rd is a no-go with strong cross-shore winds.

Friday the 4th of September afternoon is a sneaky good one. The swell is 4ft from the WNW, with a gentle offshore wind from the NNW (9 mph). The energy is a moderate 412, and the forecast says good surf. It’s a bit smaller, but clean and fun for a longboard or a fish.

Then we get to the big one. Saturday the 5th and Sunday the 6th of September are the real standouts. The swell is 8ft from the W, but the period stretches to 10-11 seconds. The energy is very strong – 1289 and 1404 on Saturday, and 1141 on Sunday. The wind is offshore or cross-off, keeping it clean. This is big, powerful groundswell – over 8ft, so it’s for experienced surfers only. The long period (11 seconds) will give it proper shape and punch, but at a beach break, it might be a bit straight. Trez Hir is a reef, so it should handle that energy beautifully. The forecast says marginal, but the conditions are clean and the energy is there. This is the one to circle.

Monday the 7th and Tuesday the 8th hold similar size (8ft to 10ft) with long periods (10-12 seconds, and even 15 seconds on the 8th afternoon). The energy is massive – 4991 on the 8th afternoon. That is a very strong swell. The wind is cross-off or cross, so it’s still clean. Again, experts only. The 15-second period on the 8th is a very long groundswell; it will be super powerful and make for big, clean lines at the reef, but expect long waits between sets.

Wednesday the 9th of September finishes with a drop to 6ft, but the wind is gentle and cross-off, and the period is 12 seconds. The forecast says good surf conditions. A nice way to end the run.

The Best Bet: If you’re an experienced surfer, lock in Saturday the 5th of September through Monday the 7th of September for the best combo of size, clean winds, and serious energy. It’s a long-range call, so keep an eye on it, but it looks promising. For a smaller, more manageable session, Wednesday the 2nd of September morning is a solid pick.
