Trez Hir Surf Forecast and Surf Report

Alright, it’s your local man Rusty here, and I’ve been staring at the charts for our stretch. Honestly, it’s one of those outlooks where you have to be patient. There’s a big, quiet gap at the start, and the real action is a long way off. Let's wade through it.

First up, Wednesday morning the 6th of August, we get a little pulse at Trez Hir. Swell is a weak 1.0m from the WNW, but it’s only a 6-second period – that’s pure wind slop. Combined swell energy is a pretty weak (109). Wind is a light offshore from the NW, which is a positive, but with that period the waves will be too weak to bother with. For the next week and a half, it’s pretty grim. From the 6th right through to the afternoon of the 16th of August, we see waves that are knee-high at best, with poor conditions and low energy. There will be a few brief windows – like Tuesday the 11th of August where it goes glassy with a 0.6m swell, but that swell is still only 8 seconds, and the energy is only (56) – not worth paddling out for. Thursday the 13th is slightly bigger at 0.9m, but the conditions are just not packing any punch.

Then, things finally get interesting on Monday the 17th of August. On the morning of the 17th, we get a proper jump. The swell hits 1.8m from the west with a 7-second period. The combined energy shoots up to (381), and with the wind going cross-off from the WSW, it’ll be clean. The afternoon gets even bigger – 2.4m from the west. That’s entering the territory where only experienced surfers will want it, especially on a rare-breaking spot like Trez Hir. The energy is massive at (1097). The wind turns straight cross-shore from the SW, so the wave face won't be perfect, but there's meat in the water. It’s inconsistent and rarely breaks, so if it lines up, it could be a proper strike mission, but don't expect it to be easy.

The standout session for the whole 16 days looks to be Tuesday morning, the 18th of August. The swell holds at 2.4m from the WNW. The period is still short at 8 seconds, so it'll be a bit of a freight train – but the wind is solid offshore from the WNW at 30 km/h. That’s going to hold the wave face open and make it clean. The energy is still very strong at (821). For the experts who know Trez Hir, this is the one time in the whole run where the swell direction matches the optimum SSW exposure okay enough, and the wind does the rest. It’ll be too big for most, but if you’re skilled and looking for a slabby, punchy northwest swell, this is your window. The afternoon of the 18th is also decent with 2.3m and the same offshore wind, but the energy drops a little.

From Wednesday the 19th onward, it slowly fades. The 19th of August still offers clean, moderate waves around 1-1.4m with offshore NW winds, but the energy is dropping. By Friday the 21st of August, there’s a glimmer on the charts with a *clean, moderate-swell signal* and energy at (305), but the date is far out. Keep a loose eye on it.

Truth told, apart from that big, powerful window on the 18th, this is a quiet spell. Trez Hir rarely breaks as it is, and a blank run like this is not unusual here. But the 18th? That’s a one-day wonder if the forecast holds.

Rusty.
