Trez Hir Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk Trez Hir – it’s a slow start but there’s proper swell building later this week and into next week that’s got me excited. Water temp’s about average for this time of year, nothing unusual.

Monday the 14th is a total dud – tiny 3ft swell from the west with a short 9-second period, cross-onshore breeze making it a mess. Combined energy’s weak at 133, so don’t bother. Tuesday the 15th sees a change: morning is still small (2ft) but a moderate offshore from the NNW cleans it up, and by afternoon we jump to 6ft from the WNW, period 10 seconds, energy 574 – moderate power with offshore wind, solid for intermediates. Wednesday the 16th looks even better: 8ft in the morning, then 7ft in the afternoon with a longer 11-second period and strong offshore wind – combined energy 1208 (strong) – clean and powerful, a real standout. Thursday the 17th has a morning lull, but afternoon brings 7ft WNW swell with offshore wind and 721 energy – another good window.

Now Friday the 18th is where it gets serious: 10ft early with a 14-second period and combined energy 3066 (very strong). That’s a groundswell for experienced surfers only – too big for beginners, and with that long period it’ll be fat at beach breaks but Trez Hir handles it. Offshore wind early, so expect epic, clean waves. The afternoon drops to 8ft but still solid.

Saturday the 19th and Sunday the 20th settle back to 6ft–6ft with cross-off winds – still fun, but not the standout. However, Monday the 21st is another gem: 7ft WNW groundswell with a 14-second period, and glassy conditions from a light easterly breeze in the morning – combined energy 1411 (strong). That’s clean, long-period perfection. Afternoon stays clean with offshore wind.

After that, Tuesday the 22nd through the end of the period fades fast: morning 4ft with moderate energy (341), but winds go cross-off and it’s just okay. From Wednesday the 23rd onward, we’re into a long run of poor surf: small 2ft–4ft swell, onshore winds, and combined energy under 500 – even a few days with zero swell. That gap runs from Wednesday 23rd afternoon all the way to Sunday the 29th, with only a brief glassy moment on Sunday the 27th giving 2ft but weak (144). Not worth paddling out.

The real standouts are Friday 18th morning and Monday 21st morning – both have that long-period, powerful groundswell with offshore or glassy wind. If you’re an experienced surfer, don’t miss those. Trez Hir is inconsistent – it rarely breaks – so when it fires like this, you get on it. Expect crowds on those days, especially the standouts.

Stay keen, Rusty.
