The Lowdown
Right, let’s have a look at the 16-day picture for this region. Honestly, it’s a tough stretch. Trez Hir is a rarely breaks kind of spot, and this forecast does not exactly roll out the red carpet. There are long gaps where there’s just nothing worth paddling for. We’ve got a whole heap of days with poor surf conditions and messy winds before we see anything worth a second look.
Friday the 21st of August is your best bet early on, and it’s the only real standout in the whole period. Friday morning brings a clean 6ft swell from the WNW, with a period of 10 seconds and a gentle offshore breeze. That’s proper clean surf, and the wave energy is strong at 512. The water is sitting at 63°F, which is about average for the time of year. It’s a solid little window but it’s brief.
After that, things drop right off. Friday afternoon goes tiny with a 0.3ft swell, and then from Saturday the 22nd right through to Monday the 1st of September, it’s pretty much all poor or marginal. There are days with fresh onshores, lumpy cross-chop, storm risks, and a big 8ft swell mid-period but with near gale winds. That’s kite-surfing weather, not paddling. That gap of no real recommendations lasts for about nine or ten days.
Come Tuesday the 1st of September, we finally see a bit of life. Tuesday afternoon is glassy, with a 4ft swell from the west. It’s not big, but it’s clean and rideable, the wave energy is moderate at 173. Wednesday the 2nd is similar – clean 4ft to 4ft waves with light offshore breezes. It’s ordinary, but it’s surfable. The crowd factor at Trez Hir is listed as sometimes, so you might have company, but it’s not going to be a zoo.
That’s about it. One proper standout on Friday the 21st, then a long quiet spell, and a few small but clean days at the start of September. The longer range stuff on the 3rd and beyond drops off again. Not a classic run, but those first few days and that one morning in late August are worth watching.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Trez Hir may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
