The Lowdown
Alright, let’s break it down for Trez Hir.
First things first, the next week or so is looking pretty flat and messy. From Saturday the 1st right through to the 8th, we’ve got tiny waves, mostly knee- to waist-high, with a mix of cross-off and onshore winds that are just killing any chance of a clean wave. The swell energy is weak, mostly under 100, and the swell period is short, around 7 to 10 seconds, so there’s no real grunt behind it. The water temp is about normal for this time of year, nothing to write home about.
But then, things change. The real standout is Sunday the 9th of August, in the morning. We’re looking at an 8ft swell from the west, with a 9-second period. That’s a serious groundswell, and the energy is massive (1909). The wind is offshore from the northwest at 15 mph, so it’ll be clean, glassy, and well-shaped. This is a day for the experienced surfers only – that size at a reef break like Trez Hir is no joke. The sets will be powerful, with long lulls between them, making paddling out a bit easier. Crowds are possible, so get there early if you’re keen.
The afternoon of the 9th will still be solid, with 7ft waves and offshore wind, but the energy drops a bit (576) and the period shortens to 8 seconds, so it’s a little less punchy.
Monday the 10th also has good waves, with 8ft in the morning and 7ft in the afternoon, both from the west-southwest, with light offshore or cross-off winds. The energy is in the strong range (623 and 643). Still a big day for the experts, but the period is only 8 seconds, so it’s more of a windswell feel.
After that, the swell fades again from the 11th onward, with small, inconsistent surf and poor conditions. The 11th has a brief window with 4ft and a 10-second period in the afternoon, giving moderate energy of 285, but it’s nothing special compared to the 9th and 10th.
So, to sum it up: the first week is a dud. The real deal is the 9th and 10th of August, with Sunday the 9th being the absolute best of the lot. That’s the one to circle on the calendar, but it’s only for the experienced crew.

A general guide to surfing at Trez Hir can be found by selecting the local surf guide option on the grey menu. Our Trez Hir surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
