The Lowdown

Alright, let’s get into it. I’m lookin’ at Trez Hir, and I gotta be straight with you – it’s a tough stretch ahead. This spot is a rare one, and for the next 16 days, it’s lookin’ like a whole lot of nothin’ on the surf front.

The water temp is sitting at about 66°F, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber, but honestly, that’s the only bright spot.

We kick off on Wednesday the 15th, and it’s already a bust. Tiny swell, 1ft from the west, with a short period – not worth paddling out for. The wind is cross-off, but the energy is just pathetic, reading at 34 (very weak). The whole first week is a write-off. Thursday through Sunday the 18th-19th, we’re scraping by with 0.7ft to 1ft waves. The wind goes from cross-off to full cross, and by Sunday it’s a strong breeze with messy chop. There’s just no push.

We go into a real dry spell from Monday the 20th right through to the end of July. The swell stays tiny, barely a ripple. The wind is mostly cross or cross-off, but without any size, it’s just a flat lake. The energy numbers are all in the teens or low twenties (weak). There’s one moment on Saturday the 25th afternoon where we get a little 2ft from the west with offshore wind, and the energy bumps up to 42 (still weak), but it’s just not enough to get excited about.

Then on Tuesday the 28th, we see a little promise with a 1ft west-northwest swell, period at 11 seconds, and light offshore winds in the morning. The energy is 31 (weak). It’s the cleanest the water will be, but the size is just too small for a proper wave.

Look, to be honest, there’s no standout day here. The best on offer is probably the Tuesday the 28th morning, just because it’s glassy and clean, but you’d be surfing ankle-biters. Trez Hir is a rare break, and this forecast is a classic example of why. It’s a long stretch with no real surf. I’d say keep an eye on the charts, but for now, leave the board at home.

Information about the Trez Hir Surf forecast

The above surf forecast table for Trez Hir provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Trez Hir) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
