The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s brewing for Trez Hir.

Honestly, the next week and a bit is a bit of a bust. We’ve got a long dry spell on our hands. From Saturday the 18th right through to Saturday the 25th, the wave energy is just pitiful - we’re talking mostly flat or barely a ripple with readings under 100 (21 down to 0). You’d be wasting your time and petrol. The winds are all over the shop, but even when they are offshore, there’s just nothing to push around. The water temp is sitting around 64°, which is pretty average for this time of year, nothing to write home about.

Then, there’s a little flicker of hope. On Sunday the 26th, things start to change. We get a moderate offshore breeze from the WNW, and the swell finally kicks in. Sunday morning sees a 4ft swell out of the WNW, but with only moderate wave energy (213) it feels just ordinary. It's the Sunday afternoon that’s the standout of the whole outlook. We get a clean 4ft swell from the WNW, with the energy really building to a solid 398. That’s moderate-to-strong energy and the offshore wind is going to make it clean. However, this is for Trez Hir, which rarely breaks – so don't get too attached to it delivering. It’s also a small, clean wave so beginners could have a go, but for a spot that’s so fickle, getting solid conditions is pure luck.

Monday the 27th still has some life, with waist-to-chest-high 4ft waves on Monday afternoon and offshore winds, but the energy has dropped back to 175, feeling very ordinary again. After that, we’re back into very small, messy surf through to the end of the period. There’s a long-period 13-second groundswell on the 28th, but it’s only 0.3ft. Not worth a paddle.

So, bottom line: if you’re determined, the best shot you’ve got is Sunday afternoon the 26th, but Trez Hir is inconsistent, so don’t hold your breath. The rest is a write-off.

Rusty.

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.
