The Lowdown
Alright, Rusty here. Let's chew the fat on what Trez Hir has got coming our way.
We've got a slow start to this run, a few days of so-so waves before things get rolling.
Sunday the 13th is a bit of a mess with a light cross breeze. Monday the 14th brings a 3ft swell from the West, but the wind is onshore, making it pretty average. Tuesday the 15th sees the wind go offshore from the Northwest, cleaning up a 6ft swell from the WNW. The combined energy is moderate (563), and the period is a solid 10 seconds. It's rideable, but the real meat is coming.
Wednesday the 16th is when it starts to get good. Wednesday afternoon shows a solid 7ft swell from the WNW, with an 11-second period. The wind is clean offshore from the Northwest, and the combined energy is strong at 1215. This is your best bet for the first part of the run – powerful, clean waves.
Thursday the 17th holds similar size, but the standout is Friday the 18th. Friday morning we see a jump to a 10ft swell from the WNW. That's well over 8ft, so this is for experts only. The period is a very long 14 seconds, giving it massive energy (3273) and shape. The wind is a clean cross-off. This is a big, powerful groundswell day. With that long period and size, it'll work best at a point or reef break; the beach might get a bit straight. Saturday the 19th is still good with a 7ft swell and clean conditions.
The surf backs off through the 20th and 21st, but Monday the 21st morning offers another nice window with a 6ft WNW swell and a long 13-second period, with light offshore winds making for clean waves.
Then we hit a long, quiet patch. From Tuesday the 22nd all the way to Sunday the 28th, it's basically flat or too small and choppy to bother with. A solid week of nothing.
There's a tiny flicker on Monday the 28th with a 5ft WNW swell and a decent 12-second period, but it's not much to get excited about. The combined energy is moderate at 694.
So, bottom line: your standout days are Wednesday the 16th afternoon for a solid, clean session, and the big dog is Friday the 18th for the massive groundswell – expert zone only. After that, it's a long, quiet stretch until the very end.
Stay safe out there.

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.

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.
