The Lowdown
Right then, let's have a look at what's on the cards for the next couple of weeks around Trez Hir. I've gotta be straight with you – it's a pretty grim outlook overall. The first half of the period is a write-off for any kind of decent session. We're looking at tiny, weak swell and choppy cross-off winds through Friday the 14th and Saturday the 15th. The swell's hovering around 1 ft to 3 ft with moderate combined wave energy (136 to 222), but it's just messy and not worth getting wet for. Those poor conditions drag on through Sunday and into the middle of next week. There's a real gap here with nothing to get excited about.
Now, Wednesday the 19th of August shows a flicker of hope in the afternoon. We see the swell jump up to 4 ft from the WNW, with a nice clean offshore wind from the NNW. The combined energy bumps up nicely (436), and the period stretches to 11 seconds – that's the makings of a proper groundswell with some push and shape. This is the only real standout of the whole stretch. The water temp is sitting at a pretty standard 65°, which is bang on average for this time of year. The only drama is Trez Hir "rarely breaks", so don't bet the farm on it. It's a rare treat if it does come together. After that, the rest of the forecast is a long, slow fade into nothing. From Thursday the 20th right through to Saturday the 29th, we're looking at tiny waves, mostly under 2 ft, with only a few hints of an offshore wind. The combined wave energy drops right off, often below 100, and the swell period is short. It's lean pickings.
Forget the second week – the period around Wednesday the 19th is your best and only real shot, and even then it's a long-range gamble.

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.
