The Lowdown
Alright, Rusty here. Let's break down what's cooking at Trez-Hir.
It's a classic "wait for it" scenario. The first few days are a complete bust with tiny, weak, or messy surf, so hang tight. The first real chance to paddle out is Thursday, August 20th, but even that has its moments.
The absolute standout is the afternoon of Thursday, August 20th. We've got a solid 8ft swell from the WNW, with a 10-second period, and the wind is blowing straight offshore. That's a recipe for clean, well-shaped waves. The wave energy is strong at 971, so it's got plenty of punch. It's a great option for intermediate surfers, but keep in mind Trez Hir *rarely breaks*, so when it's on, it's a real treat. The water temperature is about what you'd expect for this time of year.
Friday, August 21st morning is still decent, with a 6ft WNW swell and offshore winds, but it's a smaller, mellower version. The afternoon drops off to absolutely nothing. Then we hit a long, flat, and messy stretch from Saturday, August 22nd through Tuesday, August 25th. It's all tiny, wind-blown junk, or just flat. Don't bother.
There's a small window on Wednesday, August 26th morning with 5ft swell and cross-offshore winds, but it's only marginal due to tide. The following days are a mix of messy, choppy, or onshore winds. The next real highlight is a bit further out, on the morning of Tuesday, September 1st. We're looking at a solid 7ft WNW groundswell, with a 9-second period and light offshore winds. That's a clean, powerful setup with strong energy (773) and very good conditions predicted. The afternoon of the 1st and Wednesday, September 2nd are also looking clean.
Bottom line: if you can, the best bet is the late afternoon of Thursday, August 20th. If you're planning ahead, the first couple of days of September look promising, but that's a long-range forecast, so keep an eye on it.
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.
