The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next 16 days around Trez Hir.
Quite honestly, this is a tough stretch. We’ve got a long, quiet spell kicking things off. The first good surf doesn't show up until Wednesday the 19th of August, so there’s a real gap of a few days with nothing to get excited about. The water temps are sitting at 64°, which is basically bang on average for the time of year, so no surprises there.
The first real standout comes on Thursday the 20th of August. The morning session sees a WNW swell pushing 8ft, with a moderate combined energy (1417), but it’s cross-off wind from the WNW at 16 mph. The period is a short 9 seconds, so it’s a bit junky and bumpy. The wave quality is marginal, and with that size, it’s really only for the experienced crew. That afternoon is similar, with the same 8ft swell but a fresh 19 mph breeze, making it lumpy. It’s a window of opportunity, but not a polished one.
The best bet in the whole forecast, and the one I’d circle, is Friday the 21st of August morning. We’ve got a 5ft swell from the WNW with a 10-second period, producing a moderate 444 combined energy. The wind is a light offshore from the NNW at 9 mph, so it’s clean and lined up. The wave comment says "expect good surf conditions," and that’s the first time we’ve heard that. It’s a solid intermediate wave, with a bit of push, and the offshore breeze is a major plus. It’s about as good as it gets in this window.
Later in the forecast, around the 28th of August, we see another pulse. The Friday afternoon sees a 6ft swell from the west, with a 7-second period, and a moderate offshore from the NNW. The energy is moderate (278), and the conditions are described as "expect good surf conditions." It’s a bit short-period, so it’ll be a bit crumbly, but it’s rideable and clean.
The rest of the week is a mix of tiny, weak swells or strong, messy winds. There’s a brief window on the 31st of August, a Monday, with a clean 7ft WNW swell, but that’s a long way out and the wind is light, so it’s a promising but uncertain look.
Overall, for a break that rarely breaks, this is a classic waiting game. The 21st of August morning is your standout. Go get 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.
