The Lowdown
Alright, Rusty here. Let's have a look at the forecast for Trez Hir. It's a spot that rarely breaks, so when it lines up, you've got to be on it. We've got a 16-day window, but don't get your hopes up straight away.
The first bit of action worth paddling out for is on Monday the 31st of August. That afternoon we’re looking at a clean 8ft swell from the west, with a moderate offshore breeze from the WNW. The wave energy is strong at (1138), but with a period around 10 seconds, it’s a mix of ground and wind swell. This is the standout session in the whole outlook. The water temp is a touch cooler than average for this time of year at 63°, nothing too crazy.
After that, things go quiet for a solid stretch. From Tuesday the 1st of September right through to the end of the week, the surf is either tiny, a bit messy, or just not worth the drive. A few small clean windows pop up on Friday the 4th and Saturday the 5th, but with a 4ft to 6ft swell and questionable conditions, it's more of a gamble than a guarantee.
The next real highlight doesn't come until Thursday the 10th of September. That afternoon, we’ve got a solid 7ft swell from the west, a clean moderate offshore wind from the WNW, and strong wave energy at (686). The period is a short 9 seconds, so it’ll be a bit lumpy, but it’ll be the best clean swell in days.
Then, on Monday the 14th of September, the ocean really wakes up. The morning starts glassy with a 7ft westerly swell, but the afternoon is the real standout. An 8ft swell from the WNW, very strong energy at (1082), clean cross-offshore winds, and a 10-second period. This is for experienced surfers only – it's big and powerful. Trez Hir is inconsistent, but when it fires like this, it’s a day to remember. The following day, Tuesday the 15th, still has size at 8ft from the WNW, but the wind turns a little onshore, making it messier and harder to manage.
The rest of the forecast fades out. Tides and wind chop it up, and the swell drops off. Keep an eye on that 14th of September. That’s the one to circle on the calendar.
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.
