The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Straight up, the first few days are a write-off. We’ve got a messy, cross-onshore wind and weak, short-period swell that’s just not doing the job. For Wednesday and Thursday, the waves are small, bumpy, and pretty much unsurfable. You’re better off doing something else.
Things start to turn around on Friday the 4th. The morning is still a bit iffy, but by Friday afternoon the wind swings offshore and we start to see some real energy. The swell jumps to 6ft from the WNW, and with a gentle offshore breeze, Trez Hir is looking clean. The combined energy is moderate (501), and the water temp is sitting at 62°, which is pretty much average for the time of year – nothing unusual there.
The best of the early run is shaping up for Saturday the 5th. The morning swell hits 6ft from the WNW with a long 12-second period, bringing in some nice groundswell energy. The combined energy is strong (1069). The wind is light, though it’s cross-shore, so there might be a little ripple. By the afternoon, the wind eases to a light cross-offshore, and the waves drop slightly to 6ft but stay clean. This is the standout for the first week. Just keep in mind, Trez Hir is a rare break, so don’t expect it to be pumping every day – this is one of those times it’s worth the gamble. Crowds are sometimes an issue here, so be prepared for company.
The middle of the week on Monday the 7th is another good call. Morning sees 5ft from the W with a nice 12-second period and a moderate offshore wind. Clean lines and solid energy (714) – a proper session. Tuesday the 8th is also clean, but the swell is a bit shorter-period and the wind is stronger in the afternoon, so it’s not as good.
From the 9th onward, the swell stays solid, but the winds get a bit dicey. Wednesday the 9th has fresh offshore winds and 6ft swell, but it’s a bit on the strong side. Thursday the 10th sees a big 8ft swell from the west, but it’s short-period (8 seconds) and lumpy – this one is for the experienced crew only. The energy is strong (985), but the quality is marginal.
The real standout, and I mean the real standout, is Tuesday the 15th of September. We’re looking at a 8ft swell from the WNW with a very long 14-second period. The combined energy is massive (2259). The wind is gentle offshore from the WNW, so the conditions are going to be pristine. This is a solid groundswell, and it’ll be clean and powerful. This is for experienced surfers only – it’s too big for beginners. Trez Hir is a rare spot, so when it lines up like this, it’s magic. The long period means the sets will be spaced out, and if it’s breaking straight, the point and reef setup here will handle it beautifully. Mark your calendar.
After that, Wednesday the 16th and Thursday the 17th still have decent surf, but the winds get stronger and the swell drops a bit. Still clean, but not as epic.
Overall, the first few days are a total loss, but from Friday the 4th through to Tuesday the 15th, there are some proper windows. Saturday the 5th and Tuesday the 15th are the two best sessions on offer.
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.

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.
