The Lowdown
Alright, I’m lookin’ at the full 16-day stretch for Trez Hir, and honestly, most of this run is a bit of a struggle. This spot is a rare-breaks setup, so it’s already a challenge to get good surf, and the forecast doesn’t do us too many favours. There’s a long stretch of poor-to-marginal conditions from the start through September 3rd, with the odd moment of ordinary surfable waves but nothing worth paddling out for if you’re hoping for quality. The block from August 27th to September 3rd is a run of mostly messy, cross-onshore winds, short period, weak energy, and a lot of poor surf conditions. It’s a real blank patch.
The water’s sitting at 64° with a small 0.4° anomaly, so it’s about average for the time of year—nothing to worry about.
Now, the real standout—and I mean *the* standout—hits on Friday, September 4th. That afternoon we’ve got a 6 ft swell from the WNW, a nice long 12-second period, and the combined energy pumps up to 1501 (strong wave energy). That’s proper groundswell, and with a quick stiff offshore breeze from the NW, the waves are gonna be clean and lined up. The swell’s over 8 ft in the morning, so it’s pushing big enough to be for experienced surfers only, but the afternoon settles into a solid 6 ft with cross-offshore winds from the WNW, which keeps it really clean. That’s a session worth the wait.
The Friday September 4th afternoon is the best on offer, no doubt. The swell direction matches Trez Hir’s preferred SSW? No, but the WNW is working—it’s exposed, the period’s long, the wind’s good, and the wave quality is tagged as excellent for experienced surfers. The crowd factor is “sometimes,” so you might share it, but it’s worth it.
The rest of the run after September 4th fades back into marginal or poor conditions, with more cross-shore winds and shorter period swell. There’s a brief moment on the morning of September 9th with a 7 ft swell from the W, but period’s only 7 seconds, so it’s a wonky, choppy mess. Sunday September 6th morning has a glassy 4 ft from the W with a 10-second period, but the score’s low and it’s ordinary. Hard to get excited.
Truth is, if you’re mobile and keen, you bank the Friday September 4th afternoon session. The rest of the window is a write-off. Trez Hir’s a rare-breaker, and this forecast shows exactly why.

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.
