The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for Trez Hir over the next couple of weeks. It’s a bit of a slow burner, but there’s a couple of windows that’ll have you reaching for your board.
We start off with a bit of a wait, actually. The first decent showing isn’t until Monday the 7th of September. Monday morning serves up a solid 7ft swell from the west, with a clean 13-second period. The wind is a gentle cross-off, keeping things tidy. The water’s sitting at 64°, which is about average for this time of year, so nothing wild there. The combined wave energy is really pumping at 1512, so there’s plenty of power to play with. Monday afternoon holds up nicely too, with a 7ft west swell, still clean and offshore, energy at 1285. A decent start, but it’s not the best of the run.
Tuesday the 8th, though, that’s a write-off. A 10ft west swell? Sounds big, but with a howling 31 mph north-northwest wind, it’s a mess. The energy is massive at 1169, but you’ll be fighting for your life. This is expert-only territory, and even then, it’s going to be a chore. Definitely not one for the beginners—that’s well over 8ft.
The swell drops off mid-week, with Wednesday the 9th and Thursday the 10th seeing tiny, weak waves. The energy is down in the double digits (125 and 73 on Wednesday), and winds are either offshore or cross-on, but it’s just not worth the paddle. We’re looking at a gap of a few days with nothing really recommendable.
Then, things start to look up. Saturday the 12th of September is the standout. Saturday morning is straight-up glassy—a 3ft west-northwest swell with a very long, juicy 15-second period. The combined energy is a healthy 495, and it’s clean as a whistle. This is a classic low-tide reef wave setup, and with that long period, it’s going to be lined up and perfect. The afternoon builds to 6ft from the same direction, period at 14 seconds, and energy jumps to 1090 with gentle offshore wind. For a break that’s “rarely breaks,” this is a treat. This is the best on offer—crowds are possible, but with those conditions, you’ll be grinning ear to ear.
Sunday the 13th isn’t far behind. A 6ft west-northwest swell with 13-second period, clean cross-off wind, and 1089 energy. It’s a solid, surfable day, maybe a touch more crowded.
The following week has a few more windows. Monday the 21st of September shows potential with a 6ft west-northwest swell, 12-second period, and a gentle offshore wind from the north-northwest. Energy is 850, and it’s looking clean. This one is a bit further out, so keep an eye on it.
The last real highlight is Friday the 18th of September afternoon. A 7ft west-northwest swell with a 12-second period, light offshore wind, and a massive 1186 energy. That’s a proper power session, but with the size, it’s for the experienced crew.
For the rest of the second week, the swell hangs around but the wind gets messy. From the 19th onward, you’re looking at some cross-on or cross-off conditions, and the energy drops off. The 20th has some promise with a 6ft swell and offshore wind, but it’s a bit of a gamble.
Overall, the best bet is Saturday the 12th—that glassy, long-period groundswell at Trez Hir is a rare gem. If you can’t make that, Friday the 18th afternoon is your second shot. The rest of the run is a mix of okay and forgettable.
Stay salty,
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.
