The Lowdown

Alright, let's talk about Trez Hir. This spot is a bit of a tease. It rarely breaks according to the guide, so we need a specific swell and wind combo to get it working. The forecast shows we're in for a lot of close-out, poor-quality days with a few distinct windows where it could get really good, especially for experienced surfers.

Water temp is sitting at about 63°, which is pretty much average for this time of year, so nothing wild there.

We kick off this Friday morning, September 4th, with some lumpy 5ft swell from the W at 8 seconds. The combined energy is a weak 566, and with a cross-off shore wind, it’s looking marginal. Definitely not the session to write home about. By the afternoon, the wind swings offshore from the NW and the swell picks up a touch to 6ft, and the energy bumps to 501. It gets a bit cleaner, but it's still not a standout.

Now, Saturday the 5th is where things get interesting. The morning has a decent 7ft WNW swell with a 13-second period – that's proper groundswell energy, cranking 1488. The wind is a light cross-on from the ESE, though, so it might have a bit of texture. But hold on for the afternoon: clean 6ft WNW swell, 12-second period, and light offshore NW wind. The energy is still a strong 1034 and it's coming from the WNW, which is close to the optimum SSW direction, so it'll wrap in pretty well. This is a real contender for the best session of the whole period.

Sunday the 6th drops right off – small, weak, and onshore. Not worth paddling out.

Monday the 7th is another absolute beauty for the experienced crew. The morning sees 7ft of W swell at a long 13 seconds, with 1487 energy and a cross-offshore wind. That's pumping. It's over 5ft, so it's getting a bit meaty for beginners, but for an intermediate or expert, this is prime. The afternoon is still clean with 7ft and light winds.

Tuesday the 8th cleans up nicely with offshore NW winds, but the swell drops to 5ft and the period shortens a little. Good, but not the same level as Monday.

Wednesday the 9th morning gives us a nice clean 7ft WNW swell with cross-off winds, but it gets sloppy in the afternoon as the wind swings onshore.

The rest of the outlook from Thursday the 10th onward is mostly marginal or poor. There’s a bump on Wednesday the 16th with a clean 5ft swell and offshore wind, which is worth a look, but the main event is clearly Saturday the 5th afternoon and Monday the 7th morning. If you can only pick one, make it Monday the 7th for the power and the clean cross-off breeze. For the bulk of the rest of the two weeks, it's flat or junky. Stay tuned, though – things can change.

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.
