The Lowdown
Alright, gather 'round. This is Rusty, your local surf reporter, checking in for the Trez Hir zone. Let's see what's cookin'.
We've got a solid run of surf on the horizon, but you've got to know when to paddle out and when to stay on the sand. The swell is going to be pumping for the experienced crew early on, and then we'll see a real quiet spell before what could be a cracker of a finish. Let's break it down.
First up, we kick off the period later today, on the 31st of August. We're looking at a solid groundswell from the west, pushing in at 10ft with a 10-second period. The combined energy is up there at (1545), so there’s plenty of power. This is not one for the learners—it's expert territory only. The wind is howling from the WNW at 16 mph, but it's blowing offshore, so the waves will be clean and lined up. The water is sitting at a pretty average 63°, nothing unusual for this time of year. Get your big-wave board if you've got the nerve. This will hold into the afternoon, dropping to 8ft but staying clean with offshore breezes.
Tuesday the 1st of September sees a big drop. The swell is down to 4ft in the morning from the WNW, but the wind swings to a light SSW (6 mph) putting us in a cross-shore. The energy drops right off to (295). It’s a bit sloppy and marginal. Best to give it a miss.
Wednesday the 2nd and Thursday the 3rd are a write-off. The swell is weak, the wind is a messy cross-shore from the SW, and we’ve got poor conditions with a cross-chop. The energy is down in the dumps—stay at home.
Friday the 4th of September looks like a standout morning. We see a new pulse arrive. It’s 5ft from the WNW with a 9-second period, but the real magic is in the afternoon. The wind turns offshore from the WNW at 9 mph, creating clean conditions. The energy bumps up to (415). This is the call for the intermediate surfer or anyone wanting nice, manageable waves.
Then we get our first major highlight. Saturday the 5th of September is the pick of the first week. A strong, very long-period groundswell from the WNW rolls in at 8ft with a period of a massive 13 seconds. The combined energy is a powerful (1841). This swell has serious weight and will be barreling perfectly on the reefs and points. It’s another one for the experts only, with a clean cross-off breeze from the NNW. If you've got the skills for an 8ft+ groundswell with that kind of period, this is your window. The offshore wind holds into the afternoon as well.
The week mellows out completely after that. From Sunday the 6th all the way through to Saturday the 13th of September, it's a dead zone. The swell drops right down, we're looking at tiny waves and a lot of poor to ordinary conditions. It’s a solid 10-day gap with nothing worth paddling for.
But hold on to your board, because the second week brings a potential banger. On Monday the 14th of September, we see a huge swell filling in. The morning kicks off with a 4ft westerly swell, but that’s just the appetizer. The afternoon is where it gets wild: 8ft from the WNW with a 15-second period, pushing an energy reading of (3092). That is a serious amount of power. The wind is offshore from the NNW at 12 mph. Again, this is strictly for the expert crew. It's a long-range call, so keep an eye on it, but the potential is massive.
Tuesday the 15th of September holds that size at 8ft, but the wind gets messy, switching to a cross-off from the WSW. It will still be big and raw, but not as clean as the Monday.
That's the rundown from here. The best bet in the immediate window is Friday afternoon, the 4th of September, for clean, solid waves. For the big dogs, circle Saturday the 5th of September and Monday the 14th of September in your 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.

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.
