The Lowdown
Alright, Rusty here. Let’s break down what’s on the menu for Trez Hir over the next couple of weeks.
We’ve got a bit of a slow start, but the second half of the week is where it starts to get interesting. Monday morning sees some waist-to-chest high swell from the west, around 7 ft, with a clean cross-off breeze. The water’s sitting at 63°, which is pretty much bang on average for this time of year. The energy is moderate at 1507, but that 13-second period means it’s a proper groundswell – good shape, but it’ll be a bit fat and straight on the beach, so keep an eye on the tide. Monday afternoon cleans up even more with a light offshore wind from the WNW, making for some clean, fun waves.
Tuesday, however, is a write-off. We’ve got a strong NNW wind at 28 mph, blowing offshore but it’s a mess – hard to paddle into, and the waves are short-period and lumpy. Not worth the effort.
Wednesday morning shows a drop in size to 3 ft from the WSW, with a gentle offshore wind. The energy is weak (118), so it’s small and ordinary. Not much to get excited about.
Thursday and Friday are flat and rubbish – small, weak, and choppy. Not worth paddling out.
Now, here’s the first real standout: Sunday, September 13th. The morning session brings a solid 6 ft swell from the WNW, with a 13-second period and a clean cross-off wind. The energy is moderate (1123), and the conditions are set to be very good. This is the best of the first week – clean, consistent, and well-shaped. The afternoon holds similar quality at 5 ft.
Then we hit a bit of a lull Monday and Tuesday morning of the next week, but Tuesday afternoon, September 15th, is a cracker. We’ve got 8 ft of WNW groundswell with a 12-second period, light offshore wind from the NW, and the energy is strong (1496). This is excellent surf for experienced surfers – big, clean, and powerful. It’s a true standout.
Thursday, September 17th, sees a big pulse – 12 ft from the WNW with an 11-second period, but the wind is a strong cross-off at 22 mph. The energy is very strong (3247), but that wind is going to make it a battle. This is expert territory only, and even then, it’s going to be messy. More of a kite-surfing show than a paddle session.
Friday the 18th backs off a bit to 8 ft in the morning with a strong offshore wind, but it’s still a handful. The afternoon improves with a lighter offshore and 7 ft, but it’s still marginal.
The final few days, from the 19th onwards, are mostly cross-shore or onshore winds, with dropping swell and poor conditions. The 20th afternoon is a complete dud – 0.3 ft from the SW. Not worth a look.
The Bottom Line: The best windows are Sunday, September 13th (morning and afternoon) for clean, fun groundswell, and Tuesday, September 15th afternoon for bigger, more powerful, clean waves for the experienced crew. The big pulse on the 17th is for experts only, and even then, it’s windy.
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.
