The Lowdown
Alright, Rusty here. Let’s get into it.
The opening stretch is pretty grim, but there’s a subtle pulse building for the end of the first week and into the second. Nothing huge, but a couple of windows for clean waves if you time it right.
The first real standout is Trez Hir (France) on Saturday the 5th afternoon. The swell is 5ft from the WNW with a nice 11-second period, giving it some proper groundswell energy (combined energy of 518). The wind goes light and cross-off from the NNW, which should keep things clean. This is the pick of the early run. The water temperature is around 63°, which is about normal for this time of year.
Then, Monday the 7th brings a real treat. The morning is glassy, small at 4ft, but the period is a very long 12 seconds, and the energy is already building (499). The afternoon is where it gets special: offshore wind from the WNW, 6ft swell, 12-second period, and a combined energy of 966. That’s proper power. This is the best session on offer. Clean, lined-up, and punchy. If you’re an experienced surfer, this is your window.
Tuesday the 8th pushes into bigger territory – 8ft to 8ft swell from the W and WNW, but the period drops to 8-10 seconds and the wind is cross-off, not pure offshore. Still clean, but the energy is strong (1322 in the afternoon). This is expert-only, and the fat, short-period nature might make it a bit of a wall.
After that, Thursday the 10th morning has a clean 4ft, 10-second WNW swell with light offshore wind from the north. A nice little lull-day option.
The second week gets messy. From the 11th, the wind turns onshore or cross-shore, and the swell gets jumbled with short periods. There’s a pulse on Monday the 14th and Tuesday the 15th with 6ft–7ft WNW swell, but the wind is onshore or cross, and the conditions are marginal. The energy is there (1027 on the 15th morning), but it’s not clean. Not worth paddling out unless you’re desperate.
The final days, 16th, have a drop back to 5ft–6ft with cross-off wind, but the energy is moderate and the quality is just “marginal.” No real standout.
Overall, the best bet is the Monday 7th afternoon session. That’s the one to circle. The Saturday 5th afternoon is a solid backup. After that, keep your expectations low.
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. 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.
