The Lowdown
Gap of a few flat days first, then we start to see something. Trez Hir (Brittany) is a fickle little setup, rarely breaks, so when it lines up you gotta be there. Water temp’s sitting about average for this time of year, so a good 4/3 will do.
First real chance is Friday the 11th. Morning’s looking the pick with a 5.2ft W swell, period around 10 seconds, light WNW wind and clean conditions. Energy’s moderate at 463. It’s not huge, but it’s got some push. Afternoon drops a touch to 4.3ft but still surfable.
Saturday the 12th is where it gets interesting. Saturday afternoon brings a 4.3ft WNW swell, but the period jumps to 13 seconds – proper groundswell. Combined energy is strong at 712. Glassy cross-off wind. This is a standout. Trez Hir is a reef/rocky setup, and longer period swell loves that kind of break – should be some proper shaped waves rolling through. Sunday morning holds the same energy, 5.6ft and 12 seconds, cross-off, clean. Another good window, but that size and period might be pushing it for anyone not confident in the water.
Then it fades. Monday’s small, mid-week gets messy and onshore, poor conditions. It’s not until Friday the 18th afternoon that things perk up again – 4.3ft WNW, period 9 seconds, gentle offshore, clean. Decent enough.
Then a run of poor days. Small, jumbled lumps.
The real long-range standout is Wednesday the 23rd. Morning shows a 3.9ft WNW swell with a 15-second period – very long period groundswell. Combined energy is strong, 752. Light offshore, clean. This is the one to circle on the calendar. Afternoon’s similar, 4.3ft, 14 seconds, moderate offshore, energy up to 778. It’s a week and a half out, so call it promising rather than locked in. Thursday the 24th morning still has 3.3ft of WNW at 12 seconds, glassy. Could be a nice follow-up.
Overall, this is a quiet stretch with two clear windows: this weekend and that long-range pulse around the 23rd. Don’t sleep on Saturday afternoon.

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.
