The Lowdown
Right, let's get into it. The outlook for Trez Hir is a bit of a mixed bag, as this spot rarely breaks and needs a certain window. You're looking at a long, quiet start to the period, so don't even bother paddling out for the first few days unless you just want a splash. There's a few decent windows later on that should get the blood pumping.
Things start to look up on the 5th of September, Saturday morning. We get a bit of WNW groundswell of 6ft with a meaty 13-second period, pushing in with a light breeze. The combined energy is a solid (1042), so you'll feel some power. It's a tad on the bigger side, so it might be a little too much for beginners, but for the experienced crew, it’s looking like a proper clean-up.
But the real standout, the one you want to circle on the calendar, is Monday the 7th of September. Early morning, the wind is light and blowing offshore from the NW. The swell is a solid 7ft straight from the west, with that same long 13-second period. The energy is pumping at (1359) – that's proper strong. It's an excellent window for experienced surfers, and given the right tide, this will be the best it gets. After that, the wind tries to switch up on Tuesday the 8th, messing things up with a strong cross-onshore and heavy rain.
There is another little pulse around the 14th of September. Monday afternoon sees a building swell under a light offshore breeze, looking good. Then Tuesday the 15th morning is a solid call, with a 6ft W swell and a 10-second period, in clean conditions and (709) energy. Wednesday the 16th afternoon also offers some clean waves with a longer 11-second period.
Overall, the first week is dead, but the 7th September Monday is the clear winner. The 15th September Tuesday is a solid second pick. Don't expect a marathon of perfect days, but there are a couple of golden hours here if you time it right.

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.
