The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Trez Hir.
First thing's first, the water's sitting at 63.7°, which is about what you'd expect for this time of year, nothing unusual there. Now, let’s be honest, the first few days are a write-off. The Sunday kicks off with a messy, cross-shore chop and a stormy feel, not worth paddling out for. That flat spell runs right through to Tuesday morning, with only small, weak, and unimpressive waves.
Your first real window of opportunity opens Monday morning, the 31st of August. We've got a solid 8.2ft of swell rolling in from the West-Northwest with a 10-second period. The kicker is a clean, offshore breeze from the Northwest. The wave energy is pumping hard at 1437, so this is for experienced surfers only. The afternoon stays clean and offshore, though the size holds, so it's still a big wave session.
The real standout, though, is Friday the 4th of September. I'm talking about a proper groundswell. The swell is 7.5ft to 8.2ft from the West-Northwest, with a long, powerful 12-second period. The wind is offshore and clean, and the wave energy is massive, hitting 2866 in the afternoon. This is excellent, powerful surf for experienced surfers. Trez Hir is a spot that rarely breaks, so when it lines up like this, it's a special day. The morning of the 5th of September is still worth a look, with a drop in wind to a light breeze and 6.9ft of long-period swell, but it won't quite match the raw power of the day before.
Things tail off after that into the second week. The Monday the 7th of September has a bit of clean, offshore energy with 3.6ft of long-period swell, but it’s a far cry from the earlier standouts. The rest of the second week looks mostly small, weak, and unappealing, with a few glassy but tiny days that aren't worth the drive.
So, for the best of the best, you absolutely want to be on Trez Hir on the morning of Friday the 4th of September. That's the one.

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.
