The Lowdown
Alright, Rusty here. Let’s talk about Trez Hir. It’s a spot that rarely breaks, and for the first ten days, it’s a total bust. We’re looking at a dry spell from now until the 27th of July with nothing worth paddling out for. The water is sitting at about 65°, which is a touch warmer than average for this time of year.
The first real sign of life comes on the morning of the 27th of July. There’s a 4ft swell from the WNW, but it’s got a short period of 8 seconds, so it’ll be weak and a bit disorganized. The wind will be offshore from the NNW, blowing a gentle breeze, so it’ll be clean, but it’s just ordinary surf. The energy is moderate at 212.
The one to circle on your calendar is the afternoon of the 29th of July. That’s the real standout. We’ll get a 4ft groundswell from the WNW with a long period of 11 seconds. The energy jumps to a strong 453, and the wind turns offshore from the WNW with a gentle breeze. This is the best window in the whole 16-day run. The waves should have proper shape and power. But remember, Trez Hir is a rare-breaker, so don’t get your hopes up until you see it with your own eyes.
The first week is a washout, and the second week has only that one promising window. It’s a waiting game, folks.
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.
