The Lowdown
Alright, I’ve got the gen on Trez Hir. Let’s break it down.
First off, the water temp here is sitting at 64°F, which is pretty much bang on normal for this time of year – no surprises there.
The next week and a half is a bit of a drought. There’s a tiny pulse of 6ft swell on Wednesday morning, but it’s only 7 seconds of period and the wind is cross-off. The combined energy is moderate (294), but the quality is marginal. Honestly, it’s not worth rushing out for. The rest of that week and into the next is just ankle-snappers – tiny waves, poor conditions, and a lot of clean but flat spells. There’s almost nothing on offer from Thursday the 6th right through to Sunday the 11th, with wave heights barely hitting 1ft.
We get a slight lift on Monday the 10th morning with a 3ft swell from the WNW, period 9 seconds, and gentle offshore wind. The energy is moderate (147) and it’s surfable, but very ordinary. It’s a small window, and it’s gone by the afternoon.
The real standout, and I mean the only one worth circling on your calendar, is Monday the 17th of August. This is a solid 12ft swell from the WNW, with a period of 11 seconds – that’s proper groundswell with plenty of push. The wind is offshore and moderate, so it’ll be clean. The combined energy is massive (6146 in the morning, 2814 in the afternoon). This is expert territory only – way too big for beginners. Trez Hir is a beach break, but with that long period, expect it to be a bit thick and fast. It’s not a point break, so it might not be perfect, but for experienced surfers, this is the best on offer in the whole 16-day window. Just keep in mind that this is far out, so the call is promising but not locked in.
The second week from the 18th onwards drops back into small, messy surf with varying wind, so don’t get your hopes up after that Monday.

A general guide to surfing at Trez Hir can be found by selecting the local surf guide option on the grey menu.

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.
