The Lowdown

Right then, let’s have a proper look at what we’ve got here for Trez Hir (Brittany). Gotta be honest with you, straight off the bat – the first week is a write-off. From the 20th right through to the 25th of July, we’re looking at tiny ankle-snappers, mostly under 1 feet, and the wind is either side-shore or just messy. There’s no energy to speak of – the combined swell energy barely gets into double digits, sitting as low as 4 at one point. You’d be wasting your time even paddling out.

The water temperature is sitting at 63°, which is pretty much bang on average for the time of year, so no surprises there.

Now, things finally start to wake up on Sunday the 26th of July. The swell jumps to 6 feet out of the WNW, but hold your horses – that period is a short, choppy 7 to 8 seconds. It’s got some grunt behind it – the combined energy hits 286 in the morning and 393 in the afternoon – but the forecast warns of marginal conditions. The wind is offshore and clean, but that short period means it’ll be a lumpy, gutless mess for anyone not on a big board. It’s not exactly beginner-friendly either, pushing past 5 feet.

The star of the show, the real standout, is Monday the 27th and Tuesday the 28th of July. This is your window. Monday morning sees 6 feet of WNW swell with a period stretching to 8 seconds, and then it locks in at 5 feet on Monday afternoon with a 9-second period. The combined energy is solid – 370 and 377 – and we’ve got clean, moderate offshore winds from the NNW. Tuesday is even better. The swell drops slightly to 5 feet, but the period hits 10 seconds, and the morning has light offshore winds from the NNW. The energy is cranked up to 386. This is proper groundswell territory – longer gaps between sets, cleaner walls, and that WNW direction is spot on for Trez Hir’s optimum. The waves will be well-shaped and have proper push. It’s sizeable enough for intermediates to have a ball, and with those offshores, the faces will be glassy. Crowds are possible here at times, but with conditions this good, expect company.

After that, it gets patchy again. Wednesday the 29th drops right off to 1 foot, and while Thursday the 30th offers a late-afternoon window of 4 feet with offshore winds and 295 energy, it’s not in the same league. The weekend of the 1st and 2nd of August has some rideable 4 to 4 foot waves, but the period is short (7-8 seconds) and the commentary is just “ordinary”. The second week is a bit of a blur of inconsistent, marginal conditions, though Monday the 4th of August has a late push of 4 feet with offshore wind at 181 energy – worth a look if you’re desperate, but nothing special.

So, to put it plainly: suffer through the first week, then hit Monday the 27th and Tuesday the 28th of July. That’s your best shot at some proper, clean, offshore groundswell at Trez Hir. Anything beyond that in the second week is a gamble and not worth betting on from here.

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.
