The Lowdown
Alright, let's take a look at what's on offer. Just the one spot here, Trez-Hir, and it's a real mixed bag over the next couple of weeks. The water temp is around 65°F, which is pretty much what you'd expect for this time of year, so no surprises there.
From Tuesday the 11th, we're kicking off with a whole lot of nothing. The first few days are tiny, with weak energy, barely registering. The wind is switching around, and the waves are just too small and messy to bother with. You'll see a little bump on Thursday morning the 13th – a 4ft swell from the west with a clean offshore breeze, but the energy is still only moderate. It's surfable, but nothing special.
The real problem is this spot is listed as "rarely breaks," so it needs a decent push to get going. The weekend of the 15th and 16th is a total loss – tiny waves and onshore junk.
Now, circle Thursday the 20th on your calendar. That morning, we've got a solid 10ft groundswell from the west-northwest, with a 12-second period and glassy, dead-calm conditions. The energy is massive, absolutely pumping. That's a big, powerful, clean swell. But it's going to be a heavy one – strictly for the experienced crew. It might be a bit of a gamble with it being a rare-breaking spot, but if it hits, it's the one. The afternoon drops off to nothing, so it's a one-session deal.
Before that, on Wednesday the 19th, we have building swell – 6ft to 7ft from the west-northwest with offshore winds, but the period is short, so it'll be a bit crumbly. The energy is moderate to strong. It's fun, but not the big one.
After the big Thursday, we get another solid pulse on Friday the 21st – 7ft from the west-northwest with a 10-second period and a clean cross-offshore breeze. The energy is pumping. That's a great option, but the wind picks up in the afternoon, so get it done in the morning.
The following week, Monday the 24th, throws up another serious swell – 12ft from the west with a 9-second period. The energy is massive, but the wind is a cross-offshore, so it'll be clean. Again, that's a big wave only for the confident crew. The rest of that week fades out with weaker, wind-affected waves.
So, if you're an experienced surfer, your eyes should be fixed on Thursday the 20th for the glassy, big-swell window, and then Monday the 24th for another big, clean session. For everyone else, the 21st morning is your best bet for a solid, clean wave that's a bit more manageable. It's a spot that needs a lot of love from the ocean, but when it gets it, it can be a blast.

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.
