The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the line for Trez Hir.
Right off the bat, I gotta be straight with you – there's a long, quiet stretch ahead. We're looking at a gap of nearly a week before anything worth getting wet for shows up. From now until around the 19th, it's mostly small, weak, and messy. The combined swell energy is pathetic, mostly sitting in the double digits or low triple digits, which is just not enough to get excited about. Winds are cross-off or cross, and the size is barely a ripple. Save your energy.
Now, keep your eyes on Wednesday the 19th. That's when things finally start to look interesting. We've got a pulse of WNW swell pushing in at a touch over 4ft, with a period jumping to 11 seconds – that's real groundswell energy. The wind is offshore from the WNW at about 12 mph, which is going to comb out the surface nicely. The combined energy is up at 399 (moderate), and the break is fairly exposed to this swell direction. This is where it starts to get good.
But the real standout, the one that has me grinning a bit, is Thursday the 20th. The afternoon session looks like the pick of the entire forecast. Same WNW swell direction, bumping up to around 5ft, with that 11-second period still holding. Offshore wind is again from the WNW at 12 mph. The energy jumps to 518 (strong), and the wave comment is positive. This is the best combination of size, wind, and power we see in this 16-day window. Trez Hir is a fairly exposed spot, and with the optimum swell coming from the SSW, this WNW direction is going to wrap in nicely with what the bank wants.
We get a bit of a repeat on Friday the 21st and again on Monday the 24th, with similar offshore conditions and a consistent 4ft groundswell. The energy on the 24th afternoon hits 418, another solid session. Just remember, Trez Hir is a spot that "rarely breaks," so when it does line up like this, you don't want to sleep on it.
By the 25th, the wind swings onshore from the south, and the quality drops right off into the mundane again. The second week fades out with small, choppy leftovers and poor conditions, so your best bet is to focus on that window from the 19th to the 24th.
Water temp is sitting at a mild 65°, which is about normal for the time of year, so no surprises there.
Keep an eye on the charts, and if those long-range pulses hold, we've got a few proper days lined up.
Rusty.

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.
