Where abouts in Galway? Or Galway city? I love Galway. I think it's one of a few places in Ireland I truly felt like a human being haha. And Clare has some good spots.
I like Dublin to visit but would never want to live there. My best, and only, Irish friend was from Dublin and she 'escaped', only to not make it through the first lockdowns in Ireland. So the place holds bad and sad memories for me. I always loved driving up to the North though, through Sligo and Leitrim. Some beautiful spots there.

Mexico is indeed a huge change. It's cheaper in some ways, but I pay more rent here than in Ireland. But I was extremely lucky to be renting from a 97 year old man who just wanted someone in the house. Now the rents have gone up quite a bit I heard.
There are much cheaper places here in Mexico, but I do like the fact that when we have a power outage, it's never long, while others can be out for days...The luxury comes with a price tag. Tourist areas are expensive but more reliable.

As for the weather, yes, we have pretty good weather here all year around, in our state anyways. Now it's been raining for weeks due to the hurricane season, and it's the first time in my life I actually love it hahaha. I'm from the Netherlands, so it's pretty much rain and clouds like in Ireland...
