It was cold but with little rain. Cold wind but you could still walk down the street. It was a different experience for me being Mexican. But you have to experience everything. It was not as bad as I was told.— This text has been automatically translated into English

Weather Experience: Moderate StarStarStar

We drove around Ireland for a week, had 2 days of rain (in Galway and Dublin), but the remaining 5 days we had alternating sun and showers--perfect weather to drive around in! A couple of days we were able to sit outside and soak up the sun. However, don't choose Ireland for the sun, but bring rain gear and hiking boots and you'll be fine. Fortunately, the showers often pass quickly, as the weather changes very quickly— This text has been automatically translated into English
