Dublin is twinned with San Jose, but really if there is one American city that Dublin should be twinned with it's Seattle. You've got Microsoft's HQ and all the other tech companies in the area. And, it's often gray and rainy.
Seattle is having an unusually wet November, but despite the rainy, gray weather, Seattle's annual rainfall is not that great. 38 inches a year, which is less than Boston, New York and others. "The rain here has made its name mostly through persistence, not volume. It plays bass, not lead guitar."
That's like Dublin too. In fact, Dublin's annual rainfall is less than Seattle's, just 29 inches per year. It's never the volume, it's the frequency that can get to you.
