Partly Cloudy Dublin is a city built for conversation, with more pubs per capita than almost anywhere and a literary tradition that produced four Nobel laureates. The Irish capital sits on the River Liffey where it meets the Irish Sea, giving it a temperate maritime climate shaped by the North Atlantic Drift. Summers are cool and long-lit, winters are mild and damp, and rain is a fixture throughout the year. The weather is famously changeable, but as locals say, there is no such thing as bad weather, only the wrong clothing.
