When should you visit Dublin?
Dublin's weather is mild and changeable all year, with rain spread fairly evenly across the months. The real differences are daylight, events and hotel prices. Summer has long days and the busiest streets, March brings St. Patrick's Day, and winter is dark early but cozy. Here is how all twelve months compare for weather, crowds, prices and events.

Pack for rain whatever the month, and book your hotel before your flights. Dublin's hotel prices swing hard around big concerts, matches and St. Patrick's Day, so check what is on before you pick dates.
