If you're planning anything outdoors in Dublin, the city is drier than the rest of Ireland by a meaningful margin — the Wicklow Mountains to the south catch most of the rain coming in off the Atlantic, leaving Dublin in a genuine rain shadow. Winters are mild thanks to the Gulf Stream, summers are cool but reliable, and the east coast position means weather here is closer to Welsh or Cumbrian patterns than to Galway or Cork.
