Sweet spot: March, April, May. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.

- Wicklow's gorse blazes yellow, monastic sites stay open late, and the Newgrange tour queue is a stroll rather than a siege.
- The Newgrange solstice lottery aside, this is fireside-pub season — short days suit Dublin's museums and Kilkenny's medieval mile.
