When to Go
If the weather is good—and most of the year it isn't—touring Northern Ireland can be a real pleasure. But the place is so green for a reason: lots of rain, which means you should certainly pack your Burberry. Because you're on the coast, even on bright summer days you can feel the chill from the sea, so it's best to wear layers. Needless to say, the weather from May to September is a little friendlier to tourists.
