Best Time to Visit Ireland
The best time to visit Ireland and Northern Ireland are the summer months. This is when the weather is typically drier, and the temperatures are warmer. The spring and fall are also great times to visit as the air will be crisp and the crowds fewer. If this is your first time to visit the Emerald Isle, we do not recommend a visit in the winter.
