When is the best time to visit Bangor?

Bangor is warmer over the summer months between June and September, although this is also peak tourism season. September is a good time to visit the city if you plan to go further afield and explore, but it can feel rowdier than usual due to the annual university cohort. Both spring and autumn are generally quieter and pleasant, even for camping, while February welcomes the annual Bangor Music Festival.
