Best Time to Travel: With spring in the air, New Castle seems to show its best side. All the flowers are in bloom, the ocean water is warmer, and you are sure to see this colourful and vibrant city come to life during the months of September to November. Most European families visit New Castle in Autumn, which makes this the best time to see the city without it being over crowded.
