This is a great time for outdoor activities like walking along the coast, visiting the Newhaven Fort, or enjoying the local beaches. The pleasant weather ensures a comfortable experience for travellers who appreciate quality and convenience, as you won't have to worry as much about rain or cold.Spring (April to May) and early autumn (September to October) also offer good conditions, often with fewer crowds.
