The best time to go to Dieppe is between May and September, when the weather is generally warm and pleasant, superb for enjoying the coast and outdoor activities.The summer months of July and August offer the warmest temperatures, ideal for spending time on Dieppe's pebble beach or exploring the cliff-top walks. During this period, the town is at its liveliest, with many shops and restaurants open, and various events taking place, such as the Dieppe International Kite Festival, which is usually held in September. This is a great time for families looking for a traditional seaside holiday with plenty of activities.For those who prefer a slightly quieter experience but still want good weather, May, June, and September are excellent choices. The temperatures are still comfortable for sightseeing and outdoor pursuits, but there are fewer crowds. This period is particularly good for couples interested in exploring the historical sites, such as the Château de Dieppe, or enjoying leisurely strolls along the promenade without the peak summer bustle.
