Blois is best visited during the spring (April to June) and early autumn (September to October) when the weather is pleasant and the crowds are generally smaller.During spring, the gardens of the Château de Blois and other local attractions are in full bloom, making for beautiful scenery. Temperatures are mild, typically ranging from 10°C to 20°C, which is ideal for exploring the town on foot or cycling along the Loire River. This period is particularly good for couples looking for a romantic getaway with comfortable weather for leisurely strolls and outdoor dining.Early autumn also offers agreeable weather, with temperatures similar to spring and fewer tourists than the peak summer months. The changing leaves add a different kind of beauty to the landscape, especially around the Loire Valley châteaux. It's a great time for those who appreciate cooler weather for cycling excursions and exploring the historic sites without the summer rush.While summer (July and August) is popular due to school holidays and warmer weather, it can be quite busy, and temperatures can occasionally be very hot.
