You'll find it's superb for outdoor activities like hiking, cycling along the canal, or enjoying the local markets.For those looking to experience the region's full bloom and vibrant countryside, May and June are particularly good. The days are long, and the landscapes are lush, providing excellent opportunities for photography and leisurely drives.If you prefer warmer weather for swimming or spending time by the river, July and August are your best bet. While it can be busier with holidaymakers, the weather is consistently warm, allowing for a full range of water-based activities and outdoor dining experiences.Early autumn, in September, offers a quieter experience with still-mild temperatures and the beautiful changing colours of the foliage.
