How do weather patterns in the Loire Valley vary?

In the Loire Valley, significant variations in weather patterns occur across different years, which can greatly influence grape growing and wine production. The region is characterized by a diverse climate influenced by its geography, ranging from cooler areas in the north to warmer sections in the south. This variability means that each vintage can be affected by factors such as temperature fluctuations, precipitation levels, and the timing of seasonal events like bud break and harvest.
