Willcox AVA Climate

< Back to the Willcox AVA

Climate not only refers to the long-term average of weather conditions like temperature and precipitation, but also to how such averages vary across and between regions, change over time, and are marked by the occurrence of infrequent yet important events. These components can inform winegrape growers on site and variety suitability, vineyard design and infrastructure, vine growth and yield, as well as potential wine styles for which their fruit may be best.
