Chalchihuites is located in a semi-arid zone, at approximately 8000 feet above sea level. Its thin, transparent atmosphere makes for pleasant, hot days and cool, crisp nights. Consequently, it is advisable to bring light clothing for summer days and a warm sweater for nights at all times of the year. Students may find that, in winter, the townspeople use fewer blankets and heat their homes less than they are accustomed to in their own homes. Therefore, a sleeping bag or an extra blanket may come in handy. It is also recommended to bring sturdy footwear capable of enduring Chalchihuites’ rough cobblestone streets and occasional excursions to nearby sites. Although there are no specific rules as to appropriate dress, many of the local people "dress up" for the frequent dances and "fiestas".
