Located at an elevation approaching 4,000 feet and an average annual temperature of 61 degrees, Nogales has ideal year-round weather that is always an escape from the heat in Tucson, Phoenix, and Hermosillo. Dry mild winters give way to warm, monsoon soaked summers. Layers with a medium jacket in the winter and fun, breezy clothes in the summer should be just right. Nights can get chilly year-round in the open desert and surrounding mountain areas, while falling below zero in the winters. Snow is rare.
