Understanding Tucson's Desert Climate

Tucson's climate is classified as a hot desert climate (BWh) under the Köppen climate classification. This means it experiences very hot summers and mild winters. The high elevation and proximity to mountains moderate temperatures somewhat compared to lower desert regions.

Key Climate Factors

• Sunshine: Tucson is known for its abundant sunshine, averaging over 300 sunny days per year. This is a major draw for many residents and visitors.
• Aridity: The region is generally dry, with low humidity for much of the year. This can make the heat feel less oppressive than in more humid climates.
• Monsoon Season: From late June to early September, Tucson experiences its monsoon season. This period is characterized by increased humidity, thunderstorms, and intense, albeit often short-lived, rainfall.

In our experience, the monsoon season is the most transformative period for the desert landscape, bringing life back to the arid environment.
