Tucson, Arizona is located in the Sonoran Desert and has a hot desert climate. Summers are very hot, with temperatures often exceeding 100 degrees Fahrenheit, while winters are mild and pleasant, with temperatures ranging from the 60s to the 70s. Monsoon season occurs during the summer months, bringing short but intense rainfall.

The hydrology of Tucson is primarily influenced by the Santa Cruz River and its tributaries. However, due to extensive groundwater pumping for agriculture and urban development, the river is often dry. The city heavily relies on an underground aquifer system called the Tucson Basin, which provides water for the area.

Tucson offers various outdoor recreation opportunities. The city is surrounded by five mountain ranges, including the Santa Catalina Mountains and the Rincon Mountains, providing ample opportunities for hiking, rock climbing, and camping. The nearby Saguaro National Park is famous for its iconic saguaro cacti, while the Sabino Canyon Recreation Area offers scenic hikes and swimming opportunities. Additionally, Tucson is a popular destination for golfing, road biking, and bird-watching, as it boasts diverse bird species due to its location in the Sonoran Desert.

What is the Eden Index?

The Snoflo Eden Index serves as a comprehensive rating system for regions, evaluating their desirability through a holistic assessment of climate health, outdoor recreation opportunities, and natural disaster risk, acknowledging the profound impact of these factors on livability and well-being.

Climate Health Indicator (CHI): 8.3

Tucson receives approximately 287mm of rain per year, with humidity levels near 47% and air temperatures averaging around 21°C. Tucson has a plant hardyness factor of 9, meaning plants and agriculture in this region tend to thrive here all year round. By considering the ideal temperature range, reliable water supplies, clean air, and stable seasonal rain or snowpacks, the Climate Health Indicator (CHI) underscores the significance of a healthy climate as the foundation for quality living.

A healthy climate is paramount for ensuring a high quality of life and livability in a region, fostering both physical well-being and environmental harmony. This can be characterized by ideal temperatures, reliable access to water supplies, clean air, and consistent seasonal rain or snowpacks.
