Green Valley climate
Desert heat, bright sun, monsoon storms, dry air, mild winters, and cooling shape the year
National Weather Service Tucson climate references provide a 1991 to 2020 Southern Arizona baseline for long hot seasons, bright sun, dry periods, and a summer monsoon pattern. Green Valley's elevation and location south of Tucson can differ from the reference station, so use it as a planning reference rather than a home forecast.
Inspect air conditioning, insulation, windows, roof, gutters, drainage, washes, trees, shade, water, power, internet, smoke filtration, insurance, steps, and the route to care. Keep recreation centers, meals, errands, trails, and indoor options available when heat, dust, or monsoon storms change the day.
