Current Air Quality Index (AQI) Milpitas

In Milpitas, the local environment defined by a Silicon Valley city near San Jose known for tech industry and suburban communities along with its a coastal inland mediterranean climate with warm, dry summers plays a major role in shaping air pollution patterns. The dominant pollutant in this region is O3, mainly coming from sunlight reacting with vehicle and industrial emissions. This pollutant tends to accumulate under certain weather conditions and worsens the air quality. Continuous exposure to O3 can cause chest pain, coughing, and breathing difficulty, especially among people with respiratory issues, children, and the elderly.
