SmogRank / United States

Air quality in Rio Vista

California, United States. Measured until 14 May 2026; not measured today, so it is only on past boards. We make model estimates only for places of 15,000 people or more.

Its measured days

SmogRank measured Rio Vista with ground monitors from AirNow from 2 Jan 2023 to 14 May 2026: 985 days, averaging 11.6 µg/m³. Its monitors stopped giving readings we can use, so it isn't ranked today, but those days stay on the past boards: 985 day boards.
