Phelan Area Under Red Air Quality Alert As Heat Drives Ozone Levels Higher, Residents Urged To Stay Indoors

PHELAN, Calif. (VVNG.com) — The Phelan area is under a Red Air Quality Alert Monday as excessive heat drives ground-level ozone concentrations higher, prompting health officials to urge residents to stay indoors and limit outdoor activity.

According to a written statement issued on July 20, 2026, by the Mojave Desert Air Quality Management District (MDAQMD), air quality is expected to reach the “Red – Unhealthy for everyone, especially for members of sensitive groups” category on the Air Quality Index (AQI).

Ground-level ozone forms more readily during periods of extreme daytime heat and can significantly reduce breathable air quality. At this level, everyone may begin to experience health effects, while members of sensitive groups, including active adults, children, older adults, and people with heart or lung disease such as asthma, may experience more serious health impacts.

The advisory comes as Phelan is expected to experience several consecutive days of hot, sunny weather, with forecast highs in the mid-to-upper 90s through the week and temperatures nearing 100 degrees by the weekend, conditions that can contribute to elevated ground-level ozone levels.

The district said the advisory may be extended depending on National Weather Service forecasts and future air quality conditions.

Because ground-level ozone cannot easily be detected by sight or smell, MDAQMD encourages residents to check current air quality conditions before spending time outdoors. An AQI reading of 101 or higher is considered unhealthy for sensitive groups, 151 or higher is unhealthy for everyone, and 201 or higher is considered very unhealthy.

Health officials recommend the following precautions in areas affected by poor air quality:

• People with respiratory or heart disease, older adults and children should consider remaining indoors.
• Keep windows and doors closed.
• Run an air conditioner or indoor air purifier if available.
• Avoid using swamp coolers or whole-house fans, which can draw polluted outdoor air inside.

Residents can monitor current air quality conditions by visiting MDAQMD.ca.gov, AirNow.gov or by checking the weather app on their smartphone.
