Air quality today

The air quality in Bakersfield today is classified as Moderate. The primary pollutant identified is PM10, with a measured concentration of 107.0 µg/m³, while fine particulate matter (PM2.5) registers at 6.9 µg/m³ based on eight valid observations.

What the data includes

Bakersfield’s OpenAQ feed includes six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), fine particulate matter (PM2.5) and coarse particulate matter (PM10). The data come from three monitoring stations that together contribute 19 recent rows of observations. The most recent updates were recorded on 2026‑02‑11 at 00:00 UTC for NO, NO₂, O₃, PM2.5 and the same moment for NOX, while the PM10 reading was last refreshed on 2026‑02‑10 at 22:00 UTC.

Across the pollutants the reported values show a modest spread. For PM2.5 the measurements range from 5.0 to 26.8 µg/m³ with a median of about 11.6 µg/m³; for NO₂ the range is 0.0045–0.0155 ppm and the median sits near 0.007 ppm. Ozone values vary between 0.022 and 0.054 ppm, centering on a median of 0.0335 ppm. The nitrogen oxides series are tightly clustered: NO spans 0.0022–0.005 ppm (median 0.0036 ppm) and NOX runs from 0.0095 to 0.0177 ppm (median roughly 0.0136 ppm). PM10 is represented by a single value of 107.0 µg/m³, reflecting only one recent row for that pollutant.

The dataset is relatively fresh overall, with all but the PM10 observation updated within the last two days. However, coverage is uneven: while NO, NO₂, O₃ and PM2.5 each have multiple recent rows (four to six), PM10 relies on a single entry, and the total number of rows per pollutant ranges from one to six. Consequently, city‑wide conditions may differ across neighborhoods and times, especially for pollutants with fewer observations.

Data notes

The data shown for Bakersfield reflects eight valid measurements and was Updated today, with the most recent reading recorded at 2026‑02‑11T00:00:00+00:00. This snapshot provides a current view of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
