概要

 Phoenix's air quality today stands at a moderate level, with an AQI around 49 to 74, posing minimal risk for most but caution for those with respiratory issues.[1][2][3] This places it in the acceptable range, where sensitive individuals might notice effects during prolonged outdoor activity.[3]

Recent data from monitoring stations like West Phoenix show PM2.5 at about 16 µg/m³ and PM10 at 28 µg/m³, alongside low levels of NO2 (21 ppb), CO (502 ppb), SO2 (1 ppb), and O3 (11 ppb).[2] In the last 24 hours leading into today, AQI peaked at 61 around midday yesterday but dipped to 21 in the afternoon, reflecting typical diurnal swings—higher at noon (average 64) and lower evenings (around 34).[1]

February 2026 trends reveal improvement: 60% of the month's 41 days so far met WHO safe limits, with today's 49 ranking as the second-highest on this date over five years, yet still "Good."[1] Daytime peaks often hit 12 PM due to traffic and sun-driven ozone formation, while nights cool and trap fewer pollutants. Compared to January's highs near 72, February breathes easier, aided by mild 20°C partly cloudy skies and 6 km/h winds dispersing haze.[1][2]

Phoenix's bowl-shaped valley amplifies winter inversions, trapping dust and emissions, as seen in past spikes from fireworks.[4] Yet, 63% of early 2026 days stayed safe overall, underscoring moderate health risks mainly for heart or lung patients.[1] Outdoor enthusiasts can enjoy hikes, but asthmatics should limit exertion.[3]

For real-time updates, check Maricopa County monitors—today's moderate rating means clear skies for Valentine's Day revelry without major worry.[1][3][6]
