Dubai, October 21, 2026: daily mean PM2.5 35 µg/m³ (5 sensors), level “Moderate” — as in the Atmy Data Hub. Now (22:00 local time): 37.4 µg/m³. Open methodology and data in JSON: Methodology and data sources · JSON
Right now in Dubai, PM2.5 averages 37.4 µg/m³ — “unhealthy for sensitive groups” on the US EPA scale (approximate, from hourly readings). Mean of 5 sensors on the Atmy network, readings from 21:47–21:47 local time (17:47–17:47 UTC), summary prepared at 22:00 local time. Median: 40.0 µg/m³; range across sensors: 30.0–42.3 µg/m³.
In Dubai the air is unhealthy for sensitive groups right now (approximate, US EPA scale). From 09:00 to 22:00 local time the city mean PM2.5 rose from 28.8 to 37.4 µg/m³. The highest hour was 14:00 with 122.2 µg/m³.
Light wind (2 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion).
Weather now: clear, 31°C, wind 2 m/s, humidity 69%. No major change in the wind is expected in the coming hours.

Daily mean PM2.5 on October 21, 2026 (00:00–24:00 UTC): 35 µg/m³ from 5 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 1 of 1 cities in United Arab Emirates and No. 10 of 297 worldwide, from the most polluted.
Right now in Dubai, PM2.5 averages 37.4 µg/m³ — “unhealthy for sensitive groups” on the US EPA scale (approximate, from hourly readings). Mean of 5 sensors on the Atmy network, readings from 21:47–21:47 local time (17:47–17:47 UTC), summary prepared at 22:00 local time. Median: 40.0 µg/m³; range across sensors: 30.0–42.3 µg/m³.
The current level is “unhealthy for sensitive groups” (US EPA scale, approximate). Children, older adults and people with heart or lung disease should reduce prolonged or heavy exertion outdoors. This is the standard guidance of the scale, not medical advice.
Highest current reading: 42.3 µg/m³ (GEMS SRI Padel Court). Lowest: 30.0 µg/m³ (Dubai Motor City). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
Over the last 160 days with data, the mean daily PM2.5 in Dubai was 37.1 µg/m³ — 7.4 times the WHO annual guideline (5 µg/m³). Over the last 30 days: 42.6 µg/m³. From Atmy's archive of daily city means.
In Atmy's daily archive, the cleanest month of the last year was April 2026: 25.1 µg/m³ on average.
The most polluted month of the last year was September 2026: 45.5 µg/m³ on average.
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
