Air quality today

The air quality in Winnipeg today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 0.0 µg/m³ based on four valid observations collected via OpenAQ.

No other pollutants reached reporting thresholds, and the limited dataset reflects consistent conditions across the measurement sites. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Winnipeg includes six measured pollutants – PM1, PM2.5, PM10, relative humidity, temperature and UM003 (particle count). The dataset comprises eleven rows of observations drawn from two monitoring stations. For five of the pollutants the most recent reading was recorded on 2026-02-10 at 22:00 UTC, while the PM10 value lacks a timestamp and is marked as unknown.

Across the available data the concentration ranges are modest for the fine‑particle metrics: PM1 varies from 0.0 to 1.38 µg/m³ with a median of about 0.69 µg/m³, and PM2.5 spans 0.0 to 30.78 µg/m³ with a median near 15.39 µg/m³. The single PM10 entry is fixed at 3.91 µg/m³, reflecting the limited coverage for that metric. Relative humidity measurements show a spread from roughly 52.6 % to 84.4 %, centering around 68.5 %. Temperature readings range between –1.69 °C and 23.82 °C, with a median of 11.07 °C, indicating the dataset captures both cold snaps and warmer periods within the same day. Particle counts (UM003) are reported in the range of 51.14 to 306.52 particles/cm³, median 178.83.

Two practical points emerge from these numbers. First, five pollutants have fresh data updated within three days, but PM10 is effectively missing recent information, so city‑wide assessments for that metric are incomplete. Second, the dataset’s breadth varies: while humidity, temperature and UM003 have full coverage across both stations, fine‑particle data rely on only two rows each, limiting spatial resolution. Consequently, conditions can differ noticeably across neighbourhoods and times, especially for pollutants with sparse or outdated records.

Data notes

The data shown reflects four valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of Winnipeg’s air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
