Air quality today

The air quality in Whistler today is classified as Good. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 0.0028 µg/m³ based on nine valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Whistler air‑quality feed pulls data from two monitoring sites that together generate ten recent rows of observations. All eight measured variables are represented: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter in the 1 µm, 2.5 µm and 10 µm size fractions (PM1, PM2.5, PM10), relative humidity and temperature. For most pollutants the latest reading comes from 2026‑02‑10 22:00 UTC, showing a very fresh snapshot across the board. The exception is PM10, whose only available value dates back to 2025‑01‑13 23:00 UTC, so that metric is considerably older than the rest.

The numeric spread is narrow for several constituents. NO, NO2 and O3 each have a single recorded value – 0.0004 ppm, 0.001 ppm and 0.03 ppm respectively – all measured at Whistler Meadow Park on the same recent timestamp. PM2.5 also shows a single figure of 0.0 µg/m³ from the same location and time. PM1 is likewise reported as 0.0 µg/m³, but this reading comes from the broader “Whistler” site rather than the Meadow Park sensor. In contrast, PM10 registers a solitary value of 2.23795834928751 µg/m³ from the older 2025 record, highlighting an uneven temporal coverage across particle sizes.

Relative humidity and temperature are both captured at one point in time: 64.11929171880085 % and 9.532208319505056 °C respectively, each measured on 2026‑02‑10 22:00 UTC at the Whistler site. Because the dataset consists of a limited number of rows and only two stations, it provides a snapshot rather than a continuous picture; conditions can differ across neighborhoods and over time, especially for pollutants like PM10 where recent data are lacking.

Data notes

The data shown reflects nine valid measurements and was 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 air quality in Whistler, British Columbia, but conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
