Air quality today

The air quality in Kawartha Lakes today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 9.62 µg/m³ based on nine valid observations reported through OpenAQ.

This assessment reflects the current conditions without additional commentary. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Kawartha Lakes air‑quality feed currently draws from two monitoring sites that together provide ten recent data rows. All five measured pollutants are represented: fine particles (PM1), fine particulate matter (PM2.5), relative humidity, temperature and particle count (UM003). Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, so the dataset is uniformly fresh across the board.

For PM1 the values span from a low of about 5.36 µg/m³ to a high of roughly 9.97 µg/m³, with a median near 7.67 µg/m³ and the central 80 % of observations falling between 5.82 and 9.51 µg/m³. PM2.5 shows a broader spread, ranging from 9.62 to 19.01 µg/m³; the median is 14.32 µg/m³ and the 10th‑90th percentile band runs from 10.56 to 18.07 µg/m³. Relative humidity measurements vary between 46.31 % and 57.20 %, centering on a median of 51.76 % with most values clustered between 47.40 % and 56.11 %. Temperature records cover sub‑zero to mild summer conditions, from ‑0.18 °C up to 7.15 °C; the middle value is 3.48 °C and typical readings lie between 0.56 °C and 6.41 °C. Particle concentration (UM003) is tightly grouped, ranging only from 458.67 to 468.75 particles/cm³, with a median of 463.71 and the bulk of data between 459.68 and 467.74 particles/cm³.

Because both sites report at the same recent timestamp, there is no lag in any pollutant’s coverage, but the limited number of stations means spatial variation within Kawartha Lakes cannot be captured fully. The dataset therefore offers a concise snapshot of current conditions across the two locations rather than a city‑wide map of air quality.

Data notes

The data shown reflects nine valid measurements and was updated within three days, with the most recent refresh recorded at 2026‑02‑10 22:00 UTC. This snapshot provides a current view of air quality across Kawartha Lakes, but conditions can differ by specific neighbourhoods and times of day, so local variations may not be captured in these aggregate figures.
