Courtenay Annual Report 2025 draft

Air quality monitoring and winter smoke patterns Air quality data for Courtenay continues to show gradual improvement, with average annual levels of fine particulate matter declining since 2017. However, monitoring confirms that winter evenings and early mornings remain a concern, with short-term increases linked to wood burning appliances and seasonal conditions. Data from the provincial monitoring station at Courtenay Elementary School, combined with readings from 20 local PurpleAir monitors, provides a clearer picture of air quality patterns across the community. While wildfire smoke events result in elevated readings across all locations, winter conditions show greater variation, with higher concentrations typically observed in older neighbourhoods. This expanded monitoring network supports regional collaboration and helps residents access real-time air quality information. Findings are informing public education and outreach, including encouraging reduced wood-burning and promoting available rebates for home heating upgrades. courtenay.ca/air-quality
