Real-time air-quality monitoring for Boucherville shows conditions currently within the good range, but forecasts point to a measurable deterioration over the coming days that will be relevant for residents planning outdoor activities.
Current readings and short-term outlook
At the time of the latest report, the Boucherville monitoring station registered an AQI of 17 (US scale), classified as good. Historic reporting around mid-afternoon on July 17 showed an AQI of 22 during the 15:00–16:00 hour. The IQAir summary notes that the PM2.5 concentration currently meets the WHO annual PM2.5 guideline.
"PM2.5 concentration currently meets the WHO annual PM2.5 guideline."
However, the hourly and daily forecast provided alongside the measurements indicates a rise in particulate matter through the weekend. The listed daily AQI forecast values for Boucherville are:
- Today: AQI forecast ~ 23
- Saturday: AQI forecast ~ 41
- Sunday: AQI forecast ~ 70
What those numbers mean for residents
An AQI in the range of 0–50 is considered good to moderate, while values above 50 begin to affect sensitive groups. The forecasted shift toward an AQI near 70 on Sunday moves into the lower end of the unhealthy for sensitive groups band. That has practical consequences for Montreal-area municipalities such as Boucherville, where outdoor recreation is common:
- People with respiratory conditions, older adults and young children should consider limiting prolonged or heavy exertion outdoors if the AQI approaches or exceeds 70.
- General population impacts are likely to be minimal while the AQI remains below 50, but those planning longer outdoor events should monitor updates.
Local context and monitoring
Boucherville's real-time station is the sole local reporting point listed in the summary, ranked with an AQI of 17. The IQAir data set also places other Canadian cities on a national ranking list; while those cities include locations with substantially higher readings, Boucherville's current readings remain comparatively low.

Advice for residents and public services
Local public-health and parks officials typically monitor short-term AQI forecasts when scheduling outdoor programming or issuing guidance. With the weekend forecast indicating a rise, community services that host outdoor events should keep an eye on updates from provincial and municipal air-quality sources and consider contingency plans for activities involving vulnerable participants.
Residents can check real-time readings and hourly forecasts through publicly available monitoring platforms to make informed decisions about outdoor exercise and events. For most people in Boucherville the current readings indicate no immediate concern, but the weekend trend merits attention for those most sensitive to air pollution.
