Canada Wildfire Smoke Forecast and Live Air Quality

Hourly fine particulate matter (PM_2.5) at 271 Canadian monitoring stations plus 560 PurpleAir community sensors, compared against the FireSmoke and FireWork smoke forecasts.

National outlookAcross Canada's monitored network, 27 stations are reporting elevated smoke levels, with 10 in the Unhealthy range and Vernon Science Centre, British Columbia, reaching Very Unhealthy at 129 µg/m³. Several British Columbia communities face high AQHI risk, including Kamloops and North Okanagan at 10+. In the North, smoke models estimate Fort Simpson, Northwest Territories, is experiencing rising levels forecast to reach 271 µg/m³, entering the Hazardous range. Over the next 48 hours, models predict the highest smoke concentrations in British Columbia, with Skookumchuck Farstad Way, Kamloops Federal Building, and Cranbrook Muriel Baxter all forecast to exceed 500 µg/m³.

PM_2.5 observations and smoke forecasts (µg/m³)

Observations and NowCast are total PM_2.5 — wildfire smoke plus every other source — as regulatory monitors measure it, and FireWork models that same total. FireSmoke is a smoke-dispersion model: it estimates the wildfire contribution only, so it reads lower than the monitors whenever other sources matter. The map's optional plume layer is likewise fires-only.

Stated times are local to the selected station and mark the end of each measurement hour, as provincial displays do. FireSmoke is UBC's BlueSky dispersion model; FireWork is ECCC's operational chemistry model. NowCast is the US EPA's smoke-responsive weighted average of recent hours; the shaded bands are US EPA AQI category thresholds (24-h basis, 2024 revision), which apply to NowCast — not to single hourly readings. The dashed line marks now; forecasts extend beyond it.
