Ground level concentration of particulate matter 2.5 microns and smaller (PM2.5) in units of micrograms per meter cubed (µg/m3).
The BlueSky Canada smoke forecast is our current best estimate of when and where wildfire smoke events may occur over the next two days. The map may not agree exactly with local smoke concentrations and timing, and should be used with care. For additional information please consult the FAQ.

This BlueSky Canada smoke forecast is considered experimental because it is produced by a modeling system that is an ongoing research project and subject to uncertainties in fire data and emissions, weather forecasts, and smoke dispersion. The system uses satellite detections to locate fires; if cloud cover or smoke obscures the detection of fires from space, the resulting emissions from these fires will not be included in the smoke forecast.
NOTE: This forecast does not include smoke from sources that are outside the boundaries of the forecast domain. The BlueSky framework currently does not have a mechanism to transport smoke into the model domain from external sources. Please use the Canada-wide forecast to evaluate whether long-range smoke transport may affect your region.

If you have a local event not currently captured in the BlueSky smoke forecast, consider using our Playground ad hoc smoke modelling tool. Playground allows you to create emissions scenarios for wildfires, prescribed burns and pile burns, then model and view the resulting smoke dispersion.
View the Rapid Response Smoke Forecasting with Playground tutorial for more information on how to use Playground.
