AAFC Canadian Drought Monitor · monthly dryness context

Canada Drought Monitor & Wildfire Conditions

Drought can shape the broader moisture and fuel environment in which wildfire seasons develop, but drought is not the same thing as daily fire danger and does not predict where a wildfire will ignite. FireRadar links Canada's official Canadian Drought Monitor with current wildfire, Fire Weather Index, smoke, and AQHI products so those signals can be compared without being collapsed into one unsupported risk score.

Source cadence

National drought conditions are assessed monthly using multiple indicators and expert interpretation.

FireRadar links to the current official assessment rather than estimating a drought class between AAFC releases. Historic monthly maps and change analysis remain available from the official source.

How drought relates to wildfire conditions in Canada

The Canadian Drought Monitor combines precipitation, temperature, streamflow, vegetation and drought indices with expert interpretation. Conditions are published from D0 (Abnormally Dry) through D4 (Exceptional Drought). Monthly drought classification is useful for longer-term context, while current fire behaviour still depends on fuels, recent weather, wind, ignitions, topography, suppression and other local factors.

Drought

Longer-term moisture deficit and dryness context from the monthly AAFC national assessment.

Fire Weather Index

Daily weather-based fire-potential guidance from NRCan CWFIS. It can change much faster than monthly drought status.

Active wildfires

Actual current incident records from responsible wildfire authorities. These remain separate from both drought and forecast products.
