Greater Sudbury Wildfire Smoke Map
Track hourly wildfire-smoke forecast guidance around Greater Sudbury and Northeastern Ontario with FireRadar's FireWork map.
How to read smoke around Greater Sudbury
Greater Sudbury sits within a large forested region where smoke can come from nearby Northeastern Ontario incidents or travel from Northwestern Ontario, Quebec, Manitoba, and farther away. Lakes, exposed bedrock, forested terrain, and shifting regional winds can create local variation that a broad forecast plume cannot resolve, so current observations remain important for health decisions.
Forecast, not a measurement
FireWork estimates near-surface PM2.5 attributable to wildfire smoke. It can differ from actual conditions around Greater Sudbury because emissions, wind, terrain, mixing, precipitation, and model timing change. Use current AQHI observations and local health advisories when conditions matter to health.
A focused starting view, not a clipped dataset
This page starts the national FireRadar layer around Greater Sudbury. The underlying FireWork smoke field is not clipped to municipal boundaries, so nearby conditions remain visible as you pan or zoom. FireRadar does not infer a uniform value inside a city boundary.
Health and safety limitation
FireRadar is an informational environmental map. Follow Environment and Climate Change Canada, provincial health agencies, local public-health guidance, and emergency authorities for health or safety decisions. This page does not diagnose exposure, determine whether outdoor activity is safe, or predict individual health effects.
