Duncan Wildfire Smoke Map
Follow modelled wildfire smoke around Duncan and Vancouver Island with FireRadar's hourly ECCC FireWork forecast guidance.
How to read smoke around Duncan
Duncan is a central Cowichan Valley service centre surrounded by forested hills, rural properties, agricultural land, recreation areas, and the Island Highway corridor. Wildfires on Vancouver Island can affect local roads, nearby communities, forestry and recreation activity, and smoke even when an incident is outside the urban area. Smoke affecting this area can come from nearby incidents or be transported over much longer distances, while wind, terrain, frontal changes, inversions, and local lake or coastal circulations can change what reaches the surface. FireRadar therefore presents ECCC FireWork as forecast guidance rather than a ground-level measurement, and the model should be compared with current observations and official health guidance when conditions matter.
Forecast, not a measurement
FireWork estimates near-surface PM2.5 attributable to wildfire smoke. It can differ from actual conditions around Duncan 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 Duncan. 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.
