Can I Burn Outdoors Today? Check the Ventilation Index

The daily Smoke Control Forecast contains predictions of the Ventilation Index, a measure of atmospheric turbulence and low level winds, for 25 B.C. locations.

The burning of woody debris outdoors is only permitted when the forecast Ventilation Index is sufficient to disperse smoke. Before debris can be ignited, the Ventilation Index must be predicted to be both GOOD (55-100) this afternoon as well as FAIR or GOOD (34-100) tomorrow afternoon. Additional rules on outdoor burning are in the Ministry of Environment Open Burning Smoke Control Regulation.

The Ventilation Index ranges from 0 to 100, as summarized in this table:

Ventilation Index Ventilation Category
0 - 33 POOR
34 - 54 FAIR
55 - 100 GOOD
