Understand the Fire Environment

  • Weather

Weather influences are the most unpredictable and the quickest to change. Weather aspects that have a direct effect on fires are wind, moisture (soil and ambient), air stability and temperature. The current weather conditions in combination with those of the last several days will also have an effect on fire behaviour.

  • Topography

Topography includes surface features such as slope, aspect and elevation (height above sea level), which can influence fire to change its behaviour as it advances through the landscape.

  • Fuels

Weather and topography can’t be altered, but fuels can be modified. The type of fuel determines the intensity of a potential fire and influences the rate at which it spreads. Veld and forest fuels are divided into two main groups: light or fast-burning fuels and heavy or slow-burning fuels. Buildings (homes, barns, sheds, commercial buildings etc) are a third fuel type.
