During dry season (July - November), wildland fire hazard is extremely high and can become acute during periods of high winds. Conditions that can increase the likelihood of a wildland fire are:

• High winds: Santa Ana winds create flash point conditions
• Weather: dry, low humidity
• Available fuels: despite 2007 firestorm, unburnt vegetation at a record high
• Drought conditions
• Topography shapes fire's path
• Hazard intensifies in summer/fall
• Carlsbad can experience the same fire hazard conditions as east San Diego county despite proximity to the coast
  

Most Wildland fires can be linked to human causes. However, awareness and action can mitigate human causes.

• Ensure vehicles are in proper repair.
• Avoid using spark/heat generating equipment in/near dry brush areas.
• Establish defensible boundaries between home/work areas and dry brush areas.
• Schedule spark/heat generating work during cooler parts of the day.
• Pre-inspect grass areas before mowing to remove spark producing debris.
• Ensure portable firefighting equipment is operational.
• Avoid parking vehicles roadside or in dry brush areas.
• Dispose of flammables (charcoal, etc.) properly.
• Clear off debris from the roof and gutters, screen vents.
• Discuss hazard and actions with staff and family to broaden awareness.
• Consider purchasing pool pumps or protective additives, like gel.
• Plan escape routes.
• Evacuate early or when directed to do so.
