At What Temperature Does Wood Ignite?

The minimum temperature needed to ignite wood is 180 degrees Celsius or 356 degrees Fahrenheit. The amount of time of exposure varies due to the type of wood. Long-leaf wood has the fastest ignition time at this temperature, taking about 14 minutes to ignite.

For a wood ignition time of less than one minute, the wood must be heated to a temperature of 430 degrees Celsius or 806 degrees Fahrenheit. According to the U.S. Department of Agriculture, studies on wood ignition conclude that there is not a fixed temperature for ignition, and the moment of ignition largely depends on the amount of exposure time, the density of the wood and the type of wood.
