Prescribed fires can be conducted year-round anytime land or habitat management objectives can be safely achieved.
Historically, fires occurred throughout the year in North America, although for most locations, fire was more prevalent during specific seasons. Trying to burn during these historic fire seasons can be problematic for some locations because of safely concerns and limited days when weather conditions fall within prescription. However, burning outside of the historic fire season does not preclude the ability to meet management objectives in most cases.
For more information about season of burn or the time of year to conduct burns, see The Best Time of Year to Conduct Prescribed Burns.
