Why were the alarms to burn always at night?

The alarms to burn were typically set at night to minimize the risk of fire spreading uncontrollably during the day when winds and other environmental factors were more unpredictable. Nighttime also allowed for better visibility of flames against the dark sky, making it easier for firefighters to locate and respond to the fire. Additionally, fewer people were usually active outdoors at night, reducing the risk of accidental injuries or further igniting nearby structures.
