Quick Answer
The best time for smoke signal visibility is typically late morning to early afternoon, around 11 am to 2 pm when the atmosphere is usually calm and the smoke rises steadily, allowing the signal to be seen from a distance.
Atmospheric Conditions for Visibility
Visibility of smoke signals greatly depends on atmospheric conditions. A calm atmosphere with minimal wind and air currents is ideal for smoke signals. In these conditions, the smoke rises steadily and remains at a consistent altitude, increasing the chances of the signal being seen from a distance. Avoid signaling during periods of high winds, heavy precipitation, or extreme temperatures.
Best Time for Visibility
Late morning to early afternoon (11 am to 2 pm) is usually the best time for smoke signal visibility. During this period, the atmosphere is typically calm, and the smoke rises steadily, allowing the signal to be seen from a distance. The angle of the sun also plays a crucial role, as a low sun angle (around 30-40 degrees) helps to maximize the visibility of the smoke signal.
Height and Angle of the Signal
To maximize visibility, the smoke signal should be at an angle of around 30-40 degrees relative to the observer’s line of sight. This is achieved by positioning the fire at a height of around 10-15 meters (33-49 feet) above the ground. At this height, the smoke rises steadily, and the signal can be seen from a considerable distance, making it an effective means of communication in survival situations.
