Do Commercial Drones Fly When Cloudy Weather? Commercial drones can fly in cloudy weather, but their ability to do so depends on the specific conditions and regulations in place. Cloud cover can reduce visibility and interfere with a drone’s line-of-sight, which is often a requirement for operation in many regions. If the cloud cover is too thick or the weather conditions include rain, fog, or strong winds, it can compromise the safety and stability of the drone, making flight more risky.
