Rain, fog, and high winds are conditions that can significantly affect the safety and stability of drone operations. Rain can lead to moisture accumulation in electronic components, which might result in malfunctions or reduced visibility for the drone's cameras and sensors. Fog can severely limit visibility, making it difficult for the operator to see the drone or for the drone's sensors to detect obstacles. High winds can cause the drone to be difficult to control, leading to the potential for loss of aircraft and unsafe flight conditions.

In contrast, sunny days offer good visibility and stable conditions that are generally favorable for flying drones. Clear and calm conditions provide the best environment for flight safety and precise navigation. While cold temperatures may present some challenges, they are not inherently dangerous like the combination of rain, fog, and high winds, which can create immediate and severe operational hazards. Therefore, avoiding rain, fog, and high winds is essential for ensuring safe drone operations.
