What should sailors look for in cloud formations?

Sailors should focus on specific clouds that indicate weather because certain cloud types are closely associated with particular weather conditions. For instance, cumulonimbus clouds often signify thunderstorms, while stratus clouds may indicate overcast or light drizzle. Knowledge of these cloud formations allows sailors to better anticipate changes in the weather, which is critical for planning safe voyages and avoiding hazardous conditions.

While aspects like the height of clouds, cloud color variations, and cloud movement direction may provide additional information about weather patterns, they do not offer as direct insight into specific weather phenomena as recognizing particular types of clouds. Understanding these specific cloud formations empowers sailors to make informed decisions based on the predicted weather conditions associated with them.
