Katabatic winds occur at what time of day?

Katabatic winds are a type of wind that occurs when cold, dense air descends from high elevations, typically during the nighttime hours. At night, the ground cools rapidly, and the air close to the surface can become cooler and heavier than the surrounding air. This colder, denser air then flows downhill under the influence of gravity, creating katabatic winds.

The strongest instances of katabatic winds generally happen in the early hours of the night as the temperature difference between the cooled ground and the surrounding air becomes most pronounced. Consequently, the presence of katabatic winds is closely linked to nighttime conditions, making this time of day a defining feature of their occurrence.
