During the winter season, we feel colder due to clear weather. Clear skies allow more outgoing longwave radiation (heat) from the Earth’s surface to escape into space, resulting in cooler temperatures at ground level. Without cloud cover to act as insulation, the Earth’s surface cools more rapidly, contributing to colder conditions. Additionally, clear weather often accompanies high-pressure systems, which bring dry air and colder temperatures.

In contrast, cloudy weather (option B) tends to have a moderating effect on temperatures during winter by trapping outgoing heat and reflecting some of it back to the surface. Humid weather (option C) may make the air feel colder due to increased moisture content, but it does not necessarily result in colder temperatures. Therefore, the correct answer is [A] Clear weather, as it leads to colder conditions during the winter season.
