During winter, skies often appear bluer due to a combination of atmospheric conditions and the angle of sunlight. When the air is colder, it tends to hold less moisture and dust, resulting in clearer air. This clarity allows sunlight to scatter more effectively, producing a vibrant blue hue. Additionally, in the winter months, the sun is lower in the sky, enhancing the scattering effects of Rayleigh scattering, which occurs when sunlight encounters small particles in the atmosphere. As a result, the contrast between the blue sky and the often snow-covered ground becomes more striking, creating a picturesque winter landscape
