The wind does indeed tend to calm down at night. This is because the surface near the ground cools down faster than the air above the surface. This means the air closer to Earth is more dense and cool which makes it slower and calmer. Above the surface, the wind is still blowing hard. During the daytime, when the Sun warms up the surface again, the air gets warmer and faster and the relationship is reversed! Reply
