If there is a low pressure area or storm in the region the winds will blow day or night.

Is it windier during the day or night?

Why is it more windy in the afternoon?
The drying power of the air will tend to be highest in the afternoon. Items that need to air dry will tend to dry fastest in the afternoon, especially if exposed to solar energy. Once the sun rises and mixes out the cool and stable air right at the surface, wind speeds can pick up significantly.
Why does it get windy at night?
In the morning, when sunlight returns and begins to warm the surface layer, the wind from above gradually builds downward and returns to the surface. At night, winds above the surface layer often increase in strength because its energy is not dissipated by contact with the ground.
Why is it so windy during the day?
During the day, the sun unevenly heats up the air. … As air warms, it weighs less and rises, creating an area of low pressure behind it. As air cools, it weighs more and sinks, creating an area of high pressure. These differences in areas of low versus high pressure are what create the wind.
Is wind worse higher up?
“The winds are stronger higher up,” he said, “but on a typical summer day, with no storm systems, it is not that big of an issue. … “Generally, the higher you go, you lose what is called the friction layer,” where friction with the surface of the earth itself slows the wind somewhat, Mr. Searles explained.

Why is March windy?
So why is March so windy? The answer lies in the fact that March is a month of seasonal transition.
