The Earth's surface and the air above it cools at night. When the sun comes up and heats up the Earth's surface it slowly heats the air above it by convection from the ground to the air. The sun also heats the air directly by radiation. This causes uneven heating of the air. The air above gets hotter quicker.
Air that is warm expands. Air that is cool contracts. Expanding air exerts more pressure on its surroundings. It needs to expand SOMEwhere. Air that is contracting (the molecules literally get closer together) 'sucks' in. Air that is expanding moves into areas where air is contracting - or from high pressure areas to low pressure areas.
Consequently - evenings are generally windier than mornings because there is a bigger temperature and therefore pressure differential from one area to the next.
Other factors such as humidity and the effect of the Earth's rotation , large water masses and geographical features (forests, mountains etc) all contribute to weather and wind patterns.
