Yes, the Sun's angle at noon changes significantly throughout the year. This is because the Earth's axis is tilted at an angle of about 23.5 degrees with respect to its orbit around the Sun. This means that as the Earth orbits around the Sun, different parts of the Earth receive different amounts of sunlight depending on where they are in relation to the tilt of the axis. This results in the Sun's angle at noon being higher in the summer and lower in the winter in most parts of the world.
