How do eastern and western hemisphere seasons related?

Answer 1

Assuming you are on the same side of the equator, they are essentially the same. North of the equator, summer in Kansas is the same as summer in Belgium. But summer in Kansas and Belgium is Winter in Australia (South of the equator).

Answer 2

The seasons in the Eastern and Western Hemispheres are opposite of each other. For example, when it is summer in the Northern Hemisphere (Western Hemisphere), it is winter in the Southern Hemisphere (Eastern Hemisphere), and vice versa. This is because of the tilt of the Earth's axis as it orbits the Sun.
