In short, because of the axial tilt of the earth. In May - July, the northern hemisphere is tilted more towards the sun and gets more sunlight at a more direct angle. The reverse is true for the Southern Hemisphere. In November - January, the situation is reversed; the southern hemisphere gets more direct sunlight.
Because Earths axis is tilted.
In the southern hemisphere, September 1st marks the beginning of spring because the seasons are opposite to those in the northern hemisphere due to the tilt of the Earth on its axis. This means that while the northern hemisphere experiences spring in March, the southern hemisphere experiences it in September.
Because the Earth is tilted on its axis, so when the Northern Hemisphere is tilted toward the Sun (Summer, in the North) the Southern Hemisphere is tilted away from the Sun (Winter, in the South) and vice versa.
The day lengths in the southern hemisphere begin to increase between the Winter Solstice and the Vernal Equinox, same as in the Northern Hemisphere, but the time for the seasons is reversed. Winter solstice in the southern hemisphere falls on June 21 or 22 each year, and the vernal equinox is around 21 or 22 September.
When Earth is closer to the Sun, it is in winter in the Northern Hemisphere and summer in the Southern Hemisphere. The distance between Earth and the Sun (known as Earth's orbital distance) doesn't significantly affect the seasons; the tilt of Earth's axis is the primary factor that determines the seasons.
Because Earths axis is tilted.
It does not. Seasons are caused by the tilt of the earth on its axis. When that hemisphere is tilted toward the sun there will be summer. Away-- winter.
The seasons are reversed. When it is spring or summer in the northern hemisphere, it is the autumn (fall) or the winter in Australia. This is caused by the northern part of the world being tipped the opposite way (towards or away) from the sun to Australia. The seasons in Australia and other countries in the Southern Hemisphere are reversed from those in the Northern Hemisphere. When it is summer in the Southern Hemisphere, it is winter in the Northern Hemisphere, and so forth. For example, the Australian summer starts in December, while winter begins in July.
Countries in the Southern Hemisphere, such as Australia, New Zealand, South Africa, and Argentina, have opposite seasons compared to countries in the Northern Hemisphere. This is due to the tilt of the Earth's axis, which causes the seasons to be reversed in the two hemispheres. For example, when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere.

The seasons are reversed, AND the flow of water is reversed. When flushing a toilet in the northern hemisphere, the water goes down clockwise. When flushing a toilet in the southern hemisphere, the water goes down counterclockwise.
The hemisphere you are in (northern or southern) has an effect on when you experience the seasons. At points in the earth's orbit it is either the southern or northern hemisphere that is tilted further towards the sun. This makes that hemisphere warmer, experiencing summer while the other colder and experiences winter. Then six months later, things are reversed.
reversed
It is winter in the northern hemisphere when it tilts away from the sun, and summer in the southern hemisphere when it tilts towards the sun. It is this tilting that creates the seasons.
the seasons are usaully switched so if its summer in the northern its winter in the southern
Seasons in the northern hemisphere occur at opposite times to those in the southern hemisphere. For example, when it is winter in the southern hemisphere, it is summer in the northern hemisphere.
The seasons are not reversed in Australia. They still follow the same order - summer, autumn, winter and spring. The difference is that, when it is summer in Australia it is winter in the northern hemisphere, and vice versa. This is because of the position of the sun in relation to the Earth. To put it in the simplest terms, because the Earth is tilted on its axis, during the southern hemisphere's summer, it is closer to the sun than the northern hemisphere is, so receives more heat. This is reversed during the northern hemisphere's summer.
