The way the Earth's axis rotation affects the seasons depends on how far away the Earth is from the sun. When one part of the Earth is tilted toward the sun then it's summer and the other part of Earth is having winter.

Explanation:
Effects of Wind
on forecasted temperatures
At night, the earth's surface cools by radiating heat off to space. The strongest cooling takes place right near the surface while temperatures at roughly 3000 feet are actually warmer than those at the surface. On a windy night, some of the warmer air aloft is mixed down towards the surface. This occurs because the winds are faster aloft than at the surface.
To visualize this, place one hand over the other about six inches apart. The bottom hand represents the air near the surface and the top hand represents the warmer wind higher up. Move the bottom hand slowly and the upper hand faster (to indicate the faster winds aloft). The faster air above and slower air below causes the air to overturn or spin (as in the picture below). This overturning motion is how warmer air from above is transported downward on windy nights.
There are changes in temperature daily. An impact of South Indian high pressure cell and south Atlantic high pressure cell on movement of cyclones will lead to a lowering of warming air and dry conditions for almost all year round.
<h3>What is the impact of South Indian high pressure cell?</h3>
The South Atlantic, South Indian and Kalahari anticyclones are known to influence the climate of South Africa all year round
They tend to decrease the descending movement of warming air and dry conditions all year round and they also take place sue to the positions that they occupy is always changing.
This makes us to have changing seasonal climate and changing weather conditions all year round.
