Temperature is never stable. It goes on changing with time and place. 

Many factors affect the temperature which are as follows :

1. Distance from the Equator: On the equator the sun rays are straight. So, the heat is more and as a result the temperature is more. As we move towards polar regions the sun rays become .slant and as a result these regions are cold and the temperature is very less.

2. Height from Sea Level: The place which is higher than the sea level has less temperature. The reason is that when we near the sea coast the air is dense but as we move up the air becomes thin. So, the high places have low temperature, e.g. Shimla is at a more height than Chandigarh. So, the temperature of Shimla is less than the temperature of Chandigarh.

3. Distance from Sea: In comparison to land, the water beats up early. So, the places which are near the sea the temperature is neither more nor less. But the places which are away from the sea, there the temperature is less in winter and more in summer, e.g. Mumbai has stable temperature because of its closeness to sea. Whereas, Amritsar is very far away from sea and as a result there is much difference in summer and winter temperature.

4. Sea Waves: The sea waves are of two types hot and cold. Where the hot waves flow the temperature there increases and where the cold waves flow the temperature there decreases.

5. Winds: The winds that come from sea are full of water vapours and produce rainfall. As a result the temperature becomes less. On the other hand the winds coming from dry areas increase the temperature of places which come in their contact.

6. Direction of Mountains: The mountains which are horizontal to the direction of winds they cannot stop the watery winds and as a result no rainfall happens there. But the areas with vertical mountains to the wind direction can stop the winds and cause rainfall.

7. Slope of Mountains: The mountain’s slope facing the sun had more temperature. While the other side of the mountains has no temperature.

8. Types of Soil: The sandy soil heats up quicker than the clay. So, in the arid areas the temperature in the daytime, is more. But in the nighttime, it is less.

9. Clouds and Rains: The places where there are more clouds and rains have less temperature because clouds stop the sunlight from reaching the earth directly. As a result, the temperature is less. Similarly, the rains also decrease the temperature.
