The first factor that affects climate?

Air Masses and Winds- Areas that are closer to bodies of water tend to have a low temperature and areas further away from bodies of water tend to have a high temperature range. Some parts of Pakistan are located near the Arabian Sea. Since the sea is closer to the equator it is fairly warm. The warm air that rises from the sea is warm moisture. It sooner forms into a cloud carrying all the moisture and moves onto land like parts of Pakistan which include Karachi and Hyderabad. Eventually the moisture cools and lets of precipitation.

Latitude- Latitude affects climate depending on how close a country is to the equator. If the country is closer to the equator the temperature will be warmer and if it is farther away, it will be colder. As for Pakistan, it's latitude and longitude is about 30 N and 70 E which makes it 30 away from the equator. The sun is never more 23.5 north or south from the equator. And as the latitude of Pakistan is close to 23.5 which makes it temperature fairly warm.

For more confirmation, Canada's latitude is 60 N while Pakistan's latitude is 23 N which can prove that the farther away from the equator, the colder it is.

Ocean Currents- Warn Ocean currents hold warm water. The heat from the water escapes into the air creating warmer weather and precipitation. The Indian ocean current is one of the closest ocean currents to Pakistan. It is a warm ocean current as you can see in figure 1.0. It brings warm air and as the heat escapes into the air it gives Pakistan warmer weather and precipitation.
