It is known as The Heat Island Effect or Urban Heat Island. The main cause is the materials that are used to modify the land surfaces (asphalt roads, concrete sidewalks) and buildings contain materials store short wave radiation effectively. A secondary contributor is waste heat generated by energy usage.

Large cities often create their own microclimates due to factors like buildings, roads, and transportation systems that absorb and retain heat. Additionally, the urban heat island effect causes cities to be warmer than surrounding rural areas. These factors can make a city's climate different from the surrounding areas.
Cities located in valleys or areas surrounded by mountains are more likely to have temperature inversions. These geographical features can trap cool air near the ground, preventing it from mixing with warmer air above. Human activities, such as vehicle emissions and industrial processes, can also contribute to the formation of temperature inversions in cities.
Cities are warmer than the areas immediately around them.
Vaporized water rises because it is 100 degrees Celsius or warmer and is therefore warmer than the surrounding air and warmer air always rises above colder air.
When water changes to ice, heat is released during the process, causing the surrounding air to warm up. This is because the water molecules are losing energy as they solidify into ice.
Cities are usually warmer than the surrounding open countryside, due to heat loss from buildings, vehicles, etc.
Concrete jungles, or Urban Heat Islands, as they are known, hold the heat better. Cities, especially cities with few parks and green belts, are usually warmer than the countryside. This, however, does not affect global warming. Globally temperatures are averaged, and the cooler countryside balances out the warmer cities. Scientists measuring the temperature are always careful to make sure urban heat islands do not influence the temperature trends, which are increasing at the same rate in cities and countryside.
There are several climate differences in large cities when compared to their surrounding areas. The center of large cities is up to 10 to 20 degrees Fahrenheit warmer than the surrounding areas. A blanket of pollutants and moisture hangs over large cities which contributes to the increased temperature. Tall buildings also alter wind speeds and direction, along with amount of precipitation.

If moisture content is the same, it would be warmer.
The urban heat island effect is a warming effect. Unban means 'city'. Buildings and roads retain more heat and warm the air around them, so cities are warmer then the countryside.
