The coastal areas experience less variation in temperature as compared to land. The reason is that the heating or cooling capacity of water is much less as compared to land. It means that water takes more time to get hot or cold then land. Therefore areas near sea or ocean have more moderate temperature in the day time and less cooler at night. In the day time, as the water takes comparatively more time to get heated, so areas around water (coastal areas) remains moderate. Similarly, at night water takes more time to get cooled hence areas around ocean do not show much variation in temperature.

Introduction:
The coastal areas of India experience less contrast in temperature due to various factors. These factors include the proximity to the ocean, the influence of sea breezes, and the presence of water bodies. This results in a more moderate and stable climate in coastal regions compared to inland areas.
Proximity to the ocean:
Coastal areas are in close proximity to the ocean, which acts as a natural temperature regulator. The temperature of the ocean water changes very slowly, and it has a high heat capacity. As a result, the coastal regions experience a relatively stable temperature throughout the year. The ocean prevents extreme temperature fluctuations as it absorbs heat during the day and releases it at night, moderating the temperature.
Influence of sea breezes:
Coastal areas are often influenced by sea breezes, which further contribute to the less contrasting temperature. During the day, when the land heats up faster than the ocean, the warm air rises over the land and creates a low-pressure system. This draws in cool air from the ocean, resulting in a sea breeze. The sea breeze brings cooler air from the ocean, reducing the temperature in coastal areas. Similarly, during the night, when the land cools down faster, the air over the land becomes cooler and denser, creating a high-pressure system. This causes the air to flow from land to sea, resulting in a land breeze.
Presence of water bodies:
Coastal areas are often characterized by the presence of water bodies such as lakes, rivers, and lagoons. These water bodies have a moderating effect on the temperature by absorbing and releasing heat slowly. They act as heat sinks, regulating the temperature in their vicinity. Additionally, water bodies also contribute to the humidity levels in coastal areas, which further affects the temperature. Higher humidity levels tend to make the temperature feel warmer due to reduced evaporation of sweat from the skin.
Conclusion:
The coastal areas of India experience less contrast in temperature due to the proximity to the ocean, the influence of sea breezes, and the presence of water bodies. These factors contribute to a more moderate and stable climate in coastal regions compared to inland areas. The ocean acts as a natural temperature regulator, sea breezes bring cool air from the ocean, and water bodies absorb and release heat slowly. Understanding these factors helps explain why the coastal areas of India have a relatively consistent temperature throughout the year.
