Why do coastal regions tend to experence more mild winters than continental regions?

Coastal regions experience more mild winters than continental regions primarily due to the moderating influence of large bodies of water, such as oceans and seas. Water has a high heat capacity, meaning it retains heat longer and releases it more slowly than land. As a result, coastal areas benefit from warmer temperatures during winter, while continental regions, which are further from the ocean, experience greater temperature fluctuations and tend to be colder. Additionally, ocean currents can also affect coastal climates, contributing to milder winter temperatures.
