What are two major reasons why coastal areas have a milder climate?

1. Proximity to large bodies of water: Coastal areas benefit from being near oceans or seas, which have a moderating effect on temperatures. Bodies of water are slower to heat up and cool down compared to land, which helps regulate the temperature of coastal areas throughout the year.

2. Ocean currents: Ocean currents play a significant role in shaping the climate of coastal areas. Warm ocean currents can bring milder temperatures to coastal regions, while cold currents can have the opposite effect. Additionally, ocean currents can also contribute to increased humidity in coastal areas, which can further moderate temperatures.
