Answer:
Due to presence of ocean near it.
Explanation:
The heat capacity of water is higher than soil means that soil quickly heats up at day time and cool down at night whereas, water takes more time to heat up and cool down so that's why those areas present far from ocean observe high fluctuation in day and night temperatures due to quickly heat up and cool down as compared to those areas present near water such as coastal areas which takes more time to heat up and cool down..
