Question

Why those places which are nearby river having cool air

Answer 1

because of the sea and land breeze

Answer 2

Because of its high specific heat, it takes longer far water to get heated up or to get cooled. During summer days, the land near the sea gets heated up quickly but the sea water remains cool and thus, cool breeze blowing from the sea reduces the heat in the adjoining land area. The reverse happens in winter. The land gets cooled quickly but the sea water remains warm and thus, the land gets warm breeze from the sea. But the land farther inside does not have this advantage. This account for the difference in the climatic conditions.
