Excuse me, there are many waters in a place, will it affect the weather there?

Of course it matters. The more water, the more evaporation, the more moisture in the air, and of course the more rain.

It is windy in summer because the specific heat capacity of water is smaller than that of land, so the temperature of water is slower than that of land. In addition, the evaporation of water takes away a part of the heat, so your temperature is lower that summer than in places with less water around you. Low temperature leads to high air pressure, high ambient temperature leads to low air pressure, and the direction of high air pressure leads to low air pressure, thus generating wind. The windy seaside is the reason.
