There are different kinds of weather:  sunny, rainy, snowy, windy. My favorite weather - warm and sunny, when the  breeze sways the branches of trees. In the summer it is often heatwave and after that it is usually downpour and I like it. Also I like photographing bolts of lightning. After the shower there is clean, fresh air and scorching sun ceases to torment people.

I do not like winter and snowy weather, because it's cold. Often there are storms, blizzards, gales which I hate.  The sky is overcast and sun rays can get through the clouds very rarely. The nastiest weather –it is sleet. Shoes, clothes become wet and at this time it is very easy to get sick.
