I generally have the feeling that hot months are moving forward since a few years, while the summer has become more intense much earlier. When I was a kid (~20 years ago) it was normal for me in southern Germany to have enough snow in December to build snow men. In the last 10 years this has barely ever been the case. Instead, February and even March became much colder than previously. But all in all the winter shortened, in my personal perception. By now we have really dry and hot June months which I did not experience before.
