Graphical Summer

This post is for the nerdy, data-visualization enthusiasts out there. Just as my summer so far has been varied in geography, it has been varied in temperature and humidity. First, I present a simple plot of average temperature and humidity as a function of the day, the starting at graduation and ending yesterday. The discontinuities indicate where I was on the train for an extended period of time. I experienced a range of average temperatures from 49 to 90 F, and a range of humidities from 8 to 93%.


The second graph plots the humidity against the temperature to show the different regimes of U.S. summer that I experienced. I clustered the destinations by region and time, so that the legend reads in chronological order. Note that the lower the humidity, the wider the spread between high and low temperatures (for example, in Albuquerque and Tucson). The highest temperature I experienced was in Tucson, at 105 F. I do not know the lowest low because I slept inside, and I never wondered how cold it was. Perhaps the most noticeable weather event of the entire summer was when the average temperature in Milwaukee rose by 22 F in two days. You can see this in the two red line segments that traverse the "Midwest" cluster from top left to bottom right. I am now at the bottom right of the "Texas" cluster, reveling in the heat and mild (compared to Houston) humidity.
