Hourly Temp Frequencies
Posted: 28 Jun 2021 05:32 AM
Temperatures were pleasant this past weekend after some very warm conditions that dominated the
previous weeks of June. The featured chart presents a histogram of hourly temperature observations
from the Des Moines airport. Values are analyzed by week of the year and binned into temperature
ranges. The chart's legend presents the overall frequencies for the chosen bins. It is interesting to
note that having temperatures over 90 degrees is about as frequent as having temperatures below 0
degrees! The chart nicely illustrates the annual progression of the seasons with sub freezing
temperatures departing for the warm half of the year and making a quick return in October. July
clearly shows up with the highest frequencies of the warmest temperatures, but the present forecast
for the start of July does not look exceptionally hot.
