Our recent stretch of weather has seen very comfortable dew point temperatures in the 60s. The featured graph is a climatology of dew point observations from the Des Moines Airport. The five lines shown represent the lower (0) and upper bound (100) of 1 PM observed dew points along with the 25th and 75th percentile and also the median value (50). The months of July and August are highlighted for their rather consistent daily values due in part to increased plant transpiration.
