How to read Aurora climate normals
What a climate normal is, and what it is not.
A normal is the average of thirty years of daily observations at one station — here Denver-Stapleton, 5.4 km from the centre of Aurora. It describes a typical year, so any single year will run warmer, cooler, wetter or drier. Readings taken at an airport on the edge of town usually sit a degree or two below a dense downtown on summer nights. Aurora sees about 30.6 days a year at or above 90°F and about 39.2 days with a tenth of an inch of precipitation or more.
