How to read Henderson 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 Mccarran Intl Ap, 20.9 km from the centre of Henderson. 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. Henderson sees about 131.3 days a year at or above 90°F and about 11.2 days with a tenth of an inch of precipitation or more.
