How to read Baltimore 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 Baltimore-Washington Intl Ap, 3.1 km from the centre of Baltimore. 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. Baltimore sees about 24.6 days a year at or above 90°F and about 72.3 days with a tenth of an inch of precipitation or more.
