How to read Oakland 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 Oakland Intl Ap, 7.1 km from the centre of Oakland. 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. Oakland sees about 3.1 days a year at or above 90°F.
