Normals: Period averages computed for a uniform and relatively long period comprising at least three consecutive ten-year periods (Technical Regulations).

Climatological normals are used as an average or baseline to evaluate climate events and provide context for year-to-year variability. Normals can be calculated ...

The standard climatological normal is derived from the observations of meteorological data calculated from the average over a 30-year period.

Climatological normals of monthly temperature and precipitation are defined as 30-year averages, where the current base period is 1991 – 2020.
