No. Climate scientists generally use a 30-year average to which current temperatures can be compared as “departures from normal.” This 30-year period is often referred to as the “climate normal, and is updated every 10 years for the most recent 30-year period (the data set widely used now is from 1971-2000; previous data sets were from 1951-80 and 1961-90). We are now starting to use a 100-year (1901-2000) normal for national statistics. But once a daily record temperature is verified, it s included in a historical data set, which includes all data for the location’s period of record, which is different from the climate normal data set.
