A daily record low temperature for Waterloo has been set this morning, so it is good timing to look at the yearly frequency of setting a new high and low record temperature. The featured chart presents this metric by computing the number of new records set each year from the beginning of the period of record. The black line represents a sort of theoretical expected frequency based on the number of years that have passed. During the beginning of the record, there are much fewer years of history so it is a bit 'easier' to set records. Years that exceed this expectation are colored differently. For recent years, the warm weather of 2012 certainly stands out as an anomaly.
