York Post Office 10144 maximum temperature audit

At Wandering Comparison 10648 from 1 January 1934 to September 1972, whole .0 Fahrenheit degrees represented 29.5% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 6.4% of all maximum temperatures recorded.

1934-1972 represented 62.9% of the time span and had 55.1% of .0C and 24.9% of .5C maximum temperatures within the entire temperature record.

From September 1 1972 to 11 May 1996, maximum temperature recordings of .0 Celsius degrees represented 13.1% of the total and .5C recordings represented 8.8% of the total of all fractions since 1972. Together, .0C and .5C represented 21.9% of all maximum temperatures recorded since metrication.
