Katanning Comparison 10579 maximum temperature audit

At Katanning Comparison 10579 from 1 January 1907 to September 1972, whole .0 Fahrenheit degrees represented 32% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 4.4% of all maximum temperatures recorded.

1907-1972 represented 62.9% of the time span and had 39.9% of .0C and 26.1% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 22.5% of the total and .5C recordings represented 11% of the total of all fractions since 1972. Together, .0C and .5C represented 33.5% of all maximum temperatures recorded since metrication.
