Esperance 9789 maximum temperature audit

At Esperance 9789 from 29 June 1969 to September 1972, whole .0 Fahrenheit degrees represented 14.9% of all maximum temperatures recorded.

1969-1972 represented 9.3% of the time span and had 4.7% of .0C and 3.1% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 11.5% of the total and .5C recordings represented 10.6% of the total of all fractions since 1972. Together, .0C and .5C represented 22.2% of all maximum temperatures recorded since metrication.
