Roebourne 4035 maximum temperature audit

At Roebourne 4035 from 1 January 1957 to September 1972, whole .0 Fahrenheit degrees represented 33.8% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 3% of all maximum temperatures recorded.

1957-1972 represented 29.1% of the time span and had 23.6% of .0C and 9.8% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 12.1% of the total and .5C recordings represented 8.7% of the total of all fractions since 1972. Together, .0C and .5C represented 20.8% of all maximum temperatures recorded since metrication.
