Geraldton Airport Comparison 8051 maximum temperature audit

At Geraldton Airport Comparison 8051 from 24 August 1941 to September 1972, whole .0 Fahrenheit degrees represented 14.9% of all maximum temperatures recorded.

1941-1972 represented 45.1% of the time span and had 29.9% of .0C and 28.7% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 11.7% of the total and .5C recordings represented 8.5% of the total of all fractions since 1972. Together, .0C and .5C represented 20.2% of all maximum temperatures recorded since metrication.
