Carnarvon Airport 6011 maximum temperature audit

At Carnarvon Airport 6011 from 10 January 1945 to September 1972, whole .0 Fahrenheit degrees represented 15.6% of all maximum temperatures recorded.

1945-1972 represented 41.8% of the time span and had 25.7% of .0C and 23.8% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 11.9% of the total and .5C recordings represented 9.2% of the total of all fractions since 1972. Together, .0C and .5C represented 21.1% of all maximum temperatures recorded since metrication.
