Below are charts of all 112 weather station locations in the Australian Bureau of Meteorology's ACORN dataset showing their annual percentages of truncated/rounded .0 raw minimum and maximum degrees with corresponding raw national annual temperatures from 1910 to 2013.

The charts illustrate averages of all annual minima, maxima and percentages of temperatures truncated or rounded to .0F (.94><.06) and .0C at all stations.

Note: all temperatures analysed on this page are from the Bureau's of Meteorology's Climate Data Online. This means an unknown quantity of daily temperature records have been quality control homogenised, or adjusted, particularly old weather records - e.g. Torok 1996 1 (PDF 1.2mb) and 2 (PDF 23.6mb). Some stations also have significant missing data gaps in different years, affecting their calculated annual averages.

Alternatively, the data can be charted as the average number of days that a truncated .0 minimum or maximum was recorded at all Australian weather stations each year:

The .94><.06 definition of an original .0 Fahrenheit recording is probably an underestimate. Read more.
