Monthly mean minimum temperature

Mitchell Post Office

The Monthly mean minimum temperature is the average of all available daily minima for the month. The Daily minimum air temperature is nominally recorded at 9 am local clock time. It is the lowest temperature for the 24 hours leading up to the observation, and is recorded as the minimum temperature for the day on which the observation was made. Temperature data prior to 1910 should be used with extreme caution as many stations prior to that date used non-standard shelters. About temperature data

Key: Units = °C. 12.3 = Not quality controlled or uncertain, or precise date unknown

Data within the table which are in italics represent observations which have not been fully quality controlled, a process which may take a number of months to complete. While these data may be correct, you should exercise caution in their use.

Gaps occur in the table where there are missing valid daily observations within the month. This is frequently associated with the observer being unavailable (where observations are undertaken manually), a failure in the observing equipment, or when an event has produced suspect data.
