Please see [[Meteorological day]] for discussion about WMO standard way to calculate average temperature from sum of minimum in previous 12 hours and maximum in subsequent 12 hours, divided by two. | |||

The average temperature for the day, is calculated by Cumulus using samples of the temperature taken at 1-minute intervals (sometimes called the 'integration method'). (This assumes Cumulus is running continuously, if it has just been restarted, for some station types Cumulus will use the temperatures stored at the console logging interval for the period since Cumulus previously ran). Each minute the new measurement is added onto the accumulator ''Total'' and increments by one the counter ''Samples'' in the [[today.ini]] log file. | The average temperature for the day, is calculated by Cumulus 1 using samples of the temperature taken at 1-minute intervals (sometimes called the 'integration method').

For MX, the sampling may be every second. | |||
