Mean daily temperature is the average air temperature for a complete 24 hour day. It is used in meteorology, climatology, agriculture, hydrology, and environmental science to represent the overall thermal conditions experienced during a single day. The value is typically calculated by averaging all temperature measurements recorded throughout the day. When continuous temperature records are not available, a common approximation is to average the day's maximum and minimum temperatures. The specific calculation method may vary depending on the observing organization and the data available, but the purpose remains the same: to provide a single representative temperature for the day.

| \( T_{max} \) = Maximum Daily Air Temperature at 2 Meters Height | \(^\circ F\) | \(^\circ C\) |
| \( T_{min} \) = Minimum Daily Air Temperature at 2 Meters Height | \(^\circ F\) | \(^\circ C\) |
