The arithmetic mean of daily temperatures within a calendar month, derived from either the average of daily high and low temperatures or the sum of hourly temperature readings divided by the number of hours in the month, represents a standardized measure of the thermal environment experienced during that period. For example, if the daily average temperatures for January total 93C, dividing that sum by the 31 days of January yields an approximate value of 3C. This resulting value provides a generalized representation of the month’s overall temperature.
This standardized metric allows for meaningful comparisons of temperature patterns across different locations or time periods. Understanding temporal temperature fluctuations is vital for various sectors, including agriculture, where it informs planting schedules and crop selection; energy, where it aids in forecasting demand; and public health, where it assists in predicting heatwave impacts and managing cold-related illnesses. Historical records of this parameter are also critical for climate change studies, allowing researchers to assess long-term warming trends and their associated consequences.
