How are Monthly Means Calculated?

The table shows values for each month of the selected year in the database. Values are given in degrees Celsius. Averages shown here are calculated from daily averages for the month. The value in parentheses following the monthly mean value is the standard deviation of the daily averages used to compute the mean. The minimum (maximum) is the average of the minimum (maximum) temperature observed on each day of the selected month. Table rows are shown in descending order of Mean value. In some cases the present month may be incomplete.

The values are plotted so that the minimum and maximum are marked at the end of the whiskers, the mean value is shown with a horizontal tick across each box, and the boxes show the range of plus and minus one standard deviation from the mean value. The average temperature is shown with a dashed horizontal line and the average extremes are drawn with dotted lines. The blue curve is a spline that connects the monthly means.
