In a climate diagram, the climatic conditions of a place over the course of a year are graphically displayed. Each month receives a separate entry. For this purpose, the temperature is always measured on the hour every day of the month.
The temperature is measured every day
This always happens at the same place and under the same conditions. For each day there is
- a maximum value,
- a minimum value
- and an average value.
With the help of the mean value, an average temperature value can be formed for an entire month. This is then entered as a point in the climate diagram.
Over the course of a year, there are 12 points in the climate diagram that represent the average temperature for a month at a specific location.
Calculate the average temperature
If you now want to determine the mean annual temperature, all 12 values from the individual months must be added together. The determined value is then divided by 12. The result is the average annual temperature.
(15 + 14 + 13 + 11 + 16 + 5 + 7 + 9 + 4 + 9 + 11 + 22)/12 = 11.33
Average temperature values can be displayed graphically very well. The benefit of such diagrams is that they can give the reader a quick first impression of the climatic conditions in a place.
At first glance, you can see how warm or cold it is in a place on average in a year which months the temperature is highest and in which months it is lowest. This can be interesting and of great advantage, especially when planning a trip.
In order to obtain a value that is meaningful in the long term, it is necessary to carry out the measurements over a period of several years. The more average annual temperatures there are to compare, the more accurate the result will be and any outlier values can be better compensated for.
