The climatic conditions of a place over the course of a year are graphically represented in a climate diagram. Each month receives a separate entry. For this purpose, the temperature is always measured every full hour on every day of the month.

## The temperature is measured every day

This always takes place in the same place and under the same conditions. It arises for every day

- a maximum,
- a low value
- and a medium value.

With the help of the mean value, an average temperature value can be calculated 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, which represent the average temperature for a month at a specific location.

## Calculate average temperature

If you want to determine the mean annual temperature, all 12 values from the individual months must be added together. Then the calculated value is divided by 12. The result is the average annual temperature.

### Example:

(15 + 14 + 13 + 11 + 16 + 5 + 7 + 9 + 4 + 9 + 11 + 22) / 12 = 11.33

Average temperature values can be represented 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 on average in a location during the year, in which months the temperature is highest and in which months it is lowest. This can be particularly interesting and of great advantage when planning a trip.

In order to obtain a meaningful value in the long term, it is necessary to carry out the measurements over a period of several years. The more mean annual temperatures there are to compare, the more accurate the result and any outlier values can be better balanced.
