# Calculate the mean annual temperature in the climate diagram 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.
