Is there any way to "class" different months based on e.g. mean
temperature and precipitation, so you can put it into a certain
category, resulting something like:
January CET:
below:
2°: Chilly
1°: Cold
0°: Unusually cold
-1°: Very cold
-2°: Extremely cold
-3°: Severe
-4°: Exceptional

(Or any synonym of "very very cold" you could find, sorry if I've
might have stolen the examples subconsiously...)
It would be quite interesting, especially with some of the more
exceptional months...
Anyone here who likes the idea?

In its monthly summaries the Belgian Royal Meteorological Institute
uses the following terms to describe the key statistics of the month -
average temperatures, rainfall total, average air pressure, etc.

normal - likely to occur at least once in 5 years
unusual - likely to occur once in 6 years
very unusual - likely to occur once in 10 years
exceptional - likely to occcur once in 30 years
very exceptional - likely to occur once in 100 years
