For some 21ºC it means a hot day, but for the British it can mean a day of unusual heat, as the UK has passed the hottest winter day in its history.
On 25 February, Monday, a record of more than 20 years was broken, only to be broken again the next day.
With the temperature recorded at 21.2 degrees celsius, it is possible to see the effects that the enormous accumulation of climate changes has been causing in the storms.
In February, parts of England became warmer than places in Malibu, Athens, Barcelona, and Crete.
