In 112 years it has not been this cold on May 23 as it was today. So says Weatherplaza. In parts of Noord-Brabant and Limburg it did not get warmer than 8 degrees, in Noord-Holland and Friesland 11 degrees.
In the Noordoostpolder it was the warmest with 11,7 degrees. For a long time the cold record from May 23, 1975 seemed to be broken. That day it did not get any warmer than 10,4 degrees in De Bilt. But because around 18:20 the temperature shortly rose to 10,5 degrees, so that record still holds.
The reason that you were wearing probably a winter coat today is polar air that has invaded our country. Also the North Sea water was colder than normally, so this could not warm the incoming air. According to Weatherplaza this weekend it is not getting any better. Next week temperatures will be rising a little bit, but it stays clearly much colder than normal.

Comment from Argiris: The weather station De Bilt in the Netherlands has moved its Stevenson hut a few times, resulting in warm bias, this fact is mentioned on WUWT.
Also there is a busy road nearby and 18:20 this road is still busy. But these facts are never mentioned in the MSM.
