That's warm ! I used to see temperatures like that when I worked in Riyadh.
Some snippets of entirely useless information I now know from working there:
When a Toyota Rav 4 gets to 50C it's temperature gauge will display 4 dashed lines, whereas a Toyota Fortuner will display the numbers.
The reason for that was, when the temperature got to 50C, it was too hot for construction labourers to work, and by law they had to be sent home. Officially, it never got to 50C.
But 46C in the UK - that is Scorchio !
