This is nothing new. In 1979/80 whilst working at Iraqi Airways there was a similar reg except the trigger temp was something like 50C. Obviously the reported temp never exceeded 49C!!
(My thermometer recorded way in excess of 50C quite often)
In the 80's at Gulf Air, one summer morning the ATIS at Bahrain was reporting some temp that made me ask dispatch to unload 10 tons of cargo. "Standby," was their reply. Five minutes later I was instructed to recheck the ATIS. Laughingly, the mid morning temp had suddenly decreased a couple of degrees.
