//The plummeting temperatures brought some relief to Sydneysiders after a
sweltering day which saw the mercury hit a record-breaking 45.8C
at Sydney's Observatory Hill at 2.55pm (AEDT) \\
//The Australian city of Sydney is experiencing its hottest day on record,
with temperatures reaching nearly 46C.
A temperature of 45.8C was recorded at Observatory Hill in the city at 14:55
local time (01:55 GMT).
Some areas in the wider Sydney region were even hotter, with the town of
Penrith, to the west, registering a temperature of 46.5C.\\
45.8 c = 114.4 f
46.5 c = 115.7 f
Design conditions for Sydney are 90 f DB 73 WB
So I guess lots of buildings would have had very hot areas.
