Tuesday morning marks a cold coincidence as Perth shivered through the coldest morning of the year.

Perth's minimum temperature dropped to 2.3 degrees at 6.45am, and Perth Airport was even colder at 1.8 degrees.

"This is a bit spooky. The last time it was colder than the 2.4 in #perth was 23rd June 2014, with 2.1," Tweeted Bureau of Meteorology spokesman Neil Bennett.

No wind or cloud cover will warm the city up with the mercury set to climb no higher than 16 degrees on a calm and clear day.
