Perth's Record Cold


The cold snap in July, 1997, saw the all time record minimum temperature for Perth City broken three times and saw 16 days in a row of temperatures under 7 C, with all of those days except for two under 4 C.

It commenced on the 8th July, 1997 when an all time record low was established with a minimum of 0.4 C, breaking the old record of 1.2 C back on the 7th July, 1916. This was broken again three days later with 0.2 C and then Perth City's first official freeze and new all time record low of 0.0 C occurred on the 15th July, 1997.

The cold nights lasted for 16 days, with six of those nights having temperatures under the old 1916 record of 1.2 C.

A large high pressure system which brought clear skies and light winds was responsible for the cold nights and gave fine, sunny and cool to mild days.
