Adelaide has had its coldest start to October in eight years and is on target for its coldest start in 62 years.
It has stayed colder than 19 degrees so far this month, which equals a feat achieved in October 2001. In that year, the first eight days of October were cooler than 19 before it warmed to 23 degrees on the ninth day of the month. In October 1947 each of the first 10 days were cooler than 19.
If Adelaide fails to reach 19 degrees on Friday this will be the city's coldest start to the month in 62 years.
Adelaide and much of southern South Australia has been under a spell of cloudy skies in cool southerly winds since the last day of September.
This weekend will be warmer as winds turn northerly, reaching the mid 20s on Sunday before another cool change on Monday. The cooler change will include a few days of rain, bringing as much as 15 to 30 millimetres to the south of the state. By the end of next week more than 40mm is possible in the Adelaide Hills and in the South East.
It will take until at least about the 20th day of this month before it reaches 30 degrees in the SA capital. In a normal October there are two-to-three days of 30 degrees or warmer.
