Temperatures in Los Angeles must be due to climate but the cold in Sydney is probably only weather !!!
From the Sydney Morning Herald:
After their coldest winter in 13 years Sydney residents have just experienced their coldest September in five years. “September was an unusual month in terms of the lack of warm days across much of south-eastern Australia,” weatherzone meteorologist Brett Dutschke said.
When both daytime and overnight temperatures were combined, Sydney’s average temperature this month came in at just under 17 degrees. This made it the coldest September in five years, despite being one degree above the long-term norm. It was also the coldest September in terms of daytime temperatures in three years.

As far as rainfall goes, Sydney failed to receive the long-term monthly average of 69mm, despite having the normal number of rain days, 10. The city gained only 42mm, the lowest for September since 2007.
“With La Nina likely to peak in the next few months, we are expecting rainfall to increase, trending to near or above average into summer,” Mr Dutschke said. “During this period, daytime temperatures should be near or below average. Overnight temperatures are likely to be close to normal.”
Residents of Melbourne have just experienced their coldest September days in 16 years, Mr Dutschke said. Warmer days ahead will provide Adelaide residents with a good thawing out after enduring their coldest September in 18 years, Mr Dutschke said.
