Sydney is on track to have its driest September on record and the second driest calendar month since records commenced in 1858. Despite a few light drops of rain peppering parts of Sydney this morning, nothing was registered in the gauge at Observatory Hill. The city has only collected 0.2mm of rain so far this month, which is the lowest possible amount Sydney's rain gauge can register. With dry weather likely to persist during the final days of the month, this meagre amount is set to go down as Sydney's lowest September rainfall total in recorded history. Sydney's previous September record was 2.1mm from 1882. This September is also on track to go down as Sydney's second driest calendar month in 159 years of records. August 1995 was the city's only completely dry (0mm) calendar month in history. Sydney's parched parks and gardens will stay thirsty during the opening days of October, although there are signs that some rain is on the way. A trough and front moving across NSW may produce the city's first decent rainfall since early August towards the end of next week.
