Sydney just had one of its driest June to May periods on record.
The city has registered below average rainfall on all but one month since April 2017. This included its second driest calendar month on record, when just 0.2mm of rain reached the gauge during September last year.
More recently, Sydney has only received 311mm of rain so far during 2018, which is well below its long-term average of 597mm between January and May. This has been the city's driest start to a year since 2006.
Between the start of June 2017 and 9am today (Thursday), Sydney had only recorded 694mm of rain. This figure is unlikely to change much by the end of the month, with little, if any rain expected during the next week. If Sydney stays under 712mm by the end of May, this will have been Sydney's sixth driest June to May period on record and the driest since 2006.
Unsurprisingly, Sydney's water storage level has been dropping steadily since April last year. According to Water NSW, Warragamba Dam is currently sitting at 73.7 per cent of its capacity, which is down from 94.5 per cent at the same time last year.
Sydney's total water supply volume is down to around 71.2 per cent, which is its lowest level in more than six years.
