A warm week has come to an end – and with it, the high temperatures that dominated our weather over the past seven days. 
As the week drew to a close, we saw a cold change sweep up the South Island, tumbling temperatures by double digits in less than 10 minutes.

Dunedin soared to 27 degrees on Friday, before rapidly dropping down to just 16 degrees.  
Some areas further south were even colder, only slightly above double digits.
Next Tuesday we expect an even colder southerly to move through, dropping both Dunedin and Invercargill’s high to possibly just 12 degrees.
Welcome to the first signs of Autumn.

In slightly better news, it’s been noted that this year an odd tranquility has filled the heart of the Southern Hemisphere’s tropical cyclone season.
In a turn of events that’s mystified even the experts, hurricane-strength cyclones have been virtually absent since July from the entire Indian Ocean and Pacific Ocean south of the equator.
Check out this think piece from Wunderground, exploring the situation.

Across the ditch, parts of Australia’s eastern seaboard could receive more than a month’s worth of rain in the next week, raising the risk of flooding during the opening days of autumn.
