August came in below-average for the Port Pirie region of SA, with precipitation for the month also well-below the norm for the third consecutive year. While looking forward, brutal Antarctic air masses look set to envelope the entire Australian continent by mid-September.
Nights in Port Pirie averaged just 4.1C (39F) in August 2019, according to data from Australia’s Bureau of Meteorology (BOM) — that’s 1.4C below-the-norm and the lowest since the 2.8C (37F) averaged during 2008 (solar minimum of cycle 24).
In addition, only one night in Port Pirie rose above 10C (50F) in August this year, which is a new record for the weather station.
Digging deeper still, minimums ranged from 10.8C (51F) to -0.6C (31F), and a total of four nights fell below zero, which is two more than normal. Days averaged 17.3C (63F), compared with the 18.1C (65F) average, and were the coldest since Aug 2010’s 16.3C (61F).
Also worth noting, the BOM website has two two days with missing data for Aug 2019 — one max and one min, on day 29 (18.3C?) and day 30 (-0.3C?), respectively.
The Port Pirie region is geographically positioned beside Spencer Gulf in the mid north of South Australia. It has farming listed as one its main industries, and those in the area with a vested interested in open-field crops and hoping for a gentle transition into meteorological spring may want to close the browser now.
Latest GFS-runs reveal the frigid, below-average temps will continue into the first weeks of September where they won’t just be confined to SA but will also extend north infecting large portions of the continent, particularly Central and Eastern regions:
But all that looks set to be a mere precursor to cold-horror-show expected by mid-September –just as farmers look to the “optimal flowering period” of early spring– as an enormous Antarctic Blast looks set to engulf the entire Australian continent sinking temps some 12-or-more C below average, ravaging tender crops:
For Australia’s wheat belt, this optimal flowering period is generally in September.
At this time the soil is still moist after the cool, wet winter; days are getting longer and sunnier; maximum temperatures are still relatively low; and frosts are less frequent.
But if crops flower outside the optimal window, or the window never actually opens, yields decline sharply.
The cold times are returning, in line with historically low solar output.
