The main feature of the weather across the Nation during the past 5 days has been a notable increase of maximum temperatures in some inland areas. The temperature last Thursday 6th October reached 39.5 at Eucla and 36.8 at Ceduna and on Sunday 9th October reached 41.3 at Oodnadatta and 36.2 at Mildura. These high readings are certainly a significant change from the below normal maxima experienced for most of September and is a sign of drier conditions this month.
Taking the 41.3 at Oodnadatta, there were similar high readings for early October in 1952, 1970, 1972, 1980, 1999, 2004 and 2007. All these episodes saw the next significant rain event in our regions up to three weeks away in late October and heavier rain in November.
Last month both Darwin and Broome had a near record high minima for September and there were similar cases occurring in 2010, the 1990's, 1983, 1973-74, 1950, 1952 and 1917 and all these led to excessive rains well into the next summer.
Darwin last Saturday 8th October had it's hottest October day since 2009 with a reading of 37.5. It was unusual to have such a hot day after the wettest September there since 1984. In 2009 there was a wet September with 35 mms at Darwin and the following summer was notably very wet in our regions with frequent thunderstorms and flash flooding.
