Its a dry year – thoughts on top of St Mary’s Peak, Flinders Ranges, South Australia – 2/10/2018

January February March April May June July August September October November December Annual Total mm
2017 23.2 6.2 1.2 45.8 18.4 2 7.2 32.8 3.8 10.6 32.8 39 223
2018 7.6 3.2 1.6 2.8 12 24.4 9 24.8 2.8

While I was sitting, I was thinking about rain. Back at our site in the Mallee near Renmark, rain was only up in June 2018, 24.4 mm compared to 2mm in June 2017. Average annual total for Renmark is 250 mm from 21 years. There is a pattern of above average rainfall every 5 years, with 354.4 and 299 mm in 2000 and 2001; 264.8 mm in 2005; 419.8 and 457.4 mm in 2010 and 2011; 392 mm in 2016.

We had a whopping 147.8 mm on the 28th September 2016. Looks like the mallee trees may have to wait until 2020 for some decent rain…………..
