(Rosie) A wee bit different here in my humpy. If you are interested I've posted a very broad but hardly usable short resume of the last 30-years from my location here
(Duj) Your annual average in the parched Australian outback is higher than mine in the Elevated Surrey Wetlands, which is 822 mm. (35 yr). But your rain-days are less than 2/3rds of mine. I've never had a rainless month but this June came closest (1.2 mm) which by UK standards is the square root of a mouse's ear'ole. Good; the "lawn" stops growing so less work. Heat Is Work and Work Is Heat and it's quite warm enough.
True, Rosie, but here it tends to come down in lumps. This, as you well know, results in run-off which is good for the creeks and rivers, but not for much else. Here will be found records for three consecutive years each of which is different. It also, though not deliberately, includes the heaviest rainfall I have recorded over an Australian Meteorological day (0900 to 0900).
I see 188 mm in a day. I bet that caused some mayhem. The best I've done is 68 mm but before I started recording there was a case of 175 mm over 2 days (1968) which put half of Surrey under water. We get a different kind of lumpiness, of course, solid cold lumpiness. Biggest level depth here 16" or 39 cm. (1987). Those were the days.
