The Very Unusual Nature of recent rain in Sydney
Don White
I have added a few facts about the recent rains in Sydney.
Number of rain days in a month is difficulty to access so I would stanf corrected on these if possible.
However it seems likely that for number of days in all categories the last month and two months have been out of their own.
In Sydney, Wettest 1, 2, 3 & 4 months (1859 to present)
