style="color:black">The average annual rainfall is 901 millimetres
(35.5 in), with the majority falling in winter, autumn and spring. Much of
the autumn and spring rain falls in heavy downpours on a limited number of
days, but in winter it is spread more evenly over a large number of days.
Summer receives very little rainfall, if any. Snow is rare, except in the mountainous eastern suburbs, where snowfall is common due to the region's high
altitudes. Large snowstorms, however, occurred in 1920, 1942 and 1950
