Weather extremes
How extreme does Sydney's weather get?
The hottest, coldest, wettest and snowiest days Sydney has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Sydney has recorded — each shown against what a normal day that time of year looks like.
That is about 22°F hotter than a normal August afternoon in Sydney (typical high near 74°F).
The three most extreme on record
About 31°F colder than a normal February night in Sydney (typical low near 14°F).
The three most extreme on record
More rain in a single day than Sydney usually gets in the whole month of August (typical August total about 3.9 in).
The three most extreme on record
About 61% of a typical January's snow in a single day (Sydney averages roughly 29 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Sydney's record heat sits well above even a hot day for the season — August's 96°F is about 22°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
