2.  Sydney is the state

Wales and the most
populous

 It is located on
Australia's east coast,
the metropolis
surrounds the world's

and sprawls towards the

3.  Sydney has a humid subtropical climate with
warm summers, cool winters and uniform
rainfall throughout the year.
 The weather is moderated by proximity to the
ocean, and more extreme temperatures are
recorded in the inland western suburbs.
 Sydney experiences an urban heat
island effect. This makes certain parts of the
city more vulnerable to extreme heat.

4.  Rainfall is fairly evenly spread through the
year, but is slightly higher during the first half
of the year. The rainfall has a moderate to low
variability.
 The average annual temperature of the sea is
above 21 °C (70 °F), and the monthly average
ranges from 18 °C (64 °F) in July to 24 °C
(75 °F) in January.

8.  Averaging at 13.8 km/h (8.6 mph), November
is the windiest month, whilst March is the
calmest at 11.3 km/h (7.0 mph).
 The prevailing wind is northeasterly.
 In the warm months, only 40% of the time
Sydney would receive wind directions from
the northwest or southwest, which are the dry
winds flown from the heated interior of
Australia.
 Northeaster lies and easterly sea breezes are
dominant in late spring to early autumn.

9.  Westerlies are dominant in late winter to mid-
spring. Southerly busters are expected from
November to the end of February.
 They typically look like as if a sheet of cloud is
rolled up like a scroll by the advancing wind.
 The change of wind (in the warm months) is
sometimes very sudden, where it may be
fresh northeasterly and in ten minutes a
southerly gale.

10.  When the subtropical ridge is north of Sydney
in the second half of the year (spring), the
wind would come from the west or inland.
 As the ridge moves south in late summer and
autumn, the winds become easterly and,
because they are coming off the Tasman Sea,
they are moist.
 Rainfall would be the highest at this time of
the year (autumn to early winter).
