SYDNEY, AU RALIA
Sydney is the state capital of New South Wales and the most populous city in Australia and Oceania. Located on Australia's east coast, the metropolis surrounds
Port Jackson and sprawls about 70 km (43.5 mi) on its periphery towards the Blue Mountains to the west, Hawkesbury to the north and Macarthur to the south.
[9] Sydney is made up of 658 suburbs, 40 local government areas and 15 contiguous regions. Residents of the city are known as "Sydneysiders". As of June 2017
Sydney's estimated population was 5,131,326.
Under the Köppen–Geiger classification, Sydney has a humid subtropical climate (Cfa) with warm summers, cool winters and uniform rainfall throughout the year.
At Sydney's primary weather station at Observatory Hill, extreme temperatures have ranged from 45.8 °C (114.4 °F) on 18 January 2013 to 2.1 °C (35.8 °F) on 22
June 1932. An average of 14.9 days a year have temperatures at or above 30 °C (86 °F) in the central business district (CBD). In contrast, the metropolitan area
averages between 35 and 65 days, depending on the suburb. The highest minimum temperature recorded at Observatory Hill is 27.6 °C (82 °F), in February 2011
while the lowest maximum temperature is 7.7 °C (46 °F), recorded in July 1868.
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, including coastal suburbs. In late spring and summer, temperatures
over 35 °C (95 °F) are not uncommon, though hot, dry conditions are usually ended by a southerly buster. This powerful storm brings gale winds and rapid fall in
temperature, followed by brief heavy rain and thunder. The far-western suburbs, which border the Blue Mountains, experience a Föhn-like wind in the warm
months that originates from the Central Tablelands. Due to the inland location, frost at night is recorded in Western Sydney a few times in winter. Autumn and
spring are the transitional seasons, with spring showing a larger temperature variation than autumn.
