Severe weather events in Sydney

Severe weather events in Sydney is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Severe weather events in Sydney rather than just read about it. In short: Severe weather events or extreme weather events in Sydney, include hailstorms, thunderstorms, gale, bushfires, heatwaves, drought, and flash flooding (caused by East coast lows or black nor'easters). Sydney is rarely affected by cyclones, although remnants of cyclones do affect the city.

Key takeaways

Severe weather events in Sydney belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Severe weather events in Sydney to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Severe weather events in Sydney from memory before moving on to harder problems.

Reference excerpt

Severe weather events or extreme weather events in Sydney, include hailstorms, thunderstorms, gale, bushfires, heatwaves, drought, and flash flooding (caused by East coast lows or black nor'easters). Sydney is rarely affected by cyclones, although remnants of cyclones do affect the city. Global warming has increased the chances of extreme rain and flash floods in Sydney recently, such as the notable 2021 and 2022 flood events. Nevertheless, destructive heavy rainfall events have been recorded in the Sydney area since records began in the 18th century. Annually, coastal Sydney sees five heat-related deaths per 100,000 people while the western suburbs see 14 per 100,000. Heat-related deaths in the city were common in the late 19th and early 20th century period (due to lack of air conditioners) where several individual cases were reported.

Temperatures

1800s–1990s 5 January 1863 is Sydney's first recorded 40 °C (104 °F) day, when the mercury hit 41.6 °C (106.9 °F) at Sydney's Observatory Hill. On 19 July 1868, Observatory Hill recorded a maximum temperature of just 7.7 °C (45.9 °F), the lowest daily maximum temperature on record for Sydney. During January 1896, a state wide heatwave blasted through NSW and caused the mercury in Sydney to hit 40.7 °C (105.3 °F) on the 6th and 42.5 °C (108.5 °F) on the 13th, this ended Sydney's longest streak of days under 40.0 °C (104.0 °F) which lasted from 14 January 1870 – 5 January 1896. The heatwave also caused the death of 437 people across eastern Australia. On 10 January 1929, extreme heat kills thousands of fowls on poultry farms in the city as temperatures rose to 41.2 °C (106 °F). On 11 June 1931, Sydney registered its warmest June day on record at 26.9 °C (80.4 °F), this was more than 10 degrees above the average June temperature at the time. On 6 March 1938, Richmond in Sydney's north western area recorded the highest autumn temperature in the city's metropolitan area, shattering the previous record by almost 3C when it hit 41.9 °C (107.4 °F). On 1 April 1945, Sydney experienced its coldest April day in 86 years, with a minimum temperature of 10.8 °C (51.5 °F) and a maximum of 18.3 °C (64.9 °F). In 1972, Sydney recorded its coldest August day on record, with a maximum temperature of 9.1 °C (48.4 °F). On 1 February 1977, Sydney was hit by a massive heatwave that sent record breaking temperatures never seen in the month of February. Temperatures skyrocketed to 45.8 °C (114.4 °F) at Liverpool, more than 2 degrees hotter than anywhere else in Sydney. Other places that broke heat records at the time were Sydney CBD's second hottest day at 41.4 °C (106.5 °F), Bankstown 43.3 °C (109.9 °F), and Richmond 43.7 °C (110.7 °F) which stood as the hottest February days at both Bankstown and Richmond for 40 years. On 3 July 1984, Sydney CBD recorded a maximum temperature of just 9.6 °C (49.3 °F). On 27 July 1986, the temperature at Observatory Hill fell to 3.1 °C (37.6 °F), making it Sydney's coldest July morning in the instrumental record. The highest recorded minimum temperature in Sydney was registered at Orchard Hills, New South Wales, a suburb right beneath Penrith, at 29.8 °C (85.6 °F) on 9 January 1983. On 21 October 1988, Camden, Richmond and Parramatta recorded the first and only instance of a 40.0 °C (104.0 °F) during the month of October in Greater Sydney. Camden hitting 40.5 °C (104.9 °F), Richmond hitting 40.4 °C (104.7 °F) and Parramatta hitting 40.1 °C (104.2 °F).

Worked examples

Example 1 — a first encounter with Severe weather events in Sydney

Start with the simplest possible case. Write down what Severe weather events in Sydney claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Severe weather events in Sydney before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Severe weather events in Sydney ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Severe weather events in Sydney

In research: Severe weather events in Sydney appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Severe weather events in Sydney in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Severe weather events in Sydney is common in secondary-school and first-year university syllabi. It links to neighbouring topics Climate of Australia by city, Geography of Sydney, History of Sydney, so understanding it makes those chapters shorter.
In everyday life: Look for Severe weather events in Sydney outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
