Extreme weather events in Melbourne , Australia have occurred on multiple occasions. The city has experienced a number of highly unusual weather events and extremes of weather. An increase in heat waves and record breaking temperatures in the 21st century has led to much discussion over the effects of climate change in the country. [1] [2]
Many of the hottest days recorded in Melbourne occurred during major heatwaves which precipitated large firestorms:
Melbourne's warmest overnight temperature was 30.5 °C (86.9 °F) on 1 February 1902 and 29 January 2009.
Melbourne's coldest daytime temperature was 4.4 °C (39.9 °F) on 4 July 1901.
Melbourne's coldest temperature ever was −2.8 °C (27.0 °F) on 21 July 1869. [52]
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms produce little precipitation or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
Adelaide has a Mediterranean climate, with mild wet winters and hot dry summers.
Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia.
The climate of Minneapolis–Saint Paul is the long term weather trends and historical events of the Minneapolis–Saint Paul metropolitan area in east central Minnesota. Minneapolis and St. Paul, together known as the Twin Cities, are the core of the 15th largest metropolitan area in the United States. With a population of 3.6 million people, the region contains approximately 60% of the population of Minnesota. Due to its location in the northern and central portion of the U.S., the Twin Cities has the coldest average temperature of any major metropolitan area in the nation. Winters are very cold, summer is warm and humid, snowfall is common in the winter and thunderstorms with heavy rainfall occur during the spring, summer and autumn. Though winter can be cold, the area receives more sunlight hours in mid-winter than many other warmer parts of the country, including all of the Great Lakes states, the Pacific Northwest, parts of the South, and almost all of the Northeast. Unless otherwise indicated, all normals data presented below are based on data at Minneapolis/St. Paul International Airport, the official Twin Cities climatology station, from the 1981−2010 normals period.
The climate of Sydney, Australia is humid subtropical, shifting from mild and cool in winter to warm and occasionally hot in the summer, with no extreme seasonal differences as the weather is moderated by proximity to the ocean, although more contrasting temperatures are recorded in the inland western suburbs. Despite the fact that there is no distinct dry or wet season, rainfall peaks during summer and autumn months, and is at its lowest just around the middle of the year, though precipitation can be erratic throughout the year. Precipitation varies across the region, with areas adjacent to the coast being the wettest. According to the Bureau of Meteorology, Sydney falls in the temperate climate zone which has warm to hot summers and no dry season. Sydney's plant hardiness zone ranges from zone 11a to 9b throughout the metropolitan area. Under the Holdridge Life Zones classification, eastern Sydney falls in the Subtropical Moist Forest zone and the western suburbs in the Subtropical Dry Forest zone.
The climate of Houston is classified as a humid subtropical climate, with tropical influences. August normally ranks as the warmest month at an average temperature of 95 °F (35 °C) and January the coldest month at an average temperature of 63 °F (17 °C).
Australia's climate is governed mostly by its size and by the hot, sinking air of the subtropical high pressure belt. This moves north-west and north-east with the seasons. The climate is variable, with frequent droughts lasting several seasons, thought to be caused in part by the El Niño-Southern Oscillation. Australia has a wide variety of climates due to its large geographical size. The largest part of Australia is desert or semi-arid. Only the south-east and south-west corners have a temperate climate and moderately fertile soil. The northern part of the country has a tropical climate, varying between grasslands and desert. Australia holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, and the highest sunshine duration.
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal phenomena include blizzards (snowstorms), ice storms, and duststorms.
In Australia, the Federation Drought is the name given to a prolonged period of drought that occurred around the time of Federation in 1901.
The climate of Miami is classified as having a tropical monsoon climate with hot and humid summers; short, warm winters; and a marked drier season in the winter. Its sea-level elevation, coastal location, position just above the Tropic of Cancer, and proximity to the Gulf Stream shape its climate.
The climate of Allentown, Pennsylvania is classified as a humid continental climate. Allentown's warmest month is July with a daily average temperature of 74.7 °F (23.7 °C) and the coldest month being January with a daily average of 29.4 °F (−1.4 °C). The average precipitation of Allentown is 45.35 inches (1,152 mm) per year.
The 2010 Western Australian storms were a series of storms that travelled over southwestern Western Australia on 21 and 22 March 2010. One of the more intense storm cells passed directly over the capital city of Perth between 3:30 pm and 5:00 pm on Monday 22 March 2010. As of 2024, it is still the costliest natural disaster in Western Australian history, with the damage bill estimated at A$1.08 billion.
Dubai features a tropical desert, hot arid climate. Dubai has two seasons – winter and summer. Rainfall has been increasing over the past few decades in the city accumulating to more than 130 mm (5.12 in) per year.
The Geography of Atlanta encompasses 132.4 square miles (342.9 km2), of which 131.7 square miles (341.1 km2) is land and 0.7 square miles (1.8 km2) is water. The city is situated among the foothills of the Appalachian Mountains, and at 1,050 feet (320 m) above mean sea level, Atlanta has the highest elevation among major cities east of the Mississippi River. Atlanta straddles the Eastern Continental Divide, such that rainwater that falls on the south and east side of the divide flows into the Atlantic Ocean, while rainwater on the north and west side of the divide flows into the Gulf of Mexico. Atlanta sits atop a ridge south of the Chattahoochee River, which is part of the ACF River Basin. Located at the far northwestern edge of the city, much of the river's natural habitat is preserved, in part by the Chattahoochee River National Recreation Area.
The Australian summer of 2012–2013, known as the Angry Summer or Extreme Summer, resulted in 123 weather records being broken over a 90-day period, including the hottest day ever recorded for January on record, the hottest summer average on record, and a record seven days in a row when the whole country averaged above 39 °C (102 °F). Single-day temperature records were broken in dozens of towns and cities, as well as single-day rainfall records, and several rivers flooded to new record highs.
Perth, the capital city of the state of Western Australia, has a Mediterranean climate, with hot, dry summers and mild, wet winters. February is the hottest month of the year, with an average high of 31.6 °C (88.9 °F), and July is the coldest month of the year, with an average low of 7.9 °C (46.2 °F). 77% of rain in Perth falls between May and September.

Melbourne, the state capital of Victoria and the second most populous city in Australia, has a temperate oceanic climate, bordering on a humid subtropical climate, and is well known for its changeable weather conditions. This is mainly due to Melbourne's geographical location. This temperature differential is most pronounced in the spring and summer months and can cause strong cold fronts to form. These cold fronts can be responsible for all sorts of severe weather from gales to severe thunderstorms and hail, minor temperature drops, and heavy rain. The city experiences little humidity in summer, except at the end of hot spells following thunderstorms and rain.
Brisbane has a humid subtropical climate with year-round period with warm to hot temperatures. Brisbane generally experiences 3 months of mild cool winter from June to August.
