From late spring to late summer heat waves in 2022 smashed many records in North America between May and September of that year. Dozens of temperature records were surpassed in the United States. [2]
The first round of intense heat came on May 13, when Caribou, Maine hit 90 °F (32 °C), the second earliest on record. [3] The next day, three people who lived inside of a senior building passed away in Chicago, Illinois as a result of the heat, due to the air conditioning malfunctioning. [4] Later that month, in Memphis, Tennessee, when temperatures reached 91 °F (33 °C), an infant died after being left unattended inside of a motor vehicle. [5]
On May 21, 2022, heat became prevalent in the Mid-Atlantic, resulting in a near record hot Preakness Stakes horse race, with Baltimore and Philadelphia having temperatures of 95 °F (35 °C), Washington DC at 92 °F (33 °C), and New York City at 90 °F (32 °C). [6] This heat persisted into May 22, when Dulles International Airport hit 91 °F (33 °C), breaking the daily high record, and Westfield, Massachusetts hit 93 °F (34 °C). [7] Also on May 22, New York City sets a record high low temperature of 72 °F (22 °C), although the high of 89 °F (32 °C) was not a record. [8] Very brief intense heat returned on May 31, as much of the New York Metropolitan Area set record highs that day. [9] Toronto also recorded a record high of 32.2 °C (90.0 °F) that day. [10] Further south, schools released kids early that day due to the heat, with highs forecast in the upper 90s Fahrenheit. [11] However, by June 1, a backdoor cold front reduced temperatures dramatically. [12] On May 31, Boston dropped from 82 °F (28 °C) to 63 °F (17 °C) in ten minutes. [13]
A historic heat wave affected the Midwestern United States and Southeastern United States in the second week of June 2022. In Phoenix, a daily record was tied, as the mercury soared up to 114 °F (45.6 °C). [14] In North Platte, Nebraska, a record temperature of 108 °F (42 °C) was recorded. [15] In Death Valley, a man died when trying to refuel gas as temperatures climbed to 123 °F (51 °C). [16] In Rocky Mountain National Park, the excess heat resulted in rapid snowmelt, and the flooding forced a trail in the park to close. [17] A trail was also shut down at Joshua Tree National Park, where temperatures were predicted to reach as high as 117 °F (47 °C). [18] Temperatures in Memphis soared to 98 °F (37 °C), with a heat index of 110 °F (43 °C). This forced over 125 million people under excessive heat warnings. [19] In Odessa, Texas, thousands of residents were left without water, even as the temperature got to 105 °F (41 °C). [20] In San Antonio, every day in June 2022 was at least as hot as 97 °F (36 °C), except for June 28. [21] On June 13, St. Louis hit 100 °F (37.8 °C), breaking the daily record. In addition, from the 13–16, the morning low never went below 81 °F (27.2 °C), breaking the warmest morning low record for the next 4 days. In Chicago, Midway Airport recorded three days with high temperatures of at least 100 °F (38 °C) between June 14 and 21. [22] On June 17, the heat dome moved over the Mid-Atlantic briefly, causing a record high of 99 °F (37 °C) in Washington DC, and tying the record high of 96 °F (36 °C) in Baltimore. [23] [24] On June 20, Minneapolis set a daily record high of 101 °F (38 °C), with a heat index of 105 °F (41 °C). June 18 saw Mobile, Alabama have a record high of 100 °F (38 °C). [25] This was the first time Minneapolis saw triple digits in four years. Grand Forks, North Dakota saw a daily high record of 100 °F (38 °C) in June 19, and Houston and Galveston saw record highs of 101 °F (38 °C) and 97 °F (36 °C) respectively on June 20. [26] Heat in Alaska triggered 31 wildfires. [27]
An intense, fatal heat wave swept through the United States in July. More than 100 million people were put on heat alerts, and over 85% of the country had temperatures at or above 90 °F (32 °C). A man died in Dallas County, Texas, and a heat emergency was triggered in Washington DC due to temperatures over 95 °F (35 °C), on the weekend of July 23–24. This extreme heat severely intensifies drought conditions. Arkansas and Missouri went from 1% and 2% of their states from seeing severe drought or worse, to a quarter and a third. On July 17, Winnipeg saw their highest ever dew point, at 27.4 °C (81.3 °F). [28]
Temperatures in Abilene, Texas on July 20 hit 110 °F (43 °C), breaking a daily record. Austin, Texas also saw a daily high record of 104 °F (40 °C). Daily record high low temperature records were set, like in Needles, California, where the temperature never dipped below 95 °F (35 °C) on July 20. Record warm low temperatures were also set in Galveston (86 °F (30 °C)), Wichita Falls (84 °F (29 °C)), Houston (81 °F (27 °C)) and Laredo (81 °F (27 °C)), on July 20. [29] The heat wave was responsible for 18 other deaths, including 12 in Maricopa County, Arizona and one at Badlands National Park. [30] Witchita Falls hit 115 °F (46 °C) on July 20, a record for July, while on that day Oklahoma also reached that mark. Oklahoma City set a monthly record high of 110 °F (43 °C). [31] Further east, every day from July 20 to 24 in Newark, New Jersey got at or over 100 °F (38 °C), the longest streak on record. Boston also set a record high on July 24, at 100 °F (38 °C). [32] When the heat wave broke on July 25, multiple flash flood warnings were issued with the cold front. [33] While most parts of New Jersey exceeded 90 °F (32 °C) for the 8th day, New York City was kept to 86 °F (30 °C), thus keeping the heat wave to 6 days there. [34] Also, in New York City, for only the 3rd time, the entire month had highs above 80 °F (27 °C). [35] Overall, July 2022 was the 3rd warmest July on record, 8th for daily maximum but had the warmest daily minimums at record, at 63.57 °F (17.54 °C). Texas saw their warmest July on record, with an average high temperature of 100.2 °F (37.9 °C). [36]
Later on in the month, another heat wave in Portland, Oregon causes 14 additional deaths. Portland saw 7 consecutive days at or above 95 °F (35 °C), while Seattle saw six days at or above 90 °F (32 °C), both breaking records for duration, by July 31. [37]
Intense heat continued into August. In early August, a heat wave forced 80 million Americans under heat alerts. [38] Albany, New York set a new daily record high of 99 °F (37 °C) on August 4. [39] On August 7, Portland set a high temperature record of 96 °F (36 °C). [40] Boston set a new daily record high on August 8, at 98 °F (37 °C). [41] On August 9, Philadelphia got an excessive heat warning due to heat indexes over 105 °F (41 °C) for two consecutive hours. [42] This led to a ten day long heat wave in Philadelphia, while Boston saw temperatures above 95 °F (35 °C) for six days in a row. [43] Due to this, the New York Metropolitan Area had a top 5 hottest August, and Islip, New York and Newark, New Jersey had their warmest on record, [44] and so did Philadelphia a little bit to the southwest. [45] Further west, Missoula, Montana saw their hottest August on record, [46] while Portland, Oregon recorded their warmest ever month. [47] August, like July, was the warmest for daily minimums in the United States. [48] Oregon, Washington, Idaho, New Jersey, Connecticut, Rhode Island, Massachusetts and New Hampshire had their warmest August on record. [49] In addition, Newark set a record for the most days above 90 °F (32 °C) in August. [50]
On September 1, Death Valley hit 127 °F (53 °C), a global record for September. [51] That day, parts of Interstate 15 near Centerville, Utah buckled. [52] On September 4, a monthly record was set in Casper, Wyoming at 100 °F (38 °C). [53] Sacramento hit a record high on September 5, of 116 °F (47 °C). San Francisco also had a daily record that day of 97 °F (36 °C). [54] A monthly record high of Salt Lake City was set as well that day, at 103 °F (39 °C). [55] California's power grid nearly broke. [56] There were two deaths – one each in Arizona and Idaho. [57] Later on in the month, Nashville set their latest day at or above 100 °F (38 °C) on September 21. [58] Nevada and Utah saw their hottest September on record, and the 3rd quarter of 2022 for the United States as a whole was the hottest on record. [59] September 2022 became the hottest on record for the continent of North America at large. [60]
The 2003 European heat wave saw the hottest summer recorded in Europe since at least 1540. France was hit especially hard. The heat wave led to health crises in several countries and combined with drought to create a crop shortfall in parts of Southern Europe. The death toll has been estimated at more than 70,000.
Adelaide, the capital city of South Australia, has a Mediterranean climate, with mild wet winters and hot dry summers.
The 2006 European heat wave was a period of exceptionally hot weather that arrived at the end of June 2006 in certain European countries. The United Kingdom, France, Belgium, the Netherlands, Luxembourg, Italy, Poland, the Czech Republic, Hungary, Germany and western parts of Russia were most affected.
The 1936 North American heat wave was one of the most severe heat waves in the modern history of North America. It took place in the middle of the Great Depression and Dust Bowl of the 1930s and caused more than 5,000 deaths. Many state and city record high temperatures set during the 1936 heat wave stood until the 2012 North American heat wave. Many more endure to this day; as of 2022, 13 state record high temperatures were set in 1936. The 1936 heat wave followed one of the coldest winters on record.
The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States, Kazakhstan, Mongolia, China, Hong Kong, North Africa and the European continent as a whole, along with parts of Canada, Russia, Indochina, South Korea and Japan during July 29, 2010. The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. This lasted only from April 2010 to June 2010 and caused only moderate above-average temperatures in the affected regions, but it also set new record high temperatures for most of the area affected in the Northern Hemisphere.
The 2011 North American heat wave was a deadly summer 2011 heat wave that affected the Southern Plains, the Midwestern United States, Eastern Canada, the Northeastern United States, and much of the Eastern Seaboard, and had Heat index/Humidex readings reaching upwards of 131 °F (55 °C). On a national basis, the heat wave was the hottest in 75 years.
The Summer 2012 North American heat wave was one of the most severe heat waves in modern North American history. It resulted in more than 82 heat-related deaths across the United States and Canada, and an additional twenty-two people died in the resultant June 2012 North American derecho. This long-lived, straight-line wind and its thunderstorms cut electrical power to 3.7 million customers. Over 500,000 were still without power on July 6, as the heat wave continued. Temperatures generally decreased somewhat the week of July 9 in the east, but the high pressure shifted to the west, causing the core of the hot weather to build in the Mountain States and the Southwestern United States shifting eastwards again by mid-July. By early August, the core of the heat remained over the Southern Plains.
The 2013 extreme weather events included several all-time temperature records in Northern and Southern Hemisphere. The February extent of snow cover in Eurasia and North America was above average, while the extent of Arctic ice in the same month was 4.5% below the 1981–2010 average. The Northern Hemisphere weather extremes have been linked to the melting of Arctic sea ice, which alters atmospheric circulation in a way that leads to more snow and ice.
The 2013 heatwave in the United Kingdom and Ireland was a period of unusually hot weather primarily in July 2013, with isolated warm days in June and August. A prolonged high pressure system over Great Britain and Ireland caused higher than average temperatures for 19 consecutive days in July, reaching 33.5 °C (92.3 °F) at Heathrow and Northolt.
The summer of 2014 in Sweden was unusually warm, especially in the northern parts of the country. July was the warmest ever month on record in the north-west.
The 2018 Britain and Ireland heatwave was a period of unusually hot weather that took place in June, July and August. It caused widespread drought, hosepipe bans, crop failures, and a number of wildfires. These wildfires worst affected northern moorland areas around the Greater Manchester region, the largest was at Saddleworth Moor and another was at Winter Hill, together these burned over 14 square miles (36 km2) of land over a period of nearly a month.
The 2018 North American heat wave affected regions of Canada, where at least 70 deaths in Quebec were heat-related, the United States, where 18 states between Michigan and New Mexico issued heat advisories to a population of over 60 million people, and of Mexico, particularly the northwest and central regions.
The 2018 European drought and heat wave was a period of unusually hot weather that led to record-breaking temperatures and wildfires in many parts of Europe during the spring and summer of 2018. It is part of a larger heat wave affecting the northern hemisphere, caused in part by the jet stream being weaker than usual, allowing hot high-pressure air to linger in the same place. According to the European Drought Observatory, most of the areas affected by drought are across northern and central Europe. According to the World Meteorological Organization, the severe heat waves across the northern hemisphere in the summer of 2018, are linked to climate change in Europe, as well as events of extreme precipitation.
In late June and late July 2019 there were two temporally distinct European heat waves, which set all-time high temperature records in Belgium, France, Germany, Luxembourg, the Netherlands, and the United Kingdom.
Across Europe and parts of Asia, unusually high-temperatures in the late-winter period were reported from February 20 until February 28, 2021. The onset of the short-lasting winter heat wave was caused by a jet stream of Saharan dust. Daily high temperatures for the period were similar to the maximum high temperatures during spring.
The 2021 Western North America heat wave was an extreme heat wave that affected much of Western North America from late June through mid-July 2021. The heat wave affected Northern California, Idaho, Western Nevada, Oregon, and Washington in the United States, as well as British Columbia, and in its latter phase, Alberta, Manitoba, the Northwest Territories, Saskatchewan, and Yukon, all in Canada. It also affected inland regions of Central and Southern California, Nevada, and Montana, though the temperature anomalies were not as extreme as in the regions farther north.
In 2022, several areas of the world experienced heat waves. Heat waves were especially notable in East Asia, the Indian subcontinent, Australia, western Europe, the United States, and southern South America. 2022 heat waves accounted for record-breaking temperatures and, in some regions, heat-related deaths. Heat waves were worsened by the effects of climate change, and they exacerbated droughts and wildfires.
A number of heat waves began across parts of the northern hemisphere in April 2023, many of which are ongoing. Various heat records have been broken, with July being the hottest month ever recorded.
