Heat Wave

Go To
"Anyone call for roast duck?"

"There was a desert wind blowing that night. It was one of those hot dry Santa Anas that come down through the mountain passes and curl your hair and make your nerves jump and your skin itch. On nights like that every booze party ends in a fight. Meek little wives feel the edge of the carving knife and study their husbands' necks. Anything can happen. You can even get a full glass of beer at a cocktail lounge."
Raymond Chandler, "Red Wind"

The temperature is 115 plus degrees Fahrenheit (46 degrees Celsius), and people are soaked with sweat. It's the hottest it's ever been since June 26, 1889. You could fry an egg on the sidewalk. Everyone has their air conditioner cranked up, and those not fortunate enough to own one are desperately looking to cool down. Just staying outside for a prolonged period of time can be dangerous. No one wants to move. Everyone is understandably cranky because of the hot weather, but according to the weatherman, there's no sign of things cooling down.

It's the Heat Wave, a common device employed by writers to increase irritability and stress among characters Locked in a Room and Getting Hot in Here, in a Hostage Situation, in a Die Hard Plot, or in a climactic Courtroom Battle. In TV episodes and movies in which the entire plot takes place in one day, the Heat Wave will be dubbed in-universe as The Hottest Day of the Year. Alternatively, or additionally, the Heat Wave may serve as a symbolic metaphor for the tension or anger that builds up among the characters throughout the story.

Of course, the heat can also serve as a good excuse for having characters walk around in skimpy or soaked-to-the-skin clothing.

See also Big Blackout. Like Snowed-In and Rain, Rain, Go Away, an aversion of It's Always Spring. Contrast Cold Snap, the other temperature extreme. Often a sign that A Storm Is Coming, in fiction as in real life.

Not to be confused with It Was a Dark and Stormy Night. Unless the night was sultry. See also Fat, Sweaty Southerner in a White Suit.

A.k.a. Long Hot Summer (media shorthand for the urban riots of the '60s-70s) or The Dog Days Of Summer.

  • Rear Window: At the beginning of the film, the camera lingers on a thermometer showing the temperature as 90 degrees (32.2 °C). The same day, one of the characters remarks that trouble seems to be brewing. Sure enough, it is.

  • A frequent device in The Dresden Files. Summer Knight makes the most use of the heat wave motif, feeding into Harry's irritability given his recent defeat and helping to highlight how things are going seriously wrong with the Summer fae.

    The baby frets. The maid sulks. I rekindle a waning argument with the telephone company, then cut my losses and lie down, given over to whatever is in the air. To live with the Santa Ana is to accept, consciously or unconsciously, a deeply mechanistic view of human behavior. ...[T]he violence and the unpredictability of the Santa Ana affect the entire quality of life in Los Angeles, accentuate its impermanence, its unreliability. The wind shows us how close to the edge we are.

Temperatures quickly rise past the boiling point of water, making the Earth's surface uninhabitable. Humanity is able to survive at first by moving underground, but eventually even this fails as the sun ages rapidly. It actually becomes so hot at one point, that for a while there's no longer enough oxygen for fire, and anything made of concrete is destroyed because the water it was created with vaporizes from the inside. By the time the oxygen does come back, Earth's temperature is thousands of degrees, which straight-up melts even hardy structures like the Pyramids and Stonehenge.

    Real Life 
  • One study showed that incidence of mental disorders with violent presentations increased when the temperature rose above 80 degrees Fahrenheit / 26.6 °C. Also, the FBI found an average increase of between 35-40% in the murder rate in urban areas from February to July over a span of five years of records.
    • Another study shows that with each degree of temperature rise, violence increases by up to 20%.
  • Summer heat is frequently cited as a contributing factor to urban riots. For instance, the disturbances in Watts (1965) and in Newark and Detroit (1967) all took place during periods of higher-than-normal temperatures in those cities. And it was 90°F / 32.2 °C in April when the 1992 Rodney King riots in Los Angeles started.
  • As in 1776 above, it was unbearably hot in Philadelphia near the end (May-July, 1776) of the Second Continental Congress, during which the American Declaration of Independence was drafted and voted on. It would also have been incredibly muggy: Philadelphia, being in the Delaware River valley, is very humid, and various features of geography give it very still air, as well.
  • The 2003 Big Blackout in the northeastern U.S. and parts of Canada came on a blisteringly hot August day, especially in New York City. Think of the people stuck in the subways and elevators, where it would be even hotter...
  • During the summer of 1977, described as the "summer that New York lost its mind", temperatures were skyrocketing, corruption was rampant, and the Serial Killer Son of Sam had made the city his personal hunting ground. A Big Blackout that July capped everything off, leading to riots and looting—it took decades for some neighborhoods to recover.
  • The summer of 2011 was an aversion to the "heat waves cause crime" trope. Temperature records were broken all across the U.S. with many cities reporting 50+ (and even 90+) days of serial temperatures over 100°F / 37.7 °C. Several states also recorded the hottest months of June, July, August, and September ever, with similar drought records being set. Despite this, reported crime was actually lower compared to years previous. Presumably, it's not worth the energy to commit high crime in sizzling temperatures.
  • The period of late 2012 - early 2013 is often referred to in Australia as the "Angry Summer", where over 123 weather records were broken in Australia's hottest summer on average, and may have contributed to the rise in violence (particularly gang-related incidents in Sydney) throughout the rest of the year. It also brought about nature's anger with bushfires across Tasmania and floods in coastal Queensland.
    • The Cronulla riots in Sydney in 2005 took place in December, during the Southern Hemisphere summer.
    • In 2017, power was intentionally cut for thousands of homes throughout Adelaide in the middle of a major heatwave to save energy. Despite lasting for less than an hour, the entire city was furious at the government for the cut, as well as not keeping enough power stations and making it clear that they did not learn from the infamous statewide blackout in September 2016. The reigning government lost at the following election, with the power cut as a cited reason.
    • Late 2019 brought serve heatwaves across Australia that lead to the Black Summer bushfires. People across the nation and even in New Zealand could smell smoke from hundreds of miles away. Despite calls for them to be cancelled, major New Years' fireworks shows went on ahead, with extra firefighters on standby in the event of a spark, which happened in South Australia after the 9pm fireworks caused a fire near Adelaide Oval.
  • The heat wave that affected Europe in 2003 deserves mention as it was the strongest one recorded since at least 1540, claiming 70,000 deaths and hitting France especially hard.
  • Spain suffered in July 2015 the longest-lasting heat wave since registers exist, with three hot weeks of temperatures above or around 95°F / 35 °C even in those regions where summer temperatures are far milder.
  • A particularly bad heat wave hit much of the Pacific Northwest, including Washington, Oregon, and the Canadian province of British Columbia, in the summer of 2021. Lytton, a small town in British Columbia, broke the all-time hottest temperature record in Canada for three consecutive days (culminating with an all-time high of 49.6 °C (121.3 °F)) on June 29...and then a day later, was largely destroyed by an extremely fast-moving wildfire.
