Heatwave will ease with thundery breakdown for some (2024)

FAQs

What is the best way to survive heatwave? ›

Keep cool: use air conditioning or a fan, wear light and loose-fitting clothing, and keep skin wet, using a spray bottle or damp sponge and by taking cool showers. Stay hydrated: during days of extreme heat, keep drinking water before you feel thirsty, especially if outdoors or performing physical activity.

Heat Safety Resources

A heat wave is a period of abnormally hot weather generally lasting more than two days. Heat waves can occur with or without high humidity.

Heat can exacerbate drought, and hot, dry conditions can in turn create wildfire conditions.

Yes, but not for too long. Some people like their saunas 100° even though that is quite hot. As long as you've drank enough, you could survive for maybe 15 minutes without damage. Any longer would probably cause harm but would only be lethal after 45min or more.

Warm temperatures allow the atmosphere to hold more humidity, and that humidity is a prerequisite for building clouds—specifically, the tall, menacing cumulonimbus clouds that produce thunder and lightning.

The National Oceanic and Atmospheric Administration projects that “it is virtually certain” that 2024 will rank among the 10 warmest years on record and gives 2024 a 55 percent chance of topping 2023 as the warmest year.

July 1743 heatwave in China - Beijing reached 44.4 °C (111.9 °F) on July 25, higher than any modern records. 11,400 people reportedly died. July 1757 heatwave – Europe, hottest summer in Europe since 1540 and until 2003. 1896 Eastern North America heat wave – killed 1,500 people in August 1896.

Externally, the upper limit of the human body's thermoneutral zone—the ambient temperature range in which the body can maintain effectively maintain its temperature and equilibrium—likely falls somewhere between 104 and 122 degrees Fahrenheit, according to a 2021 study published in Physiology Report.

Take Steps to Stay Cool

If your area is experiencing extreme heat, stay in air-conditioned spaces as much as possible, especially during the warmest parts of the day, typically 10 a.m. to 5 p.m. (PDF). And don't underestimate how hot it can get indoors without AC.

A range of factors — including general warming due to human-caused climate change, the El Niño climate pattern, record-low Antarctic sea ice and others — contributed to 2023's record-breaking heat, but they don't tell the full story. Schmidt said more work has to be done to fully understand why the year was so hot.

Heat waves begin with a high-pressure system (also known as an anticyclone), where atmospheric pressure above an area builds up. That creates a sinking column of air that compresses, heats up, and oftentimes dries out.

But can fires really ignite spontaneously at high air temperatures? High temperatures alone do not trigger forest fires. The combination of intense heat and prolonged drought only sets the stage for fires to start more easily - especially when an ignition source is present.

At 50 degrees heat and 50% relative air humidity, the rise in metabolic rate was accompanied by a 1 degree rise in core temperature, suggesting that this is the point where the body can no longer dissipate heat. If you feel dizzy, sick or faint in the heat, don't push through– find a cool, shaded place and drink water.

Keeping a bucket containing water will certainly cool down the surrounding air. * The water will evaporate over time - in order to move from liquid to gas it needs to gain energy, and it does this by taking some of the heat energy out of the surrounding air.

Have cold food and drinks, avoid alcohol, caffeine and hot drinks, and have a cool shower or put cool water on your skin or clothes. Keep your living space cool. Close windows during the day and open them at night when the temperature outside has gone down. Electric fans can help if the temperature is below 35 degrees.
