Heat Waves Knowledge Quiz – When Heat Becomes Dangerous

A heat wave is a stretch of unusually hot weather that lasts several days. Many are caused by heat domes, where high pressure traps warm air and clear skies let the Sun bake the ground day after day.

Humidity makes heat more dangerous by reducing the body's ability to cool through sweat. Cities trap extra heat in concrete and asphalt, creating urban heat islands. Heat waves are among the deadliest weather events, as shown in Europe in 2003.

Heat waves are becoming more frequent and intense with climate change, breaking records in places like the UK and Canada. Staying hydrated, finding shade or air conditioning and checking on older neighbors can save lives.
