A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. While definitions vary, a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area. The term is applied both to routine weather variations and to extraordinary spells of heat which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, and widespread power outages due to increased use of air conditioning.

“For, ere Demetrius looked on Hermia’s eyne,
He hailed down oaths that he was only mine,
And when this hail some heat from Hermia felt,
So he dissolved, and showers of oaths did melt.”

“I sometimes compare press officers to riflemen on the Somme—mowing down wave upon wave of distortion, taking out rank upon rank of supposition, deduction and gossip.”
