a period of excessive heat lasting two days or more that leads to illnesses and other stresses on people with prolonged exposure to these conditions
a prolonged period of excessive heat and humidity
a period of time which consists of more than three days of maximum temperatures at or above 32 C.
The definition varies depending on the region. In the Northeast a heat wave is defined as a period where the daytime maximum temperature equals or exceeds 90 degrees for three consecutive days or more.
Long lasting period with extremely high surface temperature (in EM-DAT, « heat wave » is a disaster subset of disaster type « extreme temperature »).

A heat wave is a disaster characterized by heat which is considered extreme and unusual in the area in which it occurs. Heat waves are rare and require specific combinations of weather events to take place, and may include temperature inversions, katabatic winds, or other phenomena. The worst heat wave in recent history was the European Heat Wave of 2003.
(Also called hot wave, warm wave.) A period of abnormally and uncomfortably hot and usually humid weather. To be a heat wave such a period should last at least one day, but conventionally it lasts from several days to several weeks. In 1900, A. T. Burrows more rigidly defined a "hot wave" as a spell of three or more days on each of which the maximum shade temperature reaches or exceeds 90°F. More realistically, the comfort criteria for any one region are dependent upon the normal conditions of that region. In the eastern United States, heat waves generally build up with southerly winds on the western flank of an anticyclone centered over the southeastern states, the air being warmed by passage over a land surface heated by the sun. See also hot wind. Ward, R. de C., 1925: The Climates of the United States, 383–395.
A period of abnormally and uncomfortably hot weather. It could last from several days to several weeks. The Weather Channel uses the following criteria for a heat wave: a minimum of ten states must have 90°F plus temperatures and the temperatures must be at least five degrees above normal in parts of that area for at least two days or more.
A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity.
