Heat wave

A heat wave or heatwave, sometimes described as extreme heat, is a period of abnormally hot weather that lasts for multiple days. A heat wave is usually measured relative to the usual climate in the area and to normal temperatures for the season. The main difficulties with this broad definition emerge when one must quantify what the 'normal' temperature state is, and what the spatial extent of the event may or must be.

Temperatures that humans from a hotter climate consider normal can be regarded as a heat wave in a cooler area.
This would be the case if the warm temperatures are outside the normal climate pattern for that area.
