heatwave

This term describes a specific meteorological phenomenon where temperatures remain significantly above the average for several consecutive days. It carries a strong connotation of discomfort, danger, and environmental stress, often appearing in news reports and weather warnings to signal a public health risk.

While the word is typically used to describe natural weather patterns, it is frequently paired with adjectives like "severe," "unprecedented," or "record-breaking" to emphasize the intensity of the event. It is distinct from a "hot spell," which is generally shorter and less intense.
