Heat wave

A heat wave is a prolonged period of exceptionally hot weather. In the summer of 1995, the United Kingdom was hit by a major heat wave, with temperatures rising to 90°F in London and slightly less in other areas of the country, leading Met Office to issue a Level 3 Heat-Health Alert for the first time ever.
