Highest Temperature in the UK

The highest temperature ever officially recorded in the United Kingdom is 38.5 degrees Celsius (101.3 degrees Fahrenheit) on August 10, 2003 at Brogdale, a hamlet near Faversham, Kent.

This was the first time during modern weather monitoring that the UK topped 100 degrees Fahrenheit, and it did so at several places.

Second Hottest Temperature in the UK

The August 2003 record high leapt above the previous UK record temperature of 37.1 °C (98.8 °F) set at Cheltenham on August 3, 1990. In fact, temperatures at over a dozen weather stations on August 10, 2003 beat the 1990 UK record.

The second highest temperature in 2003 was 38.1 °C (100.6 °F) which was measured at both the Kew Royal Botanic Gardens in London and at Gravesend-Broadness in Kent.

Highest Temperature in Scotland

The record-breaking day in southern England was part of a lengthy and widespread heat wave that even extended north to Scotland. The temperature on August 9, 2003 reached a record high of 32.9 °C (91.2 °F) at Greycrook, in the Scottish Borders region.

Greycrook's high nudged past the Scottish record which had stood for 95 years, although it had been equalled several times. The hottest temperature previously in Scotland was 32.8 °C (91.0 °F), first officially recorded at Dumfries on July 2, 1908.

Heat Waves in Britain

Britain reaches its highest temperatures during summer heat waves that last several days. Recent extreme hot spells occurred in August 1990, August 2003, and in June and July 1976.

For eight days in early August 2003, temperatures in the UK topped 32 °C (90 °F). The 1976 heat wave brought over two weeks of weather above 32° C (90 °F).

The 1976 event created a record high for Northern Ireland. The 1990 event reached new records for Wales and England. And the 2003 heat wave set new temperature highs for England and Scotland.

Hottest Day in London, England

London's two hottest days happened at the height of intense heat waves. On August 3, 1990, temperature records broke around the city. Then 13 years later, on August 10, 2003, the 1990 records were topped, making August 10, 2003 London's hottest day on record.
