How Britain’s temperatures have been over 75F for 46 days in a row2 min read


The top temperature in Britain has been over 75F (24C) for 46 days in a row up to and including yesterday.

Of those 46 days, some 29 have seen temperatures of at least 85F (29.4C), while ten have been at least 90F (32C). 

The hottest day of 2018 record has been broken six times within the period – including on four days in a row in June. 

The lowest reading in the 46-day period was 75.2F (24C) on July 28, while the highest was 95.2F (35.1C) two days earlier.

Here are the top temperatures recorded in Britain on each of the past 45 days: 

July 4: 84.4F (29.1C) 

July 5: 88.6F (31.2C)

July 6: 88.5F (31.4C)

July 7: 88.7F (31.5C)

July 8: 90.3F (32.4C) 

July 9: 86.9F (30.5C)

July 10: 79.3F (26.3C)

July 11: 81F (27.2C)

July 12: 79.7F (26.5C)

July 13: 82.6F (28.1C)

July 14: 85.3F (29.6C)  

July 27 – 94.5F (34.7C)

July 28 – 75.2F (24C)

July 29 – 76.3F (24.6C)

July 30 – 79.2F (26.2C)

July 31 – 78.4F (25.8C)

August 1 – 80.4F (26.9C)

August 2 – 87.1F (30.6C)

August 3 – 91.8F (33.2C)

August 4 – 85.6F (29.8C)

August 5 – 86.4F (30.2C)

August 6 – 90.5F (32.5C) 

Yesterday – 91.8F (33.2C)

This year’s run of 46 days with temperatures over 75F (24C) is unusual for Britain – but just misses out on the record.

That is held by 1995 which saw a 53-day period from July 5 to August 26 when the mercury hit at least 75F (24C).

In comparison, the famous heatwave summer of 1976 saw 15 days in a row when temperatures hit at least 89.7F (32C).
