A series of new records for high temperature were broken in the UK in 2019, concluding a record-breaking decade, the Met Office has said.

The last decade was the second hottest in the past 100 years in the UK, with eight new high-temperature records set.

Four new UK records were set last year alone, including the highest winter and summer temperatures ever recorded.

Dr Mark McCarthy, head of the National Climate Information Centre, said it was “a consequence of our warming climate”.

Record-breaking 2019

Last year, a maximum of 21.2C was reached on 26 February, in London – the hottest February day ever recorded.

On 25 July, temperatures then reached 38.7C in Cambridge – the UK’s highest-ever recorded temperature.

The third record-breaker for 2019 was for the highest daily minimum temperature in February – a temperature of 13.9C recorded on 23 February in the Scottish Highlands.

The hottest December day is also likely to have been exceeded last week, with a provisional temperature of 18.7C recorded in the Highlands of Scotland on 28 December – although the figure still needs to be validated.

Overall, the UK was warmer, wetter and sunnier than average in 2019, the Met Office said.

It said 2019 was provisionally the 11th warmest year on record, with a mean average temperature of 9.42C, putting it just outside the top 10 – all of which have all occurred since 2002.

Across the decade – from 2010 to 2019 – other record monthly temperatures were recorded on 1 October 2011 in Kent (29.9C) and 1 November 2015 in Ceredigion (22.4C).

Record highest daily minimums were reached on 25 January 2016 in County Londonderry (13.1C) and 19 April 2018 (15.9C) in Greater London.

Also in the record books was the coldest March day on record, when the “Beast from the East” struck in 2018.

However, Dr McCarthy said it was “notable how many of these extreme records have been set in the most recent decade and how many more of them are reflecting high rather than low-temperature extremes”.

He warned the trend was likely to continue, adding: “We would expect these sorts of records subsequently to be broken in the future.”

He said: “We are expecting to see an increase in winter rainfall, so wetter winters and drier summers – but we could still experience some dry winters and wet summers.”

A government spokesman said climate change was a “national priority” and it was committed to increasing the momentum around environmental action.

“Since 1990, we have reduced our emissions by over 40% while growing the economy by over two thirds.

“But we are determined to do more to increase the momentum and drive ambitious action both in the run up to and at this year’s COP26 talks in Glasgow.”
