2020 was notable for being ranked in the top ten for mean temperature, rainfall, and sunshine.
Early figures show it was the third warmest year in records dating back to 1884, beaten only by 2014 and 2006, and marginally warmer than 2011. It was also provisionally the sixth wettest year for the UK in records back to 1862, and the 8th sunniest year since 1919.
Professor Peter Stott, a Met Office research Fellow in climate change attribution, said: “All top-ten warmest years on record for the UK have occurred since 2002, and 2020 has continued to be consistent with this pattern. The general trend of warming as a consequence of climate change is clearly to be seen, not just at a global level, but in our own national temperature records too.”

For more information on the weather events of 2020, take a look back at 2020.
December 2020 was generally an unsettled and mild month, but some colder spells brought us a white Christmas with parts of Suffolk, Cambridgeshire, Yorkshire and Northumberland seeing snowfall on the 25th.
All regions of the UK received more than their expected average rainfall with some eastern areas actually exceeding their normal December rainfall by the middle of the month. South England and Wales received the most rainfall with Wales receiving 155% (256.2mm) and South England 162% (131mm). The only regions closer to normal were Western Scotland 105% (199.2mm) and Northern Ireland 113% (129mm).
It was a particularly wet month across parts of north-east Scotland and East Anglia with more than twice the normal rainfall in places. Writtle in Essex had its wettest December in 87 years while Cardiff also had a wet month with its wettest December in 72 years.
