The UK could be set to have had its warmest year on record, forecasters say.
The Met Office said that 2025 is on track to become one of the UK's warmest years, possibly surpassing 2022 to take the top spot.
So far, the average annual temperature is tracking at 10.05C, ahead of the previous record of 10.03C set in 2022.
A forecasted cold spell over Christmas means the final figure is not yet confirmed.
If confirmed, 2025 will be only the second year in observational records where the UK's annual mean temperature has topped 10C.

Four of the last five years will then appear in the top five warmest years since records began in 1884, with all of the top 10 warmest years occurring in the last two decades.
A new record has been previously set for the UK annual mean temperature five times this century - in 2002, 2003, 2006, 2014 and 2022.
"At this stage it looks more likely than not that 2025 will be confirmed as the warmest year on record for the UK," said Mike Kendon, a senior scientist at the Met Office.
"In terms of our climate, we are living in extraordinary times.
"The changes we are seeing are unprecedented in observational records back to the 19th century," he added.
