Samantha Burgess, strategic lead for climate at the European Centre for Medium-Range Weather Forecasts which runs C3S, said: “January 2025 is another surprising month, continuing the record temperatures observed throughout the last two years, despite the development of La Nina conditions in the tropical Pacific and their temporary cooling effect on global temperatures.
World sees record hot January with temperatures 1.75C above pre-industrial era Last month was the hottest January on record, despite an emerging “La Nina” weather pattern that cools global temperatures, scientists have said.
Temperatures were below average in the central Pacific but close to or above average in the eastern Pacific – suggesting a slowing or stalling of the move to La Nina conditions, while sea surface temperatures were unusually high in many other oceans and seas.
The data shows sea surface temperatures outside the polar regions averaged 20.78C, making it the second hottest January after last year’s record.
It makes it the 18th month in the last 19 for which average global air surface temperatures were more than 1.5C above what they were before the industrial era.
