Ireland set a record daily maximum temperature of 25.9 degrees for April.

That is according to the EU's Copernicus Climate Change Service, which found the European-average temperature for April 2025 was 1.01 degrees above the 1991-2020 average for April, making it the sixth-warmest April on record for Europe.

That makes it cooler by 0.91 degrees than the warmest April back in 2018.

The European-average temperature for April 2025 was 1.01 degrees above the 1991-2020 average for April, making it the sixth-warmest April on record for Europe.

Globally, April 2025 was 0.60 degrees warmer than the 1991-2020 average for April, with an absolute surface air temperature of 14.96 degrees.

The second-warmest April on record, 0.07 degrees cooler than the warmest April in 2024, and 0.70 degrees warmer than the third warmest in 2016

It was 1.51 degrees warmer than an estimate of the pre-industrial April average for 1850-1900.

The last 22 months have also each been at least 0.60 degrees warmer than the 1991-2020 average for the month in question, a level reached only twice previously, in February and March 2016.

Averaging over 12-month periods smooths out shorter-term variations in regional and global-average temperatures.

Surface air temperatures were predominantly above the 1991-2020 climatological values across Europe in April 2025.

The largest warm anomalies were recorded over eastern Europe and western Russia and Kazakhstan. Norway also had notably warmer-than-average conditions.

The United Kingdom recorded its third-warmest April on record, with the daily maximum temperatures being particularly above average – at 2.8 degrees – for the United Kingdom as a whole.

In contrast, Türkiye, eastern parts of Bulgaria and Romania, the Crimean Peninsula, northern Fennoscandia and northwest Russia had colder-than-average temperatures.

Outside Europe, temperatures were most above average over the Russian Far East and in a large part of west central Asia.

This was reflected by the United Arab Emirates having its warmest April on record and an average daily high of 42.6 degrees and Pakistan having its second-warmest April in 65 years.

China also recorded its second-warmest April since 1961.

The United States, Mexico, and large parts of Canada experienced mostly above-average temperatures. Australia had mixed conditions, with warmer-than-average temperatures in southern and western regions, where Victoria had its warmest April since 1910, and cooler-than-average temperatures in northern areas.

Most of Africa generally had above-average temperatures, although there were pockets of below-average conditions.

Cooler-than-average temperatures also occurred across southern South America, in eastern Canada in the Great Lakes region and over the Hudson Bay, and across northeastern Greenland and Svalbard.

Antarctica saw above-average temperatures across the Antarctic Peninsula and West Antarctica, while there were below-average temperatures in East Antarctica
