Temperature
Globally, May 2025 was the second-warmest May in NOAA’s 176-year record, with a temperature 1.98°F (1.10°C) higher than the 20th-century baseline. This is 0.14°F (0.08°C) cooler than the record set last May (2024). According to NCEI’s Global Annual Temperature Outlook, it is very likely that 2025 will rank among the five warmest years on record, with less than a 1% chance of ranking as the warmest year on record.
May temperatures were above average across much of the globe’s surface, in particular across most ocean areas and parts of every continent. Warm temperature departures were most notable in northern North America, the central and southern parts of South America, the British Isles and surrounding ocean, northern and southwestern Asia and across much of the Arctic and Antarctic regions. Pockets of below-average temperatures were present across parts of Alaska, eastern Europe, India and Antarctica.
