In May 2025, it is the second Woodster on Earth in the global weather data of the NOAA's National Center for Environmental Information (NOAA) reported on June 12. May 2025 is the second month of the past 23 months, with the global average air temperature being no According to European Copernicus climate change services, over 1.5 degrees Celsius is higher than the industrialization level. This level has been exceeded before the last 23 months, just five months (January to March 2016 and January to February 2020).
According to NOAA, the global land region has a second warm May in 2025, and the global ocean has a second warm May. Third place with record in Asia and South America. North America is the sixth place; Africa, its seventh weapon; Europe, Oceania and Antarctic are likely to be higher than average, but their May temperatures are not ranked among the 10 warmest Metz ever. The northern hemisphere snow cover in May 2025 is 14Th– Since 1967.
According to NOAA, year to date (January to May) has been the second global temperature record, second only to 2024. NOAA gives >99.9% chance, and 2025 will be the highest-ranking year on record. There is a 23% chance of recording the second year; and there is less than 1% chance of recording the warmest year.
The second warmest spring in the world and continuous United States
During the 2025 Meteorological Spring (March to May) in the Northern Hemisphere, there is a second record of temperature worldwide. Only the land surface temperature in the world is recorded from March to May
The continuous U.S. average temperature in the spring was 3.2°F (1.8°C), making it the second Fahrenheit spring in the 131-year record. North Carolina recorded its second warmer spring, while Georgia, Louisiana, Maryland, Mississippi and Virginia all matched or surpassed their third round of spring.
In May, the continuous average temperature in the United States ranked the highest third in the historic Mays, extending into 1895. May was the wettest in May in Alabama, while Maryland, Pennsylvania, Rhode Island and Vermont each recorded the second wet.
The U.S. tornado number in May was 333, with 16 of them being EF2 or stronger. From January 1 to June 9, the preliminary total of tornadoes in the United States was 1,113 tornadoes, the third highest annual total since 2010, behind only 2011 (1,736) and 2024 (1,175). 27 people died in the United States in May, killing 62 tornadoes this year.
Neutral conditions
NOAA reported in a monthly discussion on the Elniño/Southern oscillation state or ENSO in June that LaNiña conditions in the eastern Pacific are weaker and have ended in March and now neutral conditions exist. ENSO is a recurring ocean and atmospheric pattern that warms and cools the eastern tropical Pacific region through the El Niño and events of La Niña for one to three years. According to NOAA's June forecast, ENSO neutral conditions may be (82% chance) as of August 2025, but in the upcoming Northern Hemisphere winter we may be stuck in the LaNiña event, with a 41% chance of LaNiña and a 48% chance of LaNiña, with a 48% chance of prevalence between December and December and December. For the upcoming Atlantic hurricane season (August to September to October), the forecast from Columbia University’s International Institute for Climate and Social Sciences requires LaNiña to have a 31% chance, ENSO neutral 54% chance, and ElNiño has a 15% chance. Elniño conditions tend to suppress Atlantic hurricane activity by increasing wind shears, but LaNiña conditions tend to have the opposite effect.
While El Niño events often last only one year (usually from northern fall to northern spring, as in 2023-24), La Niña events often restoring or recur across two or even three years in a row, as was the case from mid-2020 to early 2023. Over the last two decades (2005-2024), the peak three months of hurricane season have included five El Niño periods, seven La Niña periods, and eight neutral period.
Arctic Sea Ice: Seventh Lowest Possible Record
According to the National Snow and Ice Data Center (NSIDC), the Arctic sea ice in May 2025 is at the seventh highest range in 47-year satellite records. The Arctic has a record on the fourth tour in 2025. The record heat wave in Greenland in May caused an unprecedented melting of the island's ice sheet (see Skeet above). According to Friederike Otto of the World Weather Attribution Organization, there is no human-induced climate change, such an event will be “basically impossible”.
The Antarctic sea ice range in May was the fifth lowest in 47-year satellite record. Antarctic temperatures above average in May, but there was no top 10 warmest Metz.
