Global Temperatures

The year 2024 was the warmest year since global records began in 1850 at 1.29°C (2.32°F) above the 20th century average of 13.9°C (57.0°F). This value is 0.10°C (0.18°F) more than the previous record set last year. The ten warmest years in the 175-year record have all occurred during the last decade (2015–2024). Of note, the year 2005, which was the first year to set a new global temperature record in the 21st century, is now the 13th-warmest year on record. The year 2010, which had surpassed 2005 at the time, now ranks as the 12th-warmest year on record.

The previous year’s record warmth was due in part to the presence of the warm phase of El Niño Southern Oscillation (ENSO), which began in June 2023 and continued until May of this year. A transition to ENSO-neutral conditions took place at that time and persisted through November before the cold phase of ENSO (La Niña) emerged in December, according to NOAA’s Climate Prediction Center. As seen in the image below, global temperatures tend to be cooler during periods of ENSO-neutral conditions and even cooler during La Niña. Although ENSO-neutral conditions were present beginning in May 2024, monthly global temperature records continued to be set or tied through August 2024.


Global monthly temperature anomalies, with ENSO status

In total there were 14 straight months of record-breaking global temperatures from June 2023 through July 2024. The July global temperature value was likely the warmest of all months on record. Monthly temperatures beginning in September and for the remainder of the year were slightly below the 2023 records. The peristence of record and near-record monthly temperatures throughout the year brought the 2024 annual temperature to its new record, continuing a warming trend that has resulted in an average rate of increase of 0.06°C (0.11°F) per decade since 1850 and more than three times that rate (0.20°C / 0.36°F) since 1975.

Global ocean temperatures in 2024 were also noteworthy, reaching 15-straight months of record-breaking temperatures, from April 2023 through June 2024. Each month from January through April each exceeded the previous monthly records by at least 0.15°C (0.27°F).

In the Arctic, 2024 was the second-warmest year on record, 2.71°C (4.88°F) above average, and 0.24°C (0.43°F) less than the record set in 2016. Arctic sea ice extent reached reached its minimum for the year in September; the seventh lowest minimum on record. Since 2007, the Arctic sea ice minimum has dropped below 5 million square kilometers (1.93 million square miles) every year, except in 2009, 2013, and 2014, when the extent barely crossed the 5 million square kilometer mark. According to the National Snow and Ice Data Center, this persistent new normal, and the related losses of most of the old and thick ice, are prominent characteristics of the new, warmer Arctic.

The 2024 Northern Hemisphere surface temperature also was warmest on record, 1.67°C (3.01°F) above average. The Northern Hemisphere winterspring, and summer seasons were each warmest on record; 1.84°C (3.31°F), 1.61°C (2.90°F), and 1.52°C (2.74°F) above average, respectively. Meanwhile, the Southern Hemisphere summer (December–February), autumn (March–May), and winter (June–August) were each warmest on record and the year as a whole was record warmest, with a temperature that was 0.90°C (1.62°F) above the 20th century average.

Precipitation

Precipitation data from the Global Historical Climatology Network (GHCN) shown in the maps below are augmented by data with greater spatial coverage from the Global Precipitation Climatology Project (GPCP). The GHCN and GPCP map of 2024 precipitation anomalies show areas that were unusually wet for the year contrasted in other areas by drier-than-normal conditions.

Below-average annual precipitation occurred in areas that included much of Canada extending into parts of the western U.S. and Mexico. The most expansive and severely drier-than-average conditions occurred across much of South America, most notably in large parts of Brazil and neighboring Bolivia and Peru where in many locations the driest to near-driest year on record occurred. Other drier-than-average areas included southern and southwestern Africa, where record to near-record dryness occurred across much of Zimbabwe and Zambia as well as parts of Cameroon, the Republic of the Congo, and Gabon. The combination of record and near-record temperatures along with the lack of precipitation led to severe drought in many areas. Parts of eastern Ukraine and neighboring Russia also were notably drier-than-average in 2024.

In contrast, anomalously high precipitation fell in areas that included a large part of the African Sahel, where record and near-record wet conditions were widespread. Central Asia including much of Kazahkstan and central Russia had widespread much-above-average to record-wet conditions, as well as eastern Mongolia and northeast China. Parts of these areas were hit by periods of heavy rain and flooding as noted in the continent summaries below. A number of other areas with above-average precipitation in 2024 had flooding and other impacts associated with tropical systems. These included the Deep South and southeastern U.S., which were severely affected by Hurricanes Beryl, Debby, Francine, Helene, and Milton. Other areas widely affected by tropical cyclones included Tanzania, Kenya, Bangladesh, India, Vietnam, the Philippines, Japan, eastern China, Indonesia, Malaysia, and parts of northern Australia.


January-December 2024 Land-Only Precipitation Anomalies


January-December 2024 Land-Only Precipitation Percent of Normal

North America

  • A series of atmospheric river events brought heavy rain and snow to parts of California in February, causing significant flooding, powerful winds, landslides, and power outages.
  • Hurricane Beryl became the first Category 4 hurricane observed in the Atlantic Ocean during the month of June. It made landfall in Carriacou, Grenada causing extensive damage across the Windward Islands before moving further westward and strengthening into the earliest Category 5 hurricane on record in the Atlantic.

  • Heavy rain in northeast China produced flooding that led to more than a dozen deaths and extensive damage to infrastructure in August.
  • Heavy rain associated with Tropical Storm Trami in October led to flooding and landslides in the Philippines that damaged infrastructure and led to mass evacuations and more than 125 deaths reported.
  • Typhoon Yagi peaked as a Category 4 equivalent and was one of the strongest typhoons on record to strike Northern Vietnam and southern China. It resulted in widespread damage and hundreds of fatalities.

Oceania

  • Tropical Cyclone Megan made landfall in Northern Territory, Australia in March causing significant damage to ports and major flooding.
  • Nationally-averaged rainfall for Australia was 28% above the 1961–1990 average, making it the eighth-wettest year since national records began in 1900.

Snow and Ice

Snow cover data are provided by the Rutgers University Global Snow Laboratory. The period of record is from 1967–2024 for a total of 58 years. The sea ice extent data are provided by the National Snow and Ice Data Center (NSIDC) and are measured from passive microwave instruments onboard NOAA Satellites. The sea ice extent period of record is from 1979–2024 for a total of 46 years.

Snow Cover

Northern Hemisphere snow cover extent averaged 9.2 million square miles in 2024, which was slightly below average. Monthly extent ranged from 18.1 million square miles in January to just under 1.0 million square miles in August, both of which were slightly below average.

Sea Ice Extent

Arctic sea ice extent averaged 4.03 million square miles in 2024, the seventh lowest on record. The maximum extent in March was 5.74 million square miles, which ranked 15th lowest, while the monthly minimum extent in September was 1.69 million square miles, which ranked sixth lowest. The minimum for the year was reached in mid-September and was the seventh lowest on record.

Antarctic sea ice extent averaged 4.00 million square miles in 2024, the second lowest on record. The maximum extent in September was 6.59 million square miles, which ranked second lowest, and the minimum extent in February was 830,000 square miles, which also ranked second lowest. According to the NSIDC, Antarctic sea ice reached its minimum extent for the year, at 1.99 million square kilometers (768,000 square miles) on February 20, 2024. This tied with 2022 for second lowest on record, behind 2023. It was the third consecutive annual minimum below 2 million square kilometers (772,000 square miles).


Ocean Heat Content

Ocean Heat Content (OHC) is essential for understanding and modeling global climate since > 90% of excess heat in the Earth’s system is absorbed by the ocean. Further, expansion due to increased ocean heat contributes to sea level rise. Change in OHC is calculated from the difference of observed temperature profiles from the long-term mean.
