June in Hong Kong ranked fourth warmest on record.

June 2023 in Norway ranked fourth warmest on record.

The Netherlands recorded its warmest June on record.

Portugal had its fifth-warmest June on record.

With an average temperature 2.5☌ above average, the United Kingdom had its warmest June since records began in 1884.

San Juan, Puerto Rico recorded its warmest June on record.Īfrica had its third-warmest June on record (tied with 2017), while South America, Europe, and Asia (tied with 2010) each had their fourth-warmest June.

June 2023 Blended Land and Sea Surface Temperature PercentilesĪ smoothed map of blended land and sea surface temperature anomalies is also available. Less than 1% of the world's surface had a record-cold June. Sea surface temperatures were near to below average over parts of the central-eastern and southeastern Pacific and the northwestern Atlantic Ocean.

Temperatures were near to cooler than average across parts of the U.S., Greenland, western Russia, Pakistan and northern India, western Australia and Chad and northeastern Nigeria. Combined, record-warm temperatures covered just over 8.6% of the world's surface this month - the highest June percentage on record. Parts of the eastern Atlantic, the southwestern Pacific, the southern Indian Ocean, as well as parts of northern Canada, Mexico, western Europe, and southern Africa saw record-warm June temperatures. Sea surface temperatures were above average across much of the northern, central and western Pacific, the Atlantic and the Indian Ocean. Parts of northern and southern North America, Oceania, Antarctica and the Arctic also experienced warmer-than-average temperatures this month. Temperatures were above average throughout most of South America, Europe, Africa and Asia.

June heat was not limited to the ocean surface the Southern Hemisphere had its warmest June on record and the Northern Hemisphere tied 2019 for its warmest June. Globally, June 2023 set a record for the highest monthly sea surface temperature anomaly of any month in NOAA's 174-year record. Weak El Niño conditions that emerged in May strengthened, as above-average sea surface temperatures returned to the equatorial Pacific Ocean. Global ocean surface temperature hit a record high for June, which marks the third-consecutive month where ocean surface temperatures broke a record. June 2023 marked the 47th consecutive June and the 532nd consecutive month with global temperatures, at least nominally, above the 20th-century average. The Junes of 2015–2023 rank among the ten warmest Junes on record. This marked the first time a June temperature exceeded 1☌ above the long-term average. The June global surface temperature was 1.05☌ (1.89☏) above the 20th-century average of 15.5☌ (59.9☏). June 2023 set a record as the warmest June for the globe in NOAA's 174-year record. Precise of the climate system, and it is publicly available through The most current reconstruction analysis is always considered the most representative and These factors, together, mean thatĬalculations from the past may be superseded by the most recent data and can affect the numbers reported in the

The new historical data can bring about updates to previously reported values. Meaning that the entire period of record is recalculated each month with new data. NOAAGlobalTempv5.1.0 is a reconstructed dataset, Updated in 2023, uses comprehensive data collections of increased global area coverage over both Preliminary data generated from authoritative datasets of temperature observations from around the globe. NOAA's National Centers for Environmental Information calculates the global temperature anomaly every month based on Might differ slightly from what was reported previously, the main conclusions regarding global climate change are This new version includes complete global coverageĪnd an extension of the data record back in time an additional 30 years to January 1850. (NOAAGlobalTemp) dataset version 5.1.0 replaced version 5.0.0.
