June 2025 was Earth\u2019s third-warmest June in analyses of global weather data going back to 1850, NOAA\u2019s\u00a0National Centers for Environmental Information<\/a>, or NCEI, reported July 10.\u00a0NASA<\/a>\u00a0and the European\u00a0Copernicus Climate Change Service<\/a>\u00a0also rated June 2025 as the third-warmest June on record, behind only 2024 and 2023. Data from the\u00a0Japan Meteorological Agency<\/a>\u00a0and Berkeley Earth were not available at the time of this writing.<\/p>\n

Global land areas had their sixth-warmest June on record in 2025, and global oceans had their third-warmest June, according to NOAA. Europe and Asia had their fifth-warmest June on record; North America, its eighth-warmest; Africa, its ninth-warmest; South America, Oceania, the Arctic, Antarctic, and the Caribbean and Hawaiian regions also recorded above-average temperatures for June, but did not record top-10 ten warmest Junes on record.<\/p>\n

According to NOAA<\/a>, the year-to-date-period (January-June) has been the second-warmest on record for the globe, only 0.08 degree Celsius (0.14\u00b0F) cooler than 2024. NOAA gave a greater than 95% chance that 2025 would wind up as a top-four warmest year on record; a 3% chance of it being the second-warmest year on record; and a less than 1% chance of being the warmest year on record.<\/p>\n

Seventh-warmest June for the contiguous U.S.<\/p>\n

During June, the average temperature in the contiguous U.S.\u00a0was the seventh-warmest since records began in 1895. Seventeen states had a top-ten hottest June; no states had a below-average June temperature. Six of the nation\u2019s seven hottest Junes have all occurred since 2015, and the year to date is the 14th warmest in the 131 years of the NOAA database. Washington, Oregon, and Idaho had a top-ten driest June on record.\u00a0<\/p>\n

June state records and all-time local records set during June 2025 Northeast U.S. heat wave<\/p>\n

The standout weather event for the month was the powerful heat wave of June 22-25, which was especially notable for its early-in-the-season intensity as it moved from the Midwest into the Northeast. Minneapolis, Chicago, Detroit, and New York Central Park were among the locations that experienced their warmest daily low temperatures ever recorded so early in summer. On June 24, temperatures\u00a0near or above 100\u00b0F covered most of the Interstate 95 corridor from Washington, D.C., to Portland, Maine. Many state June high temperature records were set on June 24, 2025, and several all-time (any-day) records were set or tied on June 23-24, as detailed in the list below. This list was compiled\u00a0by weather records expert Chris Burt, author of \u201cExtreme Weather,\u201d who has carried out multiple evaluations of record high temperatures (such as the \u201cdethroned\u201d world record at\u00a0El Azizia, Libya<\/a>, and another still officially recognized but problematic at\u00a0Death Valley, California<\/a>).\u00a0<\/p>\n

U.S. tornadoes<\/a>\u00a0in June numbered 252, with four being EF2 or stronger. The preliminary total of 1,324 U.S. tornadoes observed from January 1 to July 8\u00a0ranks<\/a>\u00a0as the second-highest year-to-date total since 2010, behind 2011 (1,919). June had six tornado deaths in the U.S., bringing the tornado death toll for the year so far to 68.<\/p>\n

Neutral conditions (neither La Ni\u00f1a nor El Ni\u00f1o) prevail<\/p>\n

The weak La Ni\u00f1a conditions in the Eastern Pacific that began in December 2024 ended in March, and neutral conditions are now present, NOAA reported in its July\u00a0monthly discussion\u00a0<\/a>of the state of the El Ni\u00f1o\/Southern Oscillation, or ENSO. ENSO is a recurring ocean-and-atmosphere pattern that warms and cools the eastern tropical Pacific through El Ni\u00f1o and La Ni\u00f1a events that last from one to three years. According to NOAA\u2019s July forecast, ENSO-neutral conditions are likely (56% chance) during August-October 2025. Thereafter, chances of La Ni\u00f1a conditions increase into the fall and winter 2025-26, but remain nearly equal to ENSO-neutral. For the upcoming Atlantic hurricane season (August-September-October), the\u00a0June 20 forecast<\/a>\u00a0from the\u00a0Columbia University International Research Institute for Climate and Society\u00a0called for a 32% chance of La Ni\u00f1a, a 59% chance of ENSO-neutral, and a 9% chance of El Ni\u00f1o. El Ni\u00f1o conditions tend to suppress Atlantic hurricane activity through an increase in wind shear, but La Ni\u00f1a conditions tend to have the opposite effect.<\/p>\n

While El Ni\u00f1o events often last only one year (usually from northern fall to northern spring, as in 2023-24), La Ni\u00f1a events often restrengthen or recur across two or even three years in a row, as was the case from mid-2020 to early 2023.\u00a0Over the last two decades<\/a>\u00a0(2005-2024), the peak three months of hurricane season have included five El Ni\u00f1o periods, seven La Ni\u00f1a periods, and eight neutral periods.<\/p>\n

Arctic sea ice: 2nd-lowest June extent\u00a0on record<\/p>\n

Arctic sea ice in June 2025 tracked at record-low levels from June 20-26, and ended up with the second-lowest June extent in the 47-year satellite record, slightly behind only 2016, according to the\u00a0National Snow and Ice Data Center<\/a>, or NSIDC. The Arctic had its 14th-warmest June on record in 2025.<\/p>\n

Antarctic sea ice extent<\/a>\u00a0in June was the third-lowest in the 47-year satellite record. Only 2023 and 2024 had lower June extents. The Arctic had its 28th-warmest June on record in 2025.<\/p>\n

Sea ice will be more difficult to track beginning August 1, as the Department of Defense announced that they will no longer be sharing data from the SSMIS instrument on their sea ice monitoring satellites, because of a \u201csignificant cybersecurity risk\u201d. These satellites are the primary source of sea ice information for the NSIDC and have been sending data since 1987. There is an alternative source of data (the AMSR2 instrument on a Japanese satellite), but it is uncertain how long it might take for NSIDC data products to shift to using the Japanese satellite data. In addition, budget cuts are hitting NSIDC, which said<\/a> today, \u201cWith budget cuts from NASA for\u00a0Sea Ice Today, we will no longer write mid-month analyses in the months leading up to the Arctic sea ice minimum.\u201d<\/p>\n

The loss of the SSMIS data is also a huge blow to hurricane forecasters, and the timing of this data shut off is inexplicable for the reasons given, as explained in a post from Michael Lowry linked below.<\/p>\n
