#USWeather: Over 2,800 #HighTemperature records set during #HeatWave
A week-long heat wave set over 2,800 record high temperatures in towns across the nation, with some spots measuring their hottest June or all-time temperatures.
By Jesse Ferrell & Brian Lada
Published Jun 23, 2025"A total of 955 daily high temperature records and 1,899 daily high minimum (warm night) records were tied or broken during the last week's heat wave.
"Records dating back to the 1800s were shattered as an early-summer heat wave roasted large areas of the central and eastern United States. AccuWeather RealFeel® Temperatures blew past the 100-degree mark, air conditioners were on full blast, and cities opened cooling centers to help people cope with the intense heat.
" 'This is an incredibly hot and steamy heat wave for the month of June,' AccuWeather Chief On-Air Meteorologist Bernie Rayno said.
Tuesday's heat breaks 137-year-old record
"The heat wave peaked on Tuesday, and it wasn't just the hottest day of 2025, but the hottest weather many residents in the Northeast have experienced in over a decade.
"The mercury soared to 102 degrees in Boston on Tuesday afternoon, making it the hottest day in the city since July 22, 2011, when it reached 103. Philadelphia also notched its first 100-degree day since July 18, 2012.
"In New York City, the temperature fell just shy of hitting triple digits, but the high of 99 degrees was still enough to beat the previous daily record for the date, surpassing the high of 96 degrees set on June 24, 1888. Some areas not far from Central Park, where the official weather observations for the city are taken, did manage to hit 100 degrees, including Newark (103) and John F. Kennedy International Airport (102).
"Other cities across the region that reached 100 F on Tuesday afternoon include Hartford, Connecticut; Providence, Rhode Island; Wilmington and Dover, Delaware; and Manchester, New Hampshire.
"Monthly and hourly records were also set
"Illustrating how unusual and early the heat wave was, a thermometer in #AugustaME, recorded 100 degrees, tying their all-time record high set on Aug. 5, 1955. It joined 13 other stations where the temperature had never been recorded hotter.
"Many cities had never been as hot in June as they were Tuesday. Stations reporting their hottest June temperatures on record include #NewarkNJ, at 103 (tied); #NewYorkCity (Kennedy & LaGuardia at 102 and 101, a tie); Islip, New York at 101; Portland and #BangorME, at 99 and 98, a tie; and Mount Pocono, Pennsylvania, at 93, recorded on Monday. A total of 90 stations set June records.
"The heat came early in the day, with #Philadelphia setting or tying new hourly record highs for 9 a.m., 7 a.m., and 5 a.m., and New York City (JFK Airport) notching new or tied extreme highs at 3 a.m., 8 a.m., 1 p.m., 4 p.m., and 5 p.m, according to the Iowa Environmental Mesonet. For June, Philadelphia's hourly temperatures had never been higher for all but two hours of the day.
Monday's records
"The first full week of astronomical summer wasted no time warming up, with many thermometers across the region reaching levels they haven't hit in years.
"#Baltimore's Inner Harbor was one of the hottest spots on Monday, with a high of 104 F. The high humidity and strong summer sun made it dangerously hot outside, with the AccuWeather RealFeel® Temperature topping out at 113 degrees. To put this heat into perspective, 113 degrees is the historical average high temperature in Death Valley in mid-June.
"#NewarkNJ, reached 101 degrees, breaking its daily record of 99, and #RaleighNC, tied its daily record of 100, set last year.
"Although other weather stations broke records, they were all below 100 degrees. Most notably, the temperature at Mount Pocono, Pennsylvania, rose to 93 degrees, breaking the daily record and setting June's highest reading. This was the first 90-degree day at Mount Pocono since 2013.
Sunday's records"On Sunday, three weather stations broke the high temperature records for the date. Alpena, Michigan, hit 97 degrees Fahrenheit, breaking the previous record of 93 set in 1975. In #ValleyNE, the mercury pushed up to 94 degrees, breaking the old record of 91 from 2023. And in #MarquetteMI, the old record of 90 degrees, on this date in 1995, was smashed by a reading of 93.
"But it wasn't just daily record highs. Records for warm nights were also broken at breakneck speed. Saturday night tied the all-time high minimum historical record for Green Bay, Wisconsin, at 79 degrees, previously achieved in July 4, 1897, and July 30, 1916. Wausau, Wisconsin, didn't cool below 78 degrees, which had previously happened only on July 4, 1999. The fact that these records were previously recorded in July is an indicator of how early this severe heat wave is.
"Record warm nights for June were also set at La Crosse, Wisconsin, (80 degrees) and Mason City, Iowa, (77 degrees) Saturday night.
"A total of 255 record warm nights for June were recorded over the last week, with 59 of those new records the warmest nights ever recorded at the stations."

From 2011:
In Tennessee, #HeatWaves Diminish #Nuclear Power Output
By Alyson Kenward
April 10, 2011"On July 8, 2010, as the temperature in downtown Decatur, Alabama climbed to a sweltering 98°F, operators at the #BrownsFerry #NuclearPowerPlant a few miles outside of town realized they had only one option to avoid violating their #environmental permit: turn down the reactors. For days, the Tennessee Valley Authority (#TVA), which owns the nuclear plant, had kept a watchful eye on the rising mercury, knowing that more heat outside could spell trouble inside the facility. When the #TennesseeRiver, whose adjacent waters are used to cool the reactors, finally hit 90°F and forced Browns Ferry to run at only half of their regular power output, the TVA hoped the hot spell would last just a few days.
"Eight weeks of unrelenting heat later, the plant was still running at half its capacity, robbing the grid of power it desperately needed when electricity demand from #AirConditioners and fans was at its peak. The total cost of the lost power over that time? More than $50 million dollars, all of which was paid for by TVA’s customers in Tennessee.
"The Browns Ferry nuclear plant, located on the Wheeler Reservoir along the Tennessee River near Athens, Alabama. It has three reactors, each producing about 1000 megawatts of electricity. Credit: Nuclear Regulatory Commission.
“'Last summer, the water in the Tennessee River warmed up early and stayed warm,' says TVA spokesman Ray Golden. 'When it got hot again in July and August, we were impacted by that and had to reduce power at the plant and get it from somewhere else.'
"With river water so warm, the #NuclearPlant couldn’t draw in as much water as usual to cool the facility's three reactors, or else the water it pumped back into the river could be hot enough to harm the local #ecosystem, says Golden. But for every day that the Browns Ferry plant ran at 50 percent of its maximum output, the TVA had to spent $1 million more than usual to purchase power from somewhere else, he says.
"What happened in northern Alabama last summer, at the largest of TVA's nuclear power plants, did not present a human safety concern. Operators knew there was never a risk of an explosion or nuclear meltdown, nor was there a threat of leaking radioactive material. But the prolonged spell of hot weather put the TVA at risk of violating environmental permits, with hefty fines as one consequence and potential harm to the Tennessee River ecosystem as another.
"It’s not the first time high temperatures have affected the performance of the Browns Ferry plant, and extreme heat is a growing concern for power plant operators across the #Southeast. While some nuclear plants can improve their cooling procedures to cope with the intake of warmer water, the upgrades can cost hundreds of millions of dollars and still don’t offer an indefinite defense against extreme heat. Because scientists say the Southeast (like many other parts of the world) can expect to see more frequent and intense heat waves by the end of this century, the problems for nuclear power and the people that rely on it for electricity may only be beginning.
#ExtremeHeat Limits Nuclear Energy Production
"The disaster still unfolding at Japan’s #FukushimaDaiichi nuclear plant has refocused America's attention on nuclear power, calling into question its future role in the country's energy portfolio. Many advocates of nuclear power say that we need to maintain — and even expand — nuclear power to get away from using fossil fuels, such as coal, and to help lower greenhouse gas emissions.
"But nuclear power has a paradoxical relationship with #ClimateChange. Even though it might help mitigate long-term #GlobalWarming, nuclear power is already being challenged by rising temperatures and the increasing number of heat waves around the world. Throughout the last decade, several plants have had to reduce electricity production during heat waves, just when when electricity demand typically reaches peak levels.
“'It’s a dilemma between mitigation of climate change, and adaptation to it,' says Natalie Kopytko, an energy policy doctoral student at the University of York in England. Having recently studied the ways in which climate change could have a negative impact on nuclear power, she says nuclear power is caught in the middle because it could be used to help lower greenhouse gas emissions, but global warming is making the technology less effective at providing electricity."

#Activist, 97, among dozens arrested in #Australia #climate protest
26 November 2023
Sydney, Australia, Nov 26 (EFE).- "Dozens of protesters, including a 97-year-old man, were arrested on Sunday during a #ClimateChange protest off Australia’s east coast that disrupted operations at the country’s biggest coal export port.
"#ClimateActivist group #RisingTide had organized the protest to block the traffic of coal cargo ships in the port of Newcastle since Saturday.
"The group said on its Twitter account that at least 59 people have been arrested so far.
"Since Saturday, groups of 50 to 60 protesters have been taking turns in rostered two-hour shifts getting on canoes and inflatable boats and preventing ships from leaving the port.
"Among the protesters who went out to sea was Alan Stuart, a 97-year-old religious pastor.
"Stuart said he was doing it for his grandchildren and future generations after being pulled out of his boat by the police.
"'I am doing this for my grandchildren and future generations because I don’t want to leave them a world full of increasingly severe and frequent #ClimateDisasters,' he said. 'I am so sorry that they will have to suffer the consequences of our inaction. So, I think it is my duty to do what I can and to stand up for what I know is right.'
"Rising Tide claims that the protest prevented more than half a million tonnes of coal from leaving the Newcastle port by the time the demonstration ended.
"Protesters demand that the Australian government stop all new projects that involve the use of fossil energy and confront the #ClimateCrisis more decisively.
"The climate crisis is one of the big issues of political debate in Australia, a country exposed to the effects of #droughts and #ExtremeTemperatures.
"Australia is the world’s second largest exporter of thermal coal and the largest exporter of cooking coal."
