Record-breaking heat and climate changes swept across the U.S. this past March, resulting in the most abnormally hot month of the decade; NBC reports that over 19,800 daily temperature records were broken in March across the U.S. In addition to just breaking these records, the actual increase in temperature was significantly high. The average temperature for March 2026 was 50.85 degrees Fahrenheit, measuring 9.35 F above the 20th century normal for the month of March. This surpassed the old record of 8.9 F set in March 2012.
As these conditions continue, agriculture and water supplies around the country are becoming negatively affected. The sudden drop in temperature shortly after heat waves caused some crops to frost over and become damaged. Horace Greeley AP Environmental Science teacher Dr. DeMarie explained that these crops are especially vulnerable once they begin to bloom. He stated, “It’s not good that it was heat followed by frost. The frost will impact some of the fruit production because the trees start leafing out a bit earlier, and then the frost comes and damages the flowers, especially fruit trees.” These current conditions of abnormally high temperatures accompanied by rapid changes and low precipitation can also lead to natural disasters such as flash droughts, wildfires, and flash floods. According to Drought.gov, rapid fluctuations in temperature can raise evapotranspiration (the combined process through which water moves from the Earth’s surface into the atmosphere) rates and remove available water from the landscape. As soil dries out, the land becomes less able to absorb water and more prone to those natural disasters. Increased awareness of these changing conditions and their associated risks can help communities prepare for these events. The National Oceanic and Atmospheric Administration (NOAA), recommends that people determine whether they live in an area at high risk for natural disasters, assemble a disaster supplies kit, and review what potential damages are covered by your insurance.
These precautions are becoming necessary as the effects of global warming become more prevalent in climate patterns. Climate scientists, including meteorologist Jeff Masters of Yale Climate Connections, believe that global warming from burning fossil fuels may also be contributing to the rise in climate change. Masters said, “January through March period was the driest on record for the contiguous U.S. So not only was it hot, it was record dry as well. And that’s a bad combination for water availability, for agriculture, for river levels, for navigation.”
Another possibility for these record-breaking changes is the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean, referred to as El Niño. According to NOAA , an El Niño is the result of weakening trade winds, which push warm water back east toward the west coast of the country. An El Niño begins to form when a region of the ocean rises to 0.5 or more degrees Celsius than its normal temperature. The natural climate phenomenon of El Niño typically occurs every 2-7 years and is characterized by the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean. The fluctuations caused by El Niños and rapidly changing weather fronts can lead to unusually dry and warm conditions in the northern U.S., and increase risk of flooding along the U.S. Gulf Coast.
While typical El Niño events already have significant impacts on global weather patterns, recent forecasts suggest the development of a more extreme event known as a “super” El Niño. NBC reports that national weather and climate services have forecasted that a “super” El Niño will develop in the Pacific Ocean over the next few months, intensifying in the winter months. Meteorologists predict that the “super” El Niño will increase the already unusually high temperatures across the entire world. Super El Niños are larger in size and effect, with the possibility of creating a shift in climate patterns for years to come. Research indicates that global warming from fossil fuels could contribute to the formation of these stronger El Niños.
While temperatures were significantly impacted across the U.S., Westchester County has been experiencing fluctuations in weather patterns throughout the past few months. Accuweather reports show that in the span of the first two weeks of March, some days had highs in the 30s while others reached 80s. March 31st had a low of 60 degrees Fahrenheit and a high of 80 degrees. However, two days later the high dropped significantly below the previous low, at 51 degrees Fahrenheit. April 2026 had similar patterns, with temperature significantly rising and dropping over just a few days’ span. Fox 5 accounts these rapid weather swings to cold weather fronts, where large masses of warm air often collide with cold air from polar regions. Meteorologists from Fox 5 described these swings as “weather whiplash,” a term for the rapid shifts between warm and cold conditions due to changing patterns in the atmosphere.
The constant change in temperature can create feelings of uncertainty for future climate patterns. While these shifts are affected by widespread environmental and atmospheric factors, there are some things that communities can do to prepare. Dr. DeMarie suggests, “At a local level, you can do what you can to reduce your carbon footprint… Keep in mind that things are a little different now. You may have to water your own plants in the case of a drought, or you risk losing them.”
In a time where climate change is ever present in daily weather patterns, people must check the forecast daily and research to understand these shifts. As extreme weather becomes more frequent, it’s clear that climate change is not just a future problem, but a present one. These rare record-breaking occurrences may become the new normal. Over the past months people have learned that just because it’s 80 degrees one day, doesn’t mean they won’t be reaching for a coat the next.
