Science confirms: It was a cold winter

Victoria Kelly, Cary Institute Environmental Monitoring Program Manager and Senior Ecologist, prepared this report.

MILLBROOK — Since 1988 the weather station at the Cary Institute of Ecosystem Studies in the Town of Washington has been keeping track of our local weather — precipitation, temperature, wind, air quality, etc.

The News asked Cary’s Victoria Kelly what records showed about this winter. Were these months colder and snowier than last year? How do they compare to historic winters? Is this a normal winter?

December’s average temperature was 30.3 degrees Fahreneit, 1.3 degrees below the 1991-2020 average, which is what weather people refer to as “normal.” The January average temperature was 25.2 degrees, 1.1 degrees below normal, and the February average temperature was 28.4 degrees, 0.3 degrees below normal. So, it’s not your imagination, this has been a cold winter. Note that the 30-year average used to determine “normal” changes every 10 years and doesn’t include the warm winters of the last few years in the comparison.

The record high winter temperature was a balmy 78 degrees Fahrenheit on February 21, 2018, and the record low was a very chilly minus 27 degrees Fahrenheit on January 27, 1994.

Less snow than normal

Overall, the winter of 2024-2025 has been colder with less snowfall than normal. It’s not over yet though. Remember the blizzard on March 14, 2017? Or the April Fool’s Day blizzard March 31-April 1, 1997? March has been known to go out like a lion before, it could very well do it again. Total snowfall this winter so far is 22 inches. Our last accumulating snow was February 15-16. As with many of our events this winter, it began as snow and changed to ice and then rain. We call that mixed precipitation. If we get no more accumulating snow this winter, it will be the fourth winter in a row with less than average snowfall. Our record low snowfall was 13 inches in the winter of 2015-2016. Our record high snowfall was 92 inches in the winter of 1994-1995.

Reports from the suppliers or heating oil and propane estimate that demand increased 15% to 30% so far this winter confirming the findings of the Cary Institute.
