Vermont March Weather: Warm And Weird

A warm March sent daffodil shoots growing much
earlier than normal in Vermont this year. This new
spring greenery had to endure occasional wintry
setbacks, as seen here on March 21. That state
of affairs will continue into April. 

 Well, we got through another month, so it's time to look back at our overall Vermont weather in March, which, as you might have noticed was weird. And warm. 

MARCH TEMPERATURES

Burlington came in with a mean temperature for the month of 38.0 degrees. That puts us in a three way tie with 2010 and 1902 for the sixth warmest March on record. 

It's also the sixth time in a year a month in Burlington was in the top ten warmest list. 

This March was even warmer than the one a year ago, in 2024 which was merely the seventh warmest on record. Yeah, we've had a lot of hot Marches lately. A lot of hot months and years, actually, thanks to climate change. 

The entire rest of Vermont was much warmer than average in March, too. But figures are incomplete, as I noticed missing data on a few days from several of our regular long standing weather stations like Rutland and St. Johnsbury. 

The warmest March day in Burlington was 72 on the 19th and 20th.  This makes March, 2025 one of only 11 Marches in the past 140 years or so to get that warm.  It was not close to the hottest March day on record, though. It was 84 degrees in both March, 1946 and March, 1998.

Rapid snowmelt and some rain led to widespread, but minor flooding across Vermont around St. Patrick's Day. 

You could see the effects of such a mild March by the unusually early signs of spring. Crocuses were blooming by mid-month in a few locations. Green daffodil shoots poked up all through the second half of the month. The sound of returning red wing blackbirds filled the air in marshy areas way earlier in the month than usual. I even had a report of two of people in southern Vermont hearing spring peepers yesterday. That's really early for the season. 

Burlington had its final zero degree reading of the season on March 3. That meant nine days this past winter got to zero or below.  Historically we'd have roughly 20 or more such days per winter, so the downward trend in very cold days continues. 

MARCH PRECIPITATION

It was a little wetter than average virtually everywhere in Vermont in March, which is a good thing since we still have lingering effects from last autumn's drought. 

Precipitation wasn't overwhelming, though, as Burlington had 2.81 inches of rain and melted snow and ice. That's just a little over half an inch above average. By my count, Burlington had its 37th wettest March on record, so not all that impressive.

Precipitation around the state was similarly above average, but not to an extreme extent. 

Winter this March was notably absent until the end of the month. Early in the month, the summit of Mount Mansfield did have its highest snow depth since at least 2019.

But in most of Vermont aside from high elevations, very little snow fell into the end of the month. 

As we just saw, the last weekend of the month brought a big thump of five to nine inches of snow to the north, and a quite damaging ice storm to parts of central and southern Vermont.   

The snow and ice melted quickly during another very warm final day of March, though as of early yesterday, there was still 89 inches of snow near the Mount Mansfield summit. 

APRIL OUTLOOK

April is often regarded as a cruel month, as you think spring is coming, but you always end up getting slapped in the face with winter. 

That's no different this year. 

Today will be much colder than yesterday as many of us won't get out of the 30s. 

And, of course, Wednesday night, we're in for yet another round of snow, sleet and freezing rain. Though it won't be as bad as the last one, eastern Vermont in particular will likely see a glaze of ice, slick roads, and maybe an isolated power outage or two by early Thursday. 

The precipitation should change to rain on Thursday. 

Long range forecasts also call for mostly chillier than normal weather around here through at least the first half of April. We shall see. 

Even if it's a cool April, the forces of spring will win out. Normal temporaries rise rapidly. Today, the normal high temperature in Burlington is 48 degrees and the low is 30. By April 30, the normal high and low temperatures are 63 and 42 degrees.

You're going to see a much greener Vermont landscape by the end of the month compared to what it looks like now.
