March Was World 2nd Warmest, Possibly Signaling New Hot Push, U.S., As Expected Shattered March Heat Records

March, 2026 was tied for the second warmest on
record on Earth. With an El Nino coming,
the month's temperatures could be a signal
that unprecedented hot times could
be on their way.

 The global temperatures in March were back to their old tricks, going back to second hottest on record after several months of "cooler" months that were only in third place in the hottest months list.

Even hotter, more dangerous times might be ahead in the coming months or year or two. 

Actually this March barely squeaked into second place. It was virtually tied with March, 2024. The National Centers for Environmental Information continues: 

"All March global temperature departures ranking in the top 10 during the period 1850-2026 have occurred since 2015. This month marked the 50th consecutive March with a global temperature departure above the 20th century average."

The March, 2026 global temperatures might represent an ominous reversal in ever-so-slightly cooler trends we saw over the past year or so.  La Nina, which tends to cool the global climate, put a stop to a month after month stretch of almost continuous record global heat in 2023 and 2024.

Starting last June, most months were the third warmest on record. That's scary enough, since La Nina could barely put the most unnoticeable dent in the effects of climate change. The effects of La Nina might have peaked this past winter. December, January and February were all the world's fifth warmest, respectively. 

La Nina has faded and it loos like El Nino - which generally warms the global atmosphere - might be developing. It could be a strong one, and that could send the world's temperatures skyrocketing to new, dangerous heights by next year. 

The higher the global temperatures, the higher the risk of killer heat waves, worst droughts, increasingly torrential floods and more intense, less predictable storms. 

THE DETAILS

As always in this age of climate change, cold spots were hard to find in March.  However, there was a notable very cold area in Alaska and the Yukon Territory of Canada. That area was much colder relative to average than we usually see in these monthly reports. 

The only other slightly chilly areas I could find on the NCEI maps were small areas in northwest Africa, Antarctica, the extreme southeastern Pacific ocean and northwestern Siberia.  And what is now almost a perennial area of coolness hovered over an area of the North Atlantic a little south of Greenland. 

Also, although March as a whole in Australia wasn't cold, a sharp frigid snap at the end of the month shattered decades-old March temperature records in many cities, NCEI reports. Two Australian cities reported all-time record lows. 

The most wild hot spot relative to average was the contiguous United States. I'll have more on that below. Other really notable hot spots relative to average were in the entire Arctic (north of that Alaskan cold spot), northern and eastern Europe, large areas of Asia and spots across Africa and Antarctica.

Year to date, the first three months of 2026 is so far the fourth warmest year on record. It's almost certain this year will be among the top 10 warmest on record and likely among the top five. 

As is usually the case for March, Arctic sea ice extent reached its maximum extent of the year on the 15th. It wasn't that extensive. The ice covered 5.52 million square miles, statistically tied with last year for the smallest maximum in the 48 years satellite have been keeping track, according to the National Snow and Ice Data Center. 

UNITED STATES

The contiguous United States was exceptionally 
warm in March, breaking records from 
coast to coast. We'll see if it's a harbinger
 of a torrid summer. 

As we have been reporting, March, 2026 was ridiculously, insanely hot in the Lower 48. Now we have the final receipts.  

NCEI tells us: 

"The average temperature over the contiguous US (CONUS), in March was 50.85 degree F, 9.35 degrees F above average, ranking as the warmest March in the 132-year record. This marks the first time any month's average temperature has exceeded 9 degrees F above its 20th-century baseline. It also includes the warmest 12-month period on record for the CONUS (April, 2025-March 2026)"

Even more remarkably, the nations average high temperature during March was 64.4 degrees, an incredible 11.4 degrees above the 20th century average. That super warm March average daily maximum was actually 0.9 degrees warmer than the average April high. 

 Ten states had their warmest March on record. They were all large states in the southwestern United States, so those made up about a quarter on the United States. Included those ten, 35 states had one of their top 10 warmest Marches on record. 

Put another way, more than 500 counties, covering more than one quarter of the Lower 48 and affecting about 79 million people, recorded their warmest March on record, NCEI tell us. 

The "coldest" state was Maine, but even they were well above normal.  Maine had their 33rd warmest March out of the past 132 years. Vermont was one of a handful of other very warm but not super warm states. The Green Mountain State had its 19th warmest March. 

Mostly because of the continuing record high temperatures in the Southwest and Rockies all year so far, January-March is also the hottest on record. 

There was one particular cold spot in the United States: Alaska. The state had its fourth coldest March out the past 102 years. The last time Alaska had a March that cold was in 1972.

The heat, relative to average, diminished a little in the United States in April, so I'm guessing we'll get a break in the month after month reports of record warmth. 

The United States also had its eight driest March on record. In general, the states that were the warmest in March were also the driest. California had its driest March on record. Eight other states in the Southwest and Southeast had one of their top ten driest Marches.

The only really wet areas was around the eastern Great Lakes. Michigan had its third wettest March. Here in Vermont, March precipitation was right around average.  

It'll be an interesting to see whether March was a prelude to an extraordinarily hot summer, or just another month that really went off the rails. 

Climate Change Footprint Is Everywhere, As I'm Learning In Scotland

A stormy late afternoon Monday in Edinburgh, Scotland.
Just like in many parts of the world, including back home
in Vermont, storms are getting more extreme in
Scotland due to climate change. 

EDINBURGH, SCOTLAND - As any good tourist would do, I'm trying to learn as much as I can about the city.  

Given my interest in weather and climate, that includes information on how climate change is affecting Scotland. 

Turns out climate change is affecting this area in similar ways to Vermont. Just as in the Green Mountain State, climate change is making Edinburgh warmer and wetter.  

Edinburgh is not a warm place.  It's almost as far north as Anchorage, Alaska. It's as far north as north-central Quebec.  

But it's not frigid here. The waters of the Gulf Stream in the Atlantic Ocean keep things moderate and tolerable in Scotland, though. 

Daytime highs in the winter tend to be in the low 40s around Edinburgh and summertime highs are in the mid-60s . Extremes in Scotland are not as wild as they are in most of the United States, including Vermont. 

The coldest temperature on record here is 4 degrees (Fahrenheit). The hottest-ever reading hit pretty recently, 88 degrees on July 25, 2019. That being one sign of climate change right there.

By contrast, Burlington, Vermont has been as cold as 30 below and as hot as 101 degrees, so the range is much greater than in Scotland. 

Any sort of change in the climate anywhere is disconcerting and potentially destructive. That's of course true in Scotland. 

With climate change, summers in Scotland are expected to become drier overall, but with more intense storms thrown in.  That means a higher chance of drought, and also a higher chance of flash floods. That   scenario might sound familiar to us Vermonters, who in recent years dealt with summer droughts, and disastrous July and August flooding. 

Autumns are getting especially risky in Scotland, with flooding increasing at that time of year. Just this October, Storm Babet caused some of the worst flooding on record in much of Scotland. All seasons in Scotland are expected to be warmer than they are now. 

Climate change is on the minds of politicians and policy makers here in Scotland. 

The City of Edinburgh Council has a pretty detailed plan on their web site on dealing with the consequences of climate change.  They're most worried about flooding from storms and from sea level rise. 

Edinburgh is of course a coastal city, meaning it's prone to the effects of sea level rise. The estimates are sea levels at the Edinburgh harbor should rise by about six inches by 2050, That doesn't sound like much, but even a slight sea level change can add immensely to storm surge damage and waves.

Scotland as a whole has a goal of net zero carbon emissions by 2045. I have noticed a large number of EVs in Edinburgh. They make sense here. There's usually need to go any long distances. The streets are narrow and winding, so you don't want a large car here.  Since it's a compact city, it's easy to walk or bike to wherever you're going.

Also, Scotland has a robust public transit system, which is great if you want to reduce carbon emissions. Edinburgh is crawling with buses, and I always see plenty of passengers on them. The train network is extensive and very easy to use. 

We took a day trip from Edinburgh to New Berwick on the coast about 20 miles to the northeast Sunday. The train to and from there was efficient, clean and convenient.  Wish we had something like that in the states! 

Both Vermont and Scotland, along with local and regional governments around the world do seem to be  taking action against climate change, and girding themselves against the effects from it.  It seems like the top leaders of the world, and especially the wealthy billionaire class who made their money on fossil fuels and associated industries that are holding us back from solving the climate crisis. 

 

  

It Wasn't Just U.S. That Had Incredible Late Dec/New Years Warmth

Map from Pivotal Weather depicts record heat in much of
Europe over the New Years holiday. 

 The world had a dizzying array of record warmth during Christmas week and the first couple of days of January.  

Though there were certainly cold sections of the world, too (I see you, Northern Plains, Pacific Northwest and southwestern Canada!)  much of the world was hot, hot hot as 2021 closed and 2022 began.

A lot of the data I have here in this post comes from Extreme Temperatures Around the World (@extremetemps) on Twitter, which is a great resource to track all these weird records that keep happening. 

Several spots in the United Kingdom had their hottest New Year's Day on record. Scotland had its hottest New Year's Day at 15.9 C or 60.6 degrees F.  Wales also had its warmest first day of the year with 15.6 C or 60 degrees F. 

Paraguay had its all time record high for any date on January 1 as one town soared to 45.6 degrees C, which is a scorching 114 degrees Fahrenheit. The old record was set just last year. 

Also in South America, the closing days of December brought Buenos Aires, Argentina a record high for the month of 40.1 C or 104 F.  It was also the hottest it's been in the Argentinian city since 1999.

On New Year's Eve, some German towns and cities set records for hottest December temperatures as high as 16.9 degrees C or 62.4 F.  Note that due to the normal seasonal downward trend in temperatures, you'd expect the hottest December records to come early in the month. 

Elsewhere in Europe, Bilbao, Spain recorded its warmest December day on the 30th with 24.7 C or 76.5 F.

Back here in the United States, there was a report of a temperature reaching 99 degrees in Falcon Lake, in far southern Texas on New Years Day. If this report verifies, it will be the hottest temperature recorded anywhere in the United States during January. 

As previously reported, Alaska also had its hottest temperature on record for December, and it was the hottest day of any between November through mid-April.  I initially said that reading was 65 degrees, but there was also a report of 67 degrees in or near the same town. 

This is one statistics heavy post, I get it.  But it's an illustration of how heat records are falling so rapidly around the world as the climate warms.

These patches in which a lot of record fall around the world seem to come in waves. This particular wave seems to be over, as fewer big records, if any are falling around the world as we make it throuh this week. 

However, I'm sure there will be plenty more heat records as we make it through 2022.
