World Had Fifth Warmest January Despite Arctic Block That Kept Parts Of Europe, U.S.

January was the worlds fifth warmest on record 
Blocking high pressure in the Arctic kept that
region exceptionally warm, while parts of 
Europe and North America were 
a little cool as a result of that blocking

It might have seemed cold locally, but the world had its fifth warmest January on record, according to NOAA's National Centers for Environmental Information. 

"This marks the 50th consecutive January (since 1977) with temperatures, at least nominally, above the 20th -century average. The 10 warmest Januarys on record have occurred since 2007, with the most recent five years (2022-26),"  NCEI noted in its monthly report.    

When you look at the data and maps from this monthly report, you can really see in this report how a persistent blocking pattern messed with temperatures in the northern hemisphere. 

High pressure over the Arctic and Greenland made that area super warm compared to average. That was especially true in northern and western Greenland and northeastern Canada.

Meanwhile, this pattern squashed the frigid air in the Arctic southward. That's why the eastern United States, northern and central Europe and most of the western two thirds of Russia were on the cool side.  

The cold air was also forced to spread out over a larger land area by this pattern, helping keep the world's January as a whole cooler than it otherwise would have been overall. Also, the effects of La Nina, which tends to cool the world, would be peaking roughly about now. 

No areas came close to the coldest on record. 

Fifth hottest is still impressively warm. Given the factors above, January shouldn't have been that warm. Climate change is still ruling the roost. As we previously reported, an El Nino is brewing for later this year, and that could bring the world's temperature to new and dangerous heights late this year or in 20247. 

In January, 2026, besides the Arctic, other areas that were much warmer than normal were Africa, which had its warmest January on record. Other hot areas include central Asia, southern Australia, much of western Canada, the western United States and the Atlantic Ocean between the Caribbean and Africa. 

UNITED STATES

The data confirms it: We had a remarkable west-east divide during January. 

Data confirms the Lower 48 had a warm west and a 
cold east Note that western temperatures were
near record highs, while eastern temperatures
were generally just somewhat cooler than average.

The East had a real winter, while the West was having a year without a winter in January. As NCEI tells us: 

"Temperatures were much above average across a large portion of the western third of the (United States). Oregon, California, Utah and Arizona each had one of the six warmest starts of the year. Along with Washington, Nevada and New Mexico, they each recorded their warmest December-January period on record."

Thought the East was cold, the chill didn't come close to breaking records for the month. Ohio came the closest, ending the month as 31st coldest out of the past 132 years. Pennsylvania was 32nd coldest .

For the record, we in Vermont had our 75th coldest January, or 57th warmest January, depending on how you want to look at it. 

Mix it all together and the United States ended up having its 19th warmest January. 

Precipitation was scant, despite a wide-ranging winter storm toward the end of the month. January ended up as the eleventh driest on record for the Lower 48. The Northwest and northern Rockies were particularly dry. Oregon and Montana had their fifth driest Januaries on record. 

Only four states - Kansas, Michigan, New Mexico and Wisconsin were noticeably wetter than average and even those states did not come anywhere close to record wet.

Here in Vermont, we had our 48th driest January out of the past 132 years.  

January had a few other impressive weather events that I missed as they unfold.

On January 8 and 9 rare winter flash flooding occurred in parts of Wisconsin and Illinois amid a burst of record warmth that brought temperatures in the low 60s, and heavy rain. Up to three inches of rain fell near Chicago.  Chicago had as much rain in one day as they normally have in the entire month of January. 

Alaska had rough January. We already reported on the epic, record snows around Juneau in December and early January, which were followed by flooding. But two of Alaska's other larger cities had their own issues. 

The temperature in Fairbanks never got above zero for 32 consecutive days ending on January 14. That's the longest stretch of continuous subzero cold in more than 100 years.  Down in Anchorage, January snowfall set a record with 40.2 inches of snow.

On the warm side of things, St. Thomas in the U.S. Virgin Islands had their warmest January on record with an average temperature of 81.6 degrees.
