Boston may be chilly today, but it just wrapped up its warmest year recorded yet.

In 2021, the average temperature at Logan Airport was 52.4 degrees Fahrenheit, according to @NWSBoston.

That’s .2 degrees warmer than the previous record set in 2012. bos.gl/sQrg7jd

The news doesn’t come as a big shock, since Boston has been breaking temperature records all year. The city saw above-average temperatures in all but three months of 2021.

It had its warmest winter, third warmest autumn and hottest summer on record. bos.gl/sQrg7jd

The city also failed to set a single low temperature record in 2021. Instead, as the Globe’s Sabrina Shankman previously reported, it experienced nine days where low temperatures were the warmest they’ve been on that day since the start of the historical record in 1872.

Nearby areas were abnormally warm in 2021, too.

Providence saw its warmest year on record, beating out its previous temperature record set in 2020 by just .1 degree. It was also the fifth warmest in Worcester and Hartford. bos.gl/sQrg7jd

“7 out of the 10 hottest years in Boston have been since 2010,” said Stephen Young, a professor of environmental sustainability at Salem State University.

An analysis led by Young, released just last week. found that New England is warming faster than the rest of the planet.

This is in part because the Gulf of Maine, just off the coast of Boston, is among the fastest warming bodies of water on Earth.

"The occasional unseasonably balmy day may be nice," writes @dharnanoor, "but all this warm weather is taking a massive toll on the region."

Just one toll is that heat is particularly dangerous for low-income neighborhoods, which can absorb more heat due to abundant concrete.
