Mount Washington in N.H. is colder than Mars

It’s apparently never too cold for a science experiment at the Mount Washington Observatory in New Hampshire.

With a temperature of 31 degrees below zero, weather observer Adam Gill trekked outside early Thursday morning in a heavy yellow coat and ski mask, and struggled to stay standing in “hurricane force winds.”

In a video posted on Facebook, he shows what happens when you pour out a pot of boiling water in those conditions — the scalding-hot liquid immediately turns into a stream of snow, carried away by the wind.

Weather atop the 6,288-foot summit is often painfully cold and windy. The temperature hit a record low of minus 34 degrees Thursday morning, with winds as high as 110 miles per hour. Wind chills reached as low as minus 89 degrees.


If you described those conditions as “out of this world,” you would, in a sense, be correct — the temperature on Mount Washington was colder than the temperature recently recorded on Mars, as reported by The Atlantic.

Weather data from the Curiosity rover on the red planet’s surface recorded a temperature of minus nine degrees on Dec. 20. The rover is near the planet’s equator, where the cold season has just begun, The Atlantic reported.

The conditions have somewhat improved atop Mount Washington since Thursday. As of Saturday night, it was minus 13 degrees, with a wind chill of minus 46 degrees and gusts of 36 miles per hour.
