• What is steam fog?


    SCITUATE, Mass. - This extreme cold stretch has resulted in a lot of chaos; from bone-chilling wind, to snow and ice.

    Tuesday morning, a Boston 25 News viewer sent in a photo of something we haven’t seen much of. A photo looking at the lighthouse in Scituate with smoke coming from the water. 

    We turned to Boston 25 StormTracker Meteorologist Jason Brewer to find out about this “sea smoke.” 


    Sea smoke is typically used to describe this meteorological happening in polar regions. Here, it should be referred to as steam fog, which, according to the American Meteorological Society, is very similar. 

    So, what is it?

    The fog is formed when water vapor condenses and is added to air that is much colder than the vapor’s source. Simply put, when very cold air drifts across relatively warm water. 

    Science aside, it makes for a cool picture!
