Persistent overcast skies are a frequent characteristic of London’s weather patterns. This phenomenon is primarily attributable to the city’s geographical location and prevailing weather systems.
The confluence of maritime air masses from the Atlantic Ocean and the city’s position in a region of frequent cyclonic activity contribute significantly to this atmospheric condition. This interaction often results in the formation of extensive cloud cover throughout the year. Moreover, historical industrial activity has left a legacy of atmospheric particulates, which can act as condensation nuclei, further promoting cloud formation.
