On a typical blustery British day, when the wind is buffeting the trees and turning your umbrella inside out, if you were to guestimate the strength of the wind it’s very common to overestimate.
Wind is the motion of air and is omnipresent. Its causes are numerous, ranging from vast global trade winds due to hemispheric temperature differences to gentle sea breezes as the land warms up.
What speed may require you to lean into the wind to steady yourself, or perhaps even force you back a step as a gust hits? I’ve asked people to guestimate this and answers have included 70mph, 80mph and even 100mph. In fact, a gust of only 40mph would be enough to unsteady you.
