Easy Wind-Speed Calculation


(Taken from page 88 of the 1996 edition of

"The Old Farmer's Almanac"

-- courtesy Mount Washington Observatory)


To gauge wind speed:


at 10 miles per hour

you can feel the wind on your face;


at 20 small branches move and dust or snow is raised;


at 30 large branches move and wires whistle;


at 40 whole trees bend.


(And, from personal experience.):


At 45 miles/hour,

you’ll be walking

at a 45-degree angle

forward lean!
