BEAUFORT SCALE

The Beaufort Scale is a system for estimating wind force 

without the use of instruments based on the visible 

effects of the wind on the physical environment. The 

behavior of smoke, waves, trees, etc., is rated on a 13 

point scale. The scale was devised in 1805 by the British 

naval Commander Sir Francis Beaufort (1774-1857) and 

is still commonly used by mariners.
