The Beaufort scale is a scale for measuring wind speeds. It is based on observation rather than accurate measurement. It is the most widely used system to measure wind speed today. The scale was developed in 1805 by Sir Francis Beaufort.There are twelve levels, plus 0 for no wind. From 1946 to 1970, there were also beaufort levels 13 to 17.he Beaufort scale is a scale for measuring wind speeds. It is based on observation rather than accurate measurement.

However long before anemometers there was the Beaufort wind scale used by sailors on the high seas with 13 Beaufort numbers ranging from 0 to 12 (based on the Deep-sea criterion of 1874) which says 0 is calm and 12 is That which no canvas could withstand, 0 is wind speed of 1 knot and 12 is wind speed of greater than 65 knots.
