The first scale to estimate wind force with general description in english, italian, french and spanish

NOTE
The waves probable height shows the expectable conditions of the open sea, very far from the coasts. It should never be used in opposite sense to estimate or signal the sea state. Please remember that in internal seas and near the coasts with land winds, the waves will be lower

HISTORY
The scale takes its name from admiral Francis Beaufort (1774-1857), hydrographer of the Royal Navy, who in 1805 proposed a method to classify the wind force into 13 degrees. In 1831 the scale was first used on the Beagle in the celebrated voyage and in 1838 it was officially adopted by British Admiralty and later by all other countries
