Beaufort Wind Force Scale
The Beaufort Wind Force Scale, commonly referred to as the Beaufort Scale, is a measure that relates wind speed to its effects observed on both sea and land. It was first devised in 1805 by Admiral Francis Beaufort, an Irish-born officer in the Royal Navy. The scale has been modernized and standardized since then, and it assigns a number 0-12, called the Beaufort number, and a description to wind speeds falling into certain speed brackets.
The following is a list of the Beaufort numbers, along with the descriptions, and the wind speeds associated with each.
0 Calm <1 mph
1 Light air 1-3 mph
2 Light breeze 4-7 mph
3 Gentle breeze 8-12 mph
4 Moderate breeze 13-18 mph
5 Fresh breeze 19-24 mph
6 Strong breeze 25-31 mph
7 High wind/near gale 32-38 mph
8 Gale 39-46 mph
9 Strong gale 47-54 mph
10 Storm 55-63 mph
