MARITIME – METEOROLOGY & EA TATE CALCULATOR
Beaufort To Sea State
A precise tool.
What is the Beaufort To Sea State & How does it work?
The Beaufort scale, devised in the early 19th century, quantifies wind speed based on observed sea conditions, ranging from 0 (calm) to 12 (hurricane).
Mariners translate Beaufort numbers into sea states, which describe wave height and surface roughness, enabling safe navigation and operational planning.
A simple empirical relationship links the Beaufort force (B) to an estimated wave height (H) in metres, providing a quick conversion for on‑deck calculations.
H = 0.1 \times B^{2}
H = wave height (m) B = Beaufort force

Frequently Asked Questions
How do I convert a Beaufort number to wave height?
Multiply the Beaufort number by itself and then multiply by 0.1 to get the wave height in meters.
What is the maximum wave height according to the Beaufort scale?
The maximum wave height occurs at Beaufort force 12, which would be 0.1 * 12^2 = 14.4 meters.
Can you explain what each Beaufort number represents in terms of sea state?
Beaufort numbers range from 0 (calm) to 12 (hurricane), with increasing wind speeds and more turbulent seas as the number goes up.
How is this calculator useful for mariners?
It helps mariners quickly estimate wave heights based on wind conditions, aiding in safe navigation and operational planning.
What is the empirical relationship used in this calculator?
The relationship is H = 0.1 * B^2, where H is the wave height in meters and B is the Beaufort number.
Is there a specific use case for this calculator during storms?
Yes, it's particularly useful during storms when mariners need to assess potential wave heights based on wind speeds.
