Wind & Wave Calculators
Wind and wave calculators for Beaufort force, wind chill, wave height, wave period, wavelength, apparent wind, and related marine conditions. Use these tools to evaluate common wind and wave relationships used in sailing and maritime operations.
Beaufort Scale Calculator
Enter wind speed in knots, mph, km/h, or m/s to get the corresponding Beaufort force and sea state description.
Use calculator →Wave Height Calculator
Estimate significant wave height from wind speed. Uses simplified empirical relationship for open water.
Use calculator →Wind Chill Calculator
Calculate apparent temperature (wind chill) from air temperature and wind speed. Useful for cold-weather sailing.
Use calculator →Apparent Wind Calculator
Compute apparent wind speed and angle from true wind speed, true wind angle (from the bow), and boat speed. All inputs in knots.
Use calculator →Wavelength from Wave Period
Deep-water wavelength from period using L = gT²/(2π).
