This is the definition of a calm wind, according to the Beaufort scale. A calm wind is a light breeze that is barely noticeable. It is often described as a &#8220;gentle breeze&#8221; or a &#8220;light air.&#8221;<\/p>\n<p>The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> or on land.

A calm wind can make it difficult to sail or row, and it can also make it difficult to hear or see other people.
