Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of wind. Necessary to lean slightly into the wind to maintain balance. Smoke rises at about 5 to 10 deg. Higher pitched moaning and whistling heard from rigging.

Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind. Whole trees in motion; inconvenience felt when walking against the wind. Moderately high waves of greater length; edges of crests begin to break into spindrift. The foam is blown in well-marked streaks along the direction of the wind.

Nov 11, 2024 · Focus: The Beaufort Scale gauges wind force and its effects on the sea, while the Douglas Scale assesses sea and swell conditions based on wave height. Measurements: The Beaufort Scale connects wind strength with sea conditions, whereas the Douglas Scale independently categorizes sea state and swell height.

The Beaufort Scale is a great way to estimate wind speed by visual observation of the sea surface or land features. The following chart shows the general descriptions for land and sea observations for Beaufort Foce 0 to Force 12.

May 12, 2022 · Wave height: 1-1.5 m - Sea: Small waves becoming longer, numerous whitecaps.

Sea heaps up and white foam from breaking waves begins to be blown in streaks along direction of wind. Twigs break off trees; progress generally impeded. Moderately high waves of greater length; edges of crests begin to break into spin drift; foam is blown in well-marked streaks along the direction of the wind.

A system of estimating and reporting wind speed devised by British Rear-Admiral, Sir Francis Beaufort (1774-1857) in 1805, based on observations of the effects of the wind.

However the Beaufort Scale is still the best way to estimate the wind speed based purely on visual observations of the sea state. In some countries, the scale goes beyond 12, and has classifications from 13-17, which are for special situations like typhoons (hurricanes).

The Beaufort Scale of Wind Force was developed in 1805 by Admiral Sir Francis Beaufort as a means for sailors to gauge wind speeds through visual observations of the sea state. The scale runs from Force 0 (calm) to Force 12 (Hurricane).

The Beaufort scale is used to measure and detail the consequences of different wind speeds on objects on land or at sea. The Beaufort numbers in the Beaufort scale are arranged from 0 to 12 to represent the wind strength from calm (force 0) to the hurricane ( force 12).
