Wind direction is generally reported by the direction from which the wind originates. For example, a north or northerly wind blows from the north to the south; [1] the exceptions are onshore winds (blowing onto the shore from the water) and offshore winds (blowing off the shore to the water). Wind direction is usually reported in cardinal (or ...
The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.

In the Hebrew Bible, there is frequent reference to four cardinal directions. [5] The names of the directions seem to be associated with physical landmarks for the ancient Israelites living in the region of Judea, e.g. East is referred to as kedem, which may derive from "edom" ("red"), and may be a reference to the color of the rising dawn, or the red sandstone cliffs of the Land of Edom to ...
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
A compass rose or compass star, sometimes called a wind rose or rose of the winds, is a polar diagram displaying the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is used on compasses (including magnetic ones), maps (such as compass rose networks), or monuments.
A Santa Ana fog is a derivative phenomenon in which a ground fog settles in coastal Southern California at the end of a Santa Ana wind episode. When Santa Ana conditions prevail, with winds in the lower 2 to 3 kilometers (1.2 to 1.9 mi) of the atmosphere from the north through east, the air over the coastal basin is extremely dry, and this dry ...
Yardarm: an end of a yard spar below a sail. Waterline: where the water surface meets the ship's hull. Weather: side or direction from which wind blows (same as "windward"). [17] Windward: side or direction from which wind blows (opposite of "leeward"). [17]
In geography and seamanship, windward (/ ˈ w ɪ n d w ər d, ˈ w ɪ n ər d /) and leeward (/ ˈ l iː w ər d, ˈ lj uː ər d /) are directions relative to the wind. Windward is upwind from the point of reference, i.e., towards the direction from which the wind is coming; leeward is downwind from the point of reference, i.e., along the ...
