Northwest (direction)

Characteristics

As an ordinal or intercardinal direction, northwest sits between the primary cardinal points. It appears on the compass and on the traditional compass rose used by mariners and cartographers. The direction can be subdivided into more precise headings such as north‑northwest (NNW) and west‑northwest (WNW) when greater accuracy is required.

History and development

The concept of northwest arose with early seafaring and land navigation when people formalized the four cardinal points and then the intermediate points between them. Compasses, stars and later magnetic and gyro instruments made it possible to assign standard bearings to these directions for consistent use in maps, charts and early exploration.

Uses and examples

• Navigation and piloting: used to plot courses and report headings.
• Weather reports: winds from the northwest are commonly described in forecasts.
• Geography and regional names: areas such as the Pacific Northwest are identified by their general location.
• Everyday wayfinding: giving directions by compass points or landmarks.

Notable distinctions

Northwest should not be confused with adjacent points like NNW or WNW, which indicate bearings closer to north or west respectively. In many systems the term is exact and paired with its opposite, while in colloquial speech it may also simply mean ‘‘toward the upper left’’ on a standard map. For further context and standards, see navigational references and glossaries (compass materials) and regional descriptions (north and west relationships).

For concise comparisons and additional maps or diagrams that show how northwest relates to other points, consult basic navigation guides and introductory cartography resources (compass rose, southeast).
