Wind Direction

Wind direction, measured as the azimuth from which wind blows in degrees clockwise from north, is a fundamental parameter that determines cloud movement patterns, moisture transport, wave conditions, and precipitation drift, making it essential for predicting photography opportunities. Unlike wind speed which indicates intensity, wind direction reveals the source and trajectory of air masses, allowing photographers to anticipate atmospheric changes hours before they arrive.

Offshore winds (blowing from land toward water) push moisture away from coasts, clear marine layer fog, and create smooth water surfaces ideal for seascape photography, while onshore winds (from water toward land) bring moisture inland, form coastal fog, and produce waves and swells perfect for dramatic ocean scenes. Wind direction relative to terrain determines orographic effects: winds blowing upslope force air to rise and cool, forming clouds and precipitation on windward sides while leaving leeward sides clear, creating the rain shadow effect that lets photographers choose cloud-draped windward locations or clear leeward alternatives from the same storm system.

For coastal fog photography, winds from warm water toward cool land (often overnight onshore flow) produce dense advection fog, while daytime sea breezes from cool water toward warm land may bring fog inland during afternoons. Wind direction also determines wave approach angles for seascape composition, drift direction for rain and snow in foreground elements, and the side of clouds where shearing and interesting textures develop. PhotoWeather tracks wind direction shifts to forecast frontal passages where wind veering from southwest to northwest indicates cold front clearing, predict fog formation when winds shift to favorable moisture advection patterns, and alert photographers to sunset enhancement from westerly winds transporting dust and particles that scatter light. Understanding prevailing wind directions for specific locations helps photographers recognize when unusual wind patterns create unique opportunities: easterly winds in typically westerly climates often bring extreme clarity or unusual weather, while wind reversals can trigger fog formation or dissipation within hours. Mariners know wind direction dictates wave conditions; photographers learn that wind direction similarly controls atmospheric drama, determining whether moisture arrives or departs, clouds build or clear, and whether to seek windward drama or leeward clarity.
