Definition
The side of an obstruction, terrain feature, or structure that faces directly into the oncoming wind.
Plain English
The side the wind is hitting first — the side facing the wind.
Context Anchor
Seen in discussions of how wind behaves near terrain and obstacles, especially when judging turbulence and downdrafts near obstructions.
Derivation
‘Windward’ comes from old sailing language: ‘wind’ plus ‘-ward’ meaning ‘toward.’ The windward side is the side the wind is coming toward you from. The opposite side is called ‘leeward.’
Why Pilots Care
Recognizing the windward side allows pilots to anticipate updrafts, downdrafts, and turbulence near ridges or obstacles, supporting safer route and altitude decisions.
Grounding Statement
If you stand outside and feel the wind on your face, the side of your body facing the wind is your windward side. The same idea applies to a hill, hangar, or ridge.
Intuition Check
Do not think of the windward side as a fixed side of an object. It changes whenever the wind direction changes.
Example Sentence 1
Approaching the ridge from the windward side, the pilot expected smooth updrafts as the air was forced up the slope.
Example Sentence 2
When planning a cross-country route, the instructor pointed out that mechanical turbulence would be strongest on the windward side of the hills.
