Downwind vs. Upwind: What's the Difference?

Edited by Aimie Carlson || By Janet White || Updated on November 11, 2023
"Downwind" refers to the direction the wind is blowing towards, while "upwind" is the direction from which the wind is coming.

Key Differences

"Downwind" indicates the direction towards which the wind is blowing, often carrying scents or sounds with it. While, "upwind" points to the source of the wind, often a cleaner or fresher direction since it's where the wind originates.
In navigation or aviation, traveling downwind means moving with the wind at one's back, which can aid in speed and efficiency. Traveling upwind, however, means moving against the wind, which can be more challenging and require more energy.
When considering pollution or odor control, being downwind of a source means you're more likely to detect or be affected by it. Being upwind means being in a position less affected by such emissions.
In sailing, downwind courses are often faster and require different sail settings than upwind courses, which need more tacking and strategic maneuvering.
Downwind areas can be more susceptible to receiving fallout or debris from activities like construction, whereas upwind areas are typically clearer of such influence.

Downwind and Upwind Definitions


In the direction that the wind is blowing towards.
The farm is located downwind of the factory, often receiving its smoke.


The windward direction in nautical terms.
Sailing upwind required careful tacking and navigation.


Being in a position where the wind blows something towards you.
Downwind of the bakery, the smell of fresh bread was overwhelming.


Towards the source or origin of the wind.
Birds often migrate upwind to utilize the air currents effectively.


On the side away from the wind.
They set up camp downwind to avoid smoke from the campfire.


On the side facing the wind.
The wind turbines were positioned upwind to capture the strongest winds.


The leeward direction in nautical terms.
The boat sailed downwind, making the journey smoother.


In the direction from which the wind is coming.
The hikers walked upwind to avoid the smoke from the forest fire.


The direction in which a scent or pollution is carried by the wind.
They noticed the odor from the landfill while standing downwind.


Being in a position where the wind is blowing away from you.
Upwind of the chemical plant, they didn't notice any unpleasant smells.


In the direction in which the wind blows.


In or toward the direction from which the wind blows.


In the same direction as the wind is blowing


Exposed to the wind


Positioned relative to something in such a way that it can be smelled in the wind
I don't want to live downwind from a pig farm.


In the direction from which the wind is blowing


(aviation) in the direction opposite that of landing in a traffic pattern


To wind upwards.


On the side or in the direction away from the direction from which the wind is blowing; in the direction toward which the wind is blowing; as, good hunters stay downwind of their prey. Opposite of upwind, and windward.


To wind up (a mechanism).


Towards the side away from the wind


To wind up.


In the direction the wind is blowing;
They flew downwind


Being or moving in the direction from which the wind is blowing.


Away from the wind;
They were sailing windward


Towards the side exposed to wind


Toward the wind;
They were sailing leeward


In the direction opposite to the direction the wind is blowing;
They flew upwind


What is the meaning of downwind?

Downwind means in the direction towards which the wind is blowing.

Why is being downwind important in sailing?

Being downwind in sailing helps with faster movement as the wind aids in propulsion.

Is it easier to smell things downwind?

Yes, scents are often more detectable downwind as the wind carries odors in that direction.

How is upwind defined?

Upwind is the direction from which the wind originates.

How does upwind benefit wind turbines?

Positioning wind turbines upwind ensures they capture the strongest and most consistent winds.

Can weather patterns be predicted by downwind conditions?

Downwind conditions can give clues about weather patterns, especially in terms of where weather systems are moving.

What challenges does upwind present in aviation?

Flying upwind in aviation can be challenging due to increased air resistance.

Can downwind affect the spread of fire?

Yes, fires can spread rapidly downwind due to the wind carrying the flames and heat.

What is the strategic advantage of being upwind in battle?

Being upwind in battle can provide a strategic advantage by keeping smoke and gasses away.

How does being upwind affect scent tracking in animals?

Animals often position themselves upwind to prevent their scent from reaching prey.

Is upwind sailing more difficult than downwind?

Yes, upwind sailing can be more difficult due to the need for strategic tacking against the wind.

How does smoke disperse in a downwind direction?

Smoke disperses downwind as it is carried along by the wind's flow.

Why is it important to consider downwind conditions in agriculture?

Considering downwind conditions in agriculture is important to avoid pesticide drift to neighboring areas.

How does pollution travel downwind?

Pollution travels downwind as the wind carries contaminants in that direction.

Why do pilots prefer landing downwind?

Pilots usually prefer not to land downwind; landing upwind is often safer due to better control against the wind.

How do plants adapt to upwind and downwind conditions?

Plants adapt to these conditions by altering growth patterns and seed dispersal strategies.

What impact does downwind have on air quality?

Air quality can be poorer downwind of pollution sources due to the accumulation of pollutants.

What is the significance of downwind in environmental studies?

In environmental studies, downwind analysis is crucial for assessing the impact of pollutants and emissions.

Can downhill and downwind mean the same thing?

No, downhill refers to terrain slope, while downwind refers to wind direction.

How do birds use upwind conditions during migration?

Birds use upwind conditions to gain lift and conserve energy during migration.
