Combined signal from wind speed, direction stability, terrain, and thermals. Higher score means better, more predictable conditions for hunting smart with the wind.

Wind Direction
Wind is the most influential environmental factor in hunting. Deer rely on it to survive, bed, travel, and detect danger.
How Deer Use Wind
Bed with wind at their back
Travel with a crosswind
J-hook into bedding areas
Use wind to scent-check food sources from a distance
Wind Speed
Wind speed changes everything. Light winds swirl. Moderate winds stabilize. High winds push deer into cover—but can also spark midday movement when gusts settle.

Movement Patterns by Speed
0–3 mph: Swirling, unpredictable, risky for access
4–12 mph: Ideal, stable, predictable movement
13–20 mph: Deer hug cover, move cautiously
20+ mph: Movement drops until winds calm
Thermals
Thermals rise in the morning as the sun warms the ground and fall in the evening as temperatures drop. In hill country, thermals can override wind direction entirely—pulling scent up or down valleys and slopes.
Thermal Rules
Morning: Thermals rise
Evening: Thermals fall
Midday: Thermals stabilize
Cloudy days: Thermals weaken
Terrain-Based Wind Modeling
Wind interacts with ridges, bowls, and saddles in predictable ways. Understanding how air flows over terrain lets you pick stands where your scent is carried safely away from deer.
On ridges, wind lifts and curls over the top, often creating a leeward side where deer bed just off the crest.
Using Wind to Hunt Smart
Wind determines access, stand choice, bedding approach, and how deer will use the landscape. The best hunters don’t fight the wind—they hunt with it.
