Sit a stand only on a wind that carries your scent away from where deer will come from and where they bed, and away from your walk in. Work out those winds for each stand before the season, check the hourly forecast the night before, and leave the stand alone on any other wind. In hill country, the air also rises on sunny mornings and sinks toward evening, and in a light wind that can move your scent more than the forecast does.
Why the wind decides the sit
A whitetail’s nose has about 297 million scent receptors, according to the National Deer Association. A dog has about 220 million, and you have about 5 million. Missouri’s Department of Conservation puts it simply: set the stand so the prevailing wind blows your scent away from any deer that may pass under it, ideally toward a place deer rarely go, such as a big pond, a road or a steep drop.
Getting it wrong costs more than one sit. In a South Carolina study of GPS-collared deer, both bucks and does generally avoided the parts of the property that were hunted most often, during daylight (Stewart and others, Ecology and Evolution, 2022).
Work out the winds each stand hunts
Do this once for every stand, on a map or standing at the tree:
- Mark where deer come from. The bedding, the trail or funnel the stand covers, and the food they’re headed to.
- Mark where your scent can go. Open water, a road, a steep drop, or woods deer don’t use.
- List the winds that carry scent from the stand to that safe ground. If a west wind blows your scent out over the creek and away from the bedding, west is one of the stand’s winds.
- Check the walk in on the same wind. The National Deer Association’s advice is to hunt a stand only when the wind suits both the stand and the route to it. If your route blows scent into bedding cover, change the route or pick another stand.
- Write it down. “Creek stand: W, NW, N.” Then the night before a hunt, you only need the hourly forecast to know where to sit.
If no stand fits the wind, stay out. “Don’t be a rebel; hunt the right wind,” as Alex Foster puts it for the National Deer Association.
What changes the wind at a stand
The forecast gives the wind across open country. Ground and trees bend it.
| Spot | What the wind does | Source |
|---|---|---|
| Ridgetop | Usually the most consistent wind | Missouri Dept. of Conservation |
| Valley or drainage | The wind swirls and mixes with thermals | Missouri Dept. of Conservation |
| Light, shifting breeze near rocks or hillsides | Splits and eddies, and can drift back upwind, most often under about 8–10 mph | National Deer Association |
| North-facing slope, morning | Warms later, so air keeps sinking longer after sunrise | National Deer Association |
| South-facing slope, day | Upslope air can run several times faster than on the north slope across from it | Forest Encyclopedia Network |
| Ground blind | Your scent stays closer to the ground, so the wind matters even more | Missouri Dept. of Conservation |
Thermals: sit high in the morning, low in the evening
Thermals are air moving up or down a slope as the ground heats and cools. They’re strongest on sunny days, and they swirl when they meet the prevailing wind, Missouri’s Department of Conservation says.
- Morning. Air starts flowing up a slope within minutes after the sun hits it. Your scent goes uphill with it, so a stand above the deer works. Before the sun reaches the slope, the air may still be sinking. A north-facing slope stays cool longer and keeps air sinking into the morning.
- Late afternoon. The change starts when the first slopes fall into shadow: the upslope air dies, there’s a calm, then a slow, shallow flow downhill (Forest Encyclopedia Network).
- Evening. Cooling air carries your scent downhill and settles it in the lowest ground nearby, the way fog and frost do. In hill country, that’s often the bedding. The National Deer Association’s Anthony Harris has seen this happen with a breeze of under 10 mph. His rule is to hunt high in the morning and low in the evening, and he does about 85% of his hunting from morning through midday because of the falling evening air.
A strong wind can wipe this out. Cold, dense air behind a cold front with a strong general wind follows the ground and can erase the valley winds, according to the Forest Encyclopedia Network. At night, though, cold air pooled in the valleys usually shields the low ground from the wind above it.
Wind speed: deer still move
Most hunters expect deer to lie down when it blows. In a Penn State Deer-Forest Study survey, almost 90% of more than 1,600 readers said deer move less on windy days. Collared deer in Pennsylvania in October 2013 did the opposite: bucks and does moved about a tenth of a mile more in daylight on windier days, and about a tenth of a mile less on windy nights. The wind that month never got above 12 mph, so the study says nothing about strong wind.
Sources disagree here: the National Deer Association writer who measured eddying scent says deer tend to move less in a stronger wind, while the Penn State data showed more daytime movement at up to 12 mph. What both agree on is that a steady wind pushes your scent one way, and a light, shifting one doesn’t.
Check it at the tree
- Watch the air before the season. The National Deer Association suggests a smoke bomb at each stand: it burns about 2 minutes and the smoke may show you 50 yards downwind. Do it at the hours you’ll hunt, since thermals change through the day.
- Move the stand a few yards if you need to. The same writer found that a few yards changed where his scent went, and that it took three or four sits to learn the right wind and time for a new spot.
- Keep your walk in clean. Don’t cross food plots where deer will come later. Walk a creek if you can. Wear thin layers in and put the warm ones on at the tree so you don’t sweat.
How DECOHunt does it
In DECOHunt, you give each stand the winds it hunts, and DecoCast ranks your stands for each sit from the hourly wind. A stand’s card opens with its best sit this week, then the hours its wind fits. Tap an hour and the scent cone swings to that hour’s wind, pointing downwind, wider and shorter in light air. Stands show the walk from parking. Each sit you start saves the hour’s wind and weather, and the AI reads the log for deer seen and bucks per stand, by wind. See how stands and wind work in DECOHunt.
