Cold, the trigger
In Quebec, a sudden temperature drop is one of the best pieces of news for a hunter. When the mercury plunges, especially after a mild spell, big game becomes noticeably more active in daylight. Comfort improves for deer and moose: they move and feed without overheating.
First frost
The first real autumn frost marks a turning point. It signals to game that winter is coming and stimulates weight gain. Feeding areas (apple trees, crops, fresh growth) become heavily used early morning and late day. It's an excellent time for stand hunting near food sources.
Cold and the rut
Cold also acts as a rut catalyst. A moose in September-October, or a deer in November, will be far more active and vocal on crisp sub-freezing mornings. Pair a cold snap with the right period and you maximize your odds with calling.
Temperature cues
| Conditions | Game behavior |
|---|---|
| Prolonged warm spell | Reduced daytime activity, nocturnal game |
| Sharp 8-10 °C drop | Strong rise in daytime activity |
| First morning frosts | Intense morning and evening feeding |
| Biting cold and wind | Game bedded in shelter |
Tips
- Watch for warm spells followed by a plunge: that's your window.
- Be on stand very early on frosty mornings; activity peaks at first light.
- Dress in layers to stay still for long stretches without shivering.
- In extreme cold and wind, switch to still hunting along the shelter where game beds.
Cold wakes the game; it's up to you to be there when it moves.
