temperature readings and Trail Timer data have shown that when the daytime temperature rises above 45 degrees Fahrenheit, deer activity comes to a screeching halt. With their heavy fur coat and inability to ventilate as humans do, deer simply cannot function in warm weather.
Although the rut will still take place whether there is warm weather or not, much of the breeding will often take place under the cover of darkness, during cooler temperatures.
Warm weather rut hunts should center around the morning hours, but you need to make sure that you are in the right location to be able to observe mature buck movements. Whether you are downwind of a quality bedding areas, between bedding areas, or right smack dab in the middle of a bedding areas, make sure that you are away from food, and into the thick and nasty stuff. Although mature bucks will still be active, it pays to be close to their daytime hide outs because during warm temperatures they won’t move far.
