Deer are not significantly affected by rain, and they will continue to go about their business as usual. In fact, rain can actually make deer more active, especially after a heavy rain event ends when they may be hungry and eager to move. Heavy rainfall can also be an ideal time for deer to travel from one place to another without being detected by predators. However, harsher downpours accompanied by strong winds may send deer into hiding. When seeking shelter, deer usually find an outcropping or ridge to hide under, but they are always well-positioned to stay on the lookout for predators. Therefore, if you are hunting deer in the rain, it is important to be prepared with the right gear and anticipate a longer sit than you normally would. Additionally, it is important to consider the implications on a blood trail, as rain can make it harder for a human to track blood.
