Why Do Cows Huddle Together When It Rains?

February 15, 2024

Every farmer who raises cattle has noticed that cows tend to huddle together while they are out on the pasture and in the barn. This behavior might seem random or strange to first-time farmers, but there are a few genuine reasons that cows like to group together.

One reason is that herd animals are innately compelled to stick together in times of stress, like bad weather or health issues. The herd’s collective support helps to alleviate the cows’ anxiety and reassure them that they are safe.

Another common theory is that cows huddle because they can sense the approaching rain through increasing air moisture or an accompanying drop in air pressure. This causes them to plop down to preserve a dry patch of grass for grazing, even though the cows themselves will not be affected by the rain.

But, as this Farmer’s Almanac article explains, there is no scientific evidence that cows are able to predict the weather. In reality, they might huddle for other reasons – such as seeking comfort, rumination process, or thermoregulation – that are not directly related to the occurrence of rain. Nonetheless, understanding the cows’ behaviors and why they may act in certain ways can help farmers to better care for them.
