Why do cattle huddle together in hot weather?

Answer 1

Cattle huddle together in hot weather because they can sense when a storm or rain is coming. Cattle are usually huddled around a water hole in hot weather.

Actually, the real reason cattle may be huddled together in hot weather is because they may be stressed and are grouped up tightly together as a form of comfort for each animal, especially when harried by dogs or when they are about to be moved from one pasture to another. Cattle are social animals and will naturally stick together no matter how hot or cold it is outside, but they won't stick so close together that they are huddled, because that can create heat exhaustion for animals sharing each other's warm bodies during a time when sharing each other's warmth is the last thing they want to do.
