Okay, kiddo. So, you know how birds and some animals travel from one place to another depending on the time of year? Well, humans also do this too! It's called seasonal human migration.
When the weather gets too cold, some people move to a warmer place for a while. They might go to a place where the sun shines more often and the temperature is not too chilly. This is called winter migration.
On the other hand, some people go where it's cooler when it gets too hot. They go to places where the weather is more comfortable and enjoyable. This is called summer migration.
Some people may migrate for work too, like farmers who move from one place to another depending on the farming season.
However, unlike birds and animals, people don't usually fly or walk to their destination. They use cars, planes, buses, or even boats!
So, kid, that's what seasonal human migration is all about. It's when people move from one place to another depending on the time of year, just like some birds and animals.
