Need Ideas

We call them tourists.

Crazy?

lol We call them neighbors cause most of them are.

I agree with @Morleyhunt, I call them "tourists", we have plenty in Summer here.

I thought all the people that came North lived here too start with. We get a lot of visitors here but they are from all over not just the hotter southern States

When you say "North" do you mean Alaska and/or other northern territories? Because in the northern USA at the border and into Canada, it is just as hot and humid in summer as it is in Florida. Coming here in summer to escape the heat and humidity is futile. You'd need to fly SOUTH, like to Brazil or Australia to get some cool relief of the heat.

I'd call them visitors.

Let me know when you get a really great idea! LOL!!!! I'll always consider myself a New Englander.

Tourists.

In Australia, they are all called grey nomads.

Smart? LOL.
