Only about 10% of the human population lives in the southern hemisphere. That doesn't necessarily justify it, but it's far from 50/50.

I am in the tropics on the equator and the concept of 4 seasons is meaningless here.

At least when I was in New Zealand I could just inverse the seasons to see what USA based companies and people were talking about when they referenced their seasons. Now I have to do a mental calculation (which is hard to remember, as as I said, you don't get seasons here at all) to work out time frames when people are talking about stuff like this.

A decent chunk of the population of the planet (most of it, I think?) lives around the equator
