It would seem that a person either always thinks in terms of seasons, or never thinks in terms of seasons.
When Christine and I told people in the midwest that we were moving to the Caribbean, many people remarked "I bet it gets hot in the summer."
Well, no, because they don't have a summer.
When we tell people in Sint Maarten that we're from the Midwest, they ask if there's snow back home.
In the midwest it's hotter than it is in Sint Maarten, but if you don't understand seasons, all you know is that sometimes it snows there.
The problem here is trying to figure out just how hot is is.
I've been able to deduce that 30°C is warmer than is comfortable, and 20°C is a bit cooler.
More on this as it develops.
