Tropical night

Okay kiddo, have you ever stayed up really late on a summer night, when it feels like it's still hot out even though it's dark outside? That's a bit like a tropical night, except even hotter!

A tropical night is a night when the temperature doesn't drop below 20 degrees Celsius (that's 68 degrees Fahrenheit) in the tropics. The tropics are the part of the world that's close to the equator, where it's always warm and sunny.

Now, you might wonder why this happens. Well, during the day the sun is really strong in the tropics, right? So everything heats up a lot. Even at night, that heat is slow to disappear. Plus, the air is often really humid (that means there's a lot of water in it), which makes it feel even hotter.

So, on a tropical night, it can be really hard to get to sleep because it feels so warm, even with a fan or air conditioning. But some people really like it – they say it makes them feel like they're in a tropical paradise!
