What are extreme temperature fluctuations?

Extreme temperature fluctuations are when it gets super hot one day and super cold the next, like going from a sunny beach to an icy freezer in just a few hours.

Imagine you're playing with your favorite toy, and suddenly it's so hot outside that you want to eat ice cream. But then, by nightfall, it's so cold you need a blanket to stay warm. That’s extreme temperature fluctuations, when the weather changes really fast and really much.

Think of the weather as a roller coaster. One moment you're zooming up high (that’s hot), and the next you’re plunging down low (that’s cold). It's like riding a roller coaster without a seatbelt, you feel every big drop and climb!

Some places, like parts of Canada or Russia, have extreme temperature fluctuations all year. In the morning it might be snowy and freezing, but by afternoon, the sun comes out and melts the snow, making it warm enough to play outside barefoot.

It’s not magic, just a big difference between hot and cold happening really quickly!
