Tropical regions can experience surprising cold weather.

During winter, cold air can push south from the polar vortex, affecting places like Atlanta and the Gulf of Mexico.

In South Florida, Miami usually has January highs in the 70s, but it can drop to 28 degrees, as it did in a 1977 snow event that caused $300 million in crop damage.

Heroica Veracruz in Mexico sees temperatures in the 30s due to cold air damming from mountains.

Even the Sahara Desert can experience freezing temperatures, like in Dongola, Sudan, when cold air moves south.

These examples show that tropical areas can face unexpected cold weather. https://www.accuweather.com/en/climate/3-surprising-places-in-the-tropics-that-have-had-freezes/1711904
