El Niño is a weather phenomenon that occurs in the Pacific Ocean.
It happens when the ocean's surface temperatures rise above average for an extended period of time.
El Niño can affect weather patterns around the world, including causing droughts, floods, and hurricanes.
While El Niño is often associated with colder temperatures, that's not always the case.
In fact, El Niño can sometimes cause warmer temperatures in certain regions.
The effects of El Niño can last for several months to a few years. Scientists are still studying El Niño to better understand its causes and effects.
