How long do the La Niña events last in years?

Episodes of El Niño and La Niña typically last nine to 12 months, but can sometimes last for years. El Niño and La Niña events occur every two to seven years, on average, but they don't occur on a regular schedule. Generally, El Niño occurs more frequently than La Niña.

Why is it getting colder 2021?

One reason for cooler temperatures in 2021 was likely La Niña, a band of cold water in the Pacific. It's the product of strong trade winds that scour the ocean, pushing the top layer of water toward Asia, causing deeper, colder waters to rush to the surface to fill the void.
