Answer: Drier, warmer conditions
Drought risk rises across the southern tier.
- Q7: How does La Niña tend to affect Atlantic hurricane seasons?
Answer: It tends to make them more active
Weaker wind shear over the Atlantic helps storms develop.
- Q8: Which ocean region do forecasters watch to declare La Niña?
Answer: Niño 3.4 in the central Pacific
Temperatures at least 0.5 degrees Celsius below average signal La Niña.
- Q9: What was unusual about La Niña from 2020 to 2023?
Answer: It lasted through three winters in a row
Forecasters called it a triple-dip La Niña.
- Q10: How often do La Niña events typically occur?

They can last from several months to a few years.
La Niña Quiz – When the Pacific Runs Cool
La Niña, Spanish for the little girl, is the cool phase of the El Niño-Southern Oscillation. Sea surface temperatures in the central and eastern tropical Pacific drop below average, and the trade winds strengthen.
These changes shift rainfall worldwide. Eastern Australia and Indonesia often get heavy rain, as in the Queensland floods of 2010 and 2011, while the southern United States tends to be drier. Atlantic hurricane seasons are often more active.
Forecasters watch the Niño 3.4 region and declare La Niña when temperatures fall at least 0.5 degrees Celsius below normal. Events recur every two to seven years, and one lasted through three winters from 2020 to 2023.
