What does El Nino mean for Colorado?
For Colorado, you may notice that the strongest signal shows up in wintertime temperature anomalies during an El Niño, when the entire state is likely to experience overall below average temperatures. During a La Niña, the eastern plains are more likely to see above average temperatures in the winter and summer.
Will El Nino return in 2021?
The tropical Pacific has been ENSO-neutral since May 2021, based on both oceanic and atmospheric indicators.

How does El Nino cause disease?
It can be a bit complicated, but the short answer is that the temperature and precipitation patterns driven by ENSO can alter the habitat of disease transmitters, such as mosquitoes or rodents, or make conditions more conducive for waterborne diseases, such as cholera.
