Q. Does the eastern Pacific Ocean get warmer or cooler?
During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual. That change is intimately tied to the atmosphere and to the winds blowing over the vast Pacific.
Q. Is the eastern equatorial Pacific warmer or colder than average right now?
The region of colder than normal waters in the eastern equatorial Pacific is called the ENSO region and is currently in a weak negative (cold) phase. Take note of the cold anomalies developing in the North Pacific, along the west coast of the United States and Canada.

Q. When the eastern Pacific Ocean gradually warms more than normal resulting in an increase of precipitation we call this what?
El Niño is a warming of surface waters in the eastern tropical Pacific Ocean. Together with, La Niña, these make up two of the three states of the constantly changing El Niño/Southern Oscillation (ENSO) that can affect weather patterns around the globe.
Q. What’s normal climate in the Pacific Ocean?
Normally, sea surface temperature is about 14°F (8°C) higher in the Western Pacific than the waters off South America. This is due to the trade winds blowing from east to west along the equator allowing the upwelling of cold, nutrient rich water from deeper levels off the northwest coast of South America.
Q. Is 2020 a strong La Nina?
2020 stands out, following a winter where tropical Pacific sea surface temperatures were slightly warm, but not quite El Niño.
Q. Does La Nina make it warmer?
During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North. La Niña can also lead to a more severe hurricane season. La Niña causes the jet stream to move northward and to weaken over the eastern Pacific.
Q. Will there be an El Nino in 2021?
The La Niña conditions that characterised the late part of 2020 and early 2021 have abated, with the majority of forecasts for El Niño/La Niña suggesting that neutral conditions will persist for the remainder of 2021.
Q. Would a La Nina event have a negative impact on wildlife?
Yes. Explanation: In the tropical Pacific, like the western coast of central and south America, the surface of the sea is cooler than normal and that results in reduced rainfall, drought and increased fires. This definitely brings about a negative effect on wildlife, as there is less water and food available.
Q. Is El Nino or La Nina worse?
A La Nina usually means a more active season with more and perhaps stronger storms. An El Nino means fewer, weaker storms. An El Nino means more strong crosswinds that can decapitate storms, but a La Nina means fewer, allowing storms to grow.
Q. Is La Nina coming?
La Niña conditions have ended and NOAA forecasters estimate about a 67% chance that neutral conditions will continue through the summer. The ENSO forecast for the fall is less confident, with odds of a second-year La Niña currently hovering around 50–55%.
