understanding el niño and la niña
El Niño and La Niña are opposite phases of the El Niño-Southern Oscillation (ENSO) cycle, which significantly influences global weather. These phenomena are characterized by anomalies in sea surface temperatures in the Pacific Ocean.
el niño occurs when ocean surface temperatures become warmer than average, leading to various climatic impacts such as increased rainfall in certain areas and droughts in others. Conversely, la niña is marked by cooler-than-average ocean temperatures, often resulting in different weather patterns including colder winters and more hurricanes.
- El Niño effects: droughts, floods, temperature increases
- La Niña effects: colder temperatures, increased hurricane activity, heavy rains
current status of la niña predictions
The National Oceanic and Atmospheric Administration (NOAA) had initially predicted that La Niña would develop soon after the last El Niño event ended in 2024. However, as of January 2025, La Niña has yet to manifest.
Recent updates suggest only a 59% chance of La Niña developing imminently. Current conditions show the Pacific’s equatorial waters are near average temperatures but still not meeting the criteria for an official La Niña event. If it does occur before the end of January, it might last until March at most, potentially rendering its impact on global climate negligible.
a neutral phase possibility for 2025
If La Niña fails to establish this year, a neutral ENSO phase might persist throughout 2025. Neutral phases typically result in warmer global temperatures due to lack of cooling effects that accompany La Niña events.
- A neutral phase could mean sustained higher-than-average summer temperatures.
- The ongoing impact of climate change could exacerbate these warmer conditions.
The last significant neutral phase occurred between spring 2012 and fall 2014. Such extended periods without a distinct ENSO signal are rare but can have profound implications for climate trends globally.
