La Niña has fizzled out, data released Thursday shows. According to the Climate Prediction Center, temperatures in the central and eastern equatorial Pacific have returned to near-normal. And, according to a technical definition, La Niña never truly developed.  The outlook for La Niña became progressively weaker over the past half year. In October 2024, experts predicted that La Niña would emerge during the fall. After months of delay, officials announced in January that La Niña conditions had finally arrived, with below-average sea surface temperatures in the Pacific. But those temperatures didn’t hold.  The Climate Prediction Center update calls for neutral conditions — neither La Niña nor El Niño — for the coming months. That means different climate patterns, some of which are harder to anticipate than La Niña, could have outsize effects on California weather in the coming months.
