Take a look at these skies over the California. Dark clouds, bursts of sunshine, passing showers, and an atmosphere that feels unusually energetic for late spring. While these clouds are not being caused by El Niño itself, they arrive at a time when meteorologists are closely watching significant changes taking place across the Pacific Ocean.

Current forecasts indicate that El Niño is likely to begin developing during the coming months. The strongest impacts are not expected until late fall and winter, but the atmosphere does not wait for an official declaration before it begins responding to larger scale changes. Long before California sees the full influence of El Niño, we can experience periods of increased atmospheric instability, more dramatic cloud formations, occasional thunderstorm opportunities, shifting weather patterns, and brief surges of moisture and humidity.

That is why weather experts are paying attention to what is happening right now. This summer is still expected to be near to slightly warmer than average across much of California. However, there may be more episodes of unsettled weather, isolated thunderstorms, and unusual sky conditions than people typically expect this time of year.

The more noticeable signs of El Niño’s influence could begin appearing by late summer and fall as ocean temperatures continue warming across the tropical Pacific. If the pattern develops as forecast, the period from December 2026 through March 2027 could bring an increased risk of atmospheric rivers, stronger Pacific storms, heavier rainfall, flooding, landslides, coastal impacts, and above average Sierra snowfall.

No one can say exactly how strong this El Niño will become. What we do know is that the Pacific Ocean is changing, and the atmosphere is beginning to respond. These dramatic skies serve as a reminder that California’s weather is constantly evolving, and the next chapter may already be starting to unfold above our heads.
