NOAA Sees 81% Chance of Very Strong El Niño Through 2027 as Atlantic Storm Risk Eases

Q: As El Niño strengthens, is 2027 destined to be the hottest year ever recorded?

No. But 2027 is increasingly likely to challenge or break the global heat record. The reason is the timing and strength of El Niño. NOAA says the event is now established, is expected to last through the 2026 hurricane season, and is highly likely to continue into early spring 2027, with an 81% chance of becoming “very strong” by late 2026. Historically, El Niño tends to lift global average temperatures by roughly 0.2°C, and its strongest effect on global temperatures often shows up in the year after it develops. That puts 2027 in the prime window. Major forecasting centers are signaling elevated odds of a record year. The World Meteorological Organization has said an El Niño developing late in 2026 raises the chances that 2027 becomes the next record-breaking year. Some model guidance cited in recent reporting puts the probability of 2027 being the warmest year on record at around 85%. What makes this especially important is that El Niño is adding heat on top of long-term human-caused warming. Scientists stress that El Niño itself is natural, but it now operates in a much warmer climate background, increasing the chance that temporary El Niño warmth pushes global temperatures to new highs. Still, “destined” is too strong. Long-range climate forecasts are probabilistic, not certain, and other ocean-atmosphere factors can still affect the final outcome. The best evidence points to 2027 being a leading candidate for the hottest year ever recorded, not a guaranteed one.

NOAA said El Niño is now firmly established and is expected to last through the entire 2026 Atlantic hurricane season, with a 97% chance it persists into early spring 2027.
81% odds that 2026 ends with a very strong El Niño reflect recent Pacific warming, which boosts Atlantic wind shear and suppresses tropical storm development.
Colorado State University this week cut its seasonal outlook to 9 named storms and 4 hurricanes, pointing to what could be the quietest Atlantic season in a decade.
South Florida could see the opposite effect in winter: a cooler, wetter pattern, more storminess and higher severe-storm risk if El Niño holds through next April.
The last robust El Niño winter, in 2015-16, brought record January rainfall across parts of South Florida after a relatively quiet hurricane season.

Strongest El Niño on Record? NOAA’s 2026 Forecast and the Looming Global Crisis

Overview

NOAA’s latest forecast warns that a strong El Niño is likely to develop by autumn 2026, with eastern Pacific waters continuing to warm. This event could be among the most powerful ever recorded, but its exact impacts remain uncertain because each El Niño is unique in timing, strength, and reach. El Niño-Southern Oscillation (ENSO) is the main driver of year-to-year climate variability, influencing global weather through atmospheric teleconnections that can trigger floods, droughts, and extreme rainfall. As a result, the upcoming El Niño could reshape weather patterns worldwide, with effects that depend on many changing factors.
