As of the current moment, the Atlantic hurricane season has seen only six named storms, with most of them being short-lived. The question arises: Why is there a lack of hurricane activity? Phil Klotzbach, a senior research scientist at Colorado State University, attributes this phenomenon primarily to the strong El Niño event currently taking place.
El Niño, a part of the El Niño-Southern Oscillation (ENSO) natural cycle, involves the central Pacific Ocean’s water and atmospheric winds. When the water temperature rises 0.5°C above average within a specific timeframe, it signifies an El Niño event. Conversely, a temperature drop of -0.5°C below average indicates a La Niña event, with global impacts.
The ongoing El Niño event has led to an advisory with models predicting potentially historic anomalies. The Climate Prediction Center’s meteorologist, Lindsey Long, anticipates anomalies exceeding the previous record set in 1982 and 1983. This robust El Niño event has significant chances of being unprecedented in strength.
In the Atlantic basin, the subdued hurricane season was forecasted earlier by NOAA, attributing it to the El Niño effect. The warmer sea surface temperatures in the eastern Pacific create vertical wind shear in the Atlantic, disrupting the formation of hurricanes due to unfavorable wind conditions.
Despite the quiet Atlantic season, there remains a slight possibility for hurricane formation, particularly in the warm Gulf of Mexico. However, the chances are minimal due to prevailing wind shear conditions. Meanwhile, the Pacific Ocean has experienced heightened hurricane activity, with 16 named storms reported so far.
While the lack of hurricanes in the Atlantic can be linked to the current El Niño episode, some tropical storms have impacted Gulf communities. The El Niño is expected to reach its peak in late 2026, extending into 2027. The implications for the next hurricane season remain uncertain, as post-El Niño years typically see a warmer Atlantic but no El Niño, affecting future hurricane forecasts.
