El Niño May Reshape the Next Hurricane Season

Clear Facts

• The National Oceanic and Atmospheric Administration says La Niña is fading as neutral conditions take over.
• Forecasters predict a powerful El Niño may develop during the peak of the 2026 hurricane season.
• El Niño typically suppresses Atlantic tropical activity by increasing upper-level wind shear that disrupts storm formation.

Climate models from the International Research Institute for Climate and Society now project equatorial Pacific temperatures reaching 1.5 degrees above average by October.

This significant increase suggests a much stronger El Niño than earlier forecasts indicated for the coming year.

While El Niño usually reduces the number of named storms, history shows individual systems can still threaten American coastal communities.

High sea surface temperatures in the Atlantic can sometimes offset the suppressive effects of wind shear.

In 1992, Hurricane Andrew caused over $25 billion in damage despite occurring during an El Niño year.

More recently, the 2023 season became the fourth most active on record due to record-warm ocean waters.

The timing of this climate shift is critical for emergency preparedness and seasonal expectations.

If the transition happens rapidly by mid-summer, tropical activity could be limited during the most dangerous months of the year.
