Super El Nino: What it is, why it matters, and how it can impact North Carolina weather
A super El Niño began building in late September 2026 and is projected to be the strongest on record. Defined by a 3 to 4 degree Fahrenheit warming of the tropical Pacific Ocean, this event is expected to break all previous sea-surface temperature records. Impacts include potential global weather disruption, though some regions of the U.S. may see drought relief. In North Carolina, cities like Raleigh and Charlotte face a 25% increase in projected rainfall and a primary risk of flooding between December and March.

In North Carolina, cities like Raleigh and Charlotte face a 25% increase in projected rainfall and a primary risk of flooding between December and March.
Why it matters
El Niño is a natural climate cycle where Pacific sea-surface temperatures and atmospheric circulation shift between warm, cool, and neutral phases. A super El Niño is an unusually intense version of this warming that can reshape global weather for months. This specific event is fueled by record Pacific wind anomalies.
