Powerful El Niño Triggers Record-Quiet Atlantic Hurricane Season While Pacific Surges

POLICY WIRE — Washington, United States — The Atlantic basin is experiencing a historically quiet hurricane season as an enormous El Niño effectively crushes storm systems before they can develop. According to the National Hurricane Center, zero Atlantic hurricanes have formed so far this year, and none are projected to materialize for at least another week, even during what is normally the peak of the season. The official season spans from the beginning of June through the end of November, typically reaching its height between August and October. Thus far, only five relatively weak and brief tropical storms have managed to spin up.

Nick Novella, a meteorologist at the government’s Weather Prediction Center, noted that Saturday marked a modern satellite-era record for the longest time a season has gone without producing a storm reaching the 64 mph winds required to qualify as a hurricane. While historical archives indicate a few pre-1950 years recorded no hurricanes this late in the calendar, meteorologists remain skeptical of those older logs due to incomplete ocean monitoring systems.

Colorado State University hurricane expert Phil Klotzbach pointed out that hurricane activity—measured by storm frequency, intensity, and duration—is sitting at a post-1950 record low. Atlantic storm activity currently measures a mere 7% of normal levels for this time of year, falling well short of the nine named storms projected by Colorado State University researchers in their annual 2026 outlook.

Atmospheric science experts warn that the public must remain vigilant, emphasizing that it takes only a single storm to cause catastrophic damage, even amid a subdued El Niño cycle. Several researchers highlighted the 1992 season, which started slowly before unleashing the destructive Hurricane Andrew, and noted that lower-power storms can still present severe hazards.

Kristen Corbosiero, an atmospheric science professor at the University at Albany, described the Atlantic environment as staggeringly inhospitable to tropical cyclones. Any developing system currently faces a triple threat of winds that decapitate storms, dry air that starves them, and downward-pushing air currents that suppress formation.

These three disruptive forces stem directly from El Niño, a temporary and natural warming of equatorial Pacific waters that alters global weather patterns. Five experts confirmed to the press that the phenomenon, which recurs every two to seven years, last appeared in 2023. Klotzbach emphasized the sheer intensity of the current cycle, noting that nothing even remotely approaching hurricane strength has developed in the basin.

The primary driver of the suppression is record-strong wind shear across the Atlantic, occurring when low-level easterly winds collide with upper-level westerly winds moving in the opposite direction. Corbosiero explained that these opposing currents tear developing storms apart. In the main development corridor stretching from Africa to the Caribbean, this wind shear exceeds a tropical cyclone’s structural limits by roughly 45 mph, creating an unprecedented hostile environment.

University of Miami hurricane expert Brian McNoldy illustrated the effect by stating that storms are having their heads cut off before they even get a chance to form. Corbosiero and other researchers cautioned that the Gulf of Mexico remains the sole exception where wind shear has stayed low, leaving open the possibility of strong late-season storms in that specific sub-region.

Experts added that African dust is further choking developing systems alongside the aforementioned dry air, while the atmospheric conditions feature fewer initial weather seeds capable of growth. High-pressure systems across the Atlantic are also forcing air downward to further hinder cyclonic development. Klotzbach observed that El Niño’s suppressing power is prevailing even against record-hot global ocean waters that have persisted for 100 days—conditions that would normally fuel intense storm activity.

Massachusetts Institute of Technology meteorology professor Kerry Emanuel explained that Atlantic waters have not warmed as rapidly as the overlying atmosphere, which heated up swiftly due to El Niño. Emanuel’s research indicates that the temperature differential between the air and water dictates storm potential more than absolute water temperature alone, as hurricanes draw power from the heat flow moving from ocean to air. A smaller gap results in diminished storm activity.

Emanuel added that Atlantic waters lag a few months behind the atmosphere in absorbing El Niño’s impact. Next year, as El Niño subsides and temperatures drift back toward normal, the lingering warm ocean waters will likely elevate the probability of an exceptionally active upcoming season.

Conversely, while El Niño dampens the Atlantic, it actively revives tropical cyclone activity in the Pacific by introducing moist air and minimal wind shear. Eastern Pacific storm activity has nearly doubled normal levels this year, featuring unusually long-lasting hurricanes, while central Pacific activity sits roughly 40% above historical averages. Klotzbach remarked that conditions in the eastern Pacific resemble a continuous succession of storms.

While the Atlantic counts only five minor tropical storms, the eastern Pacific has recorded 16 named storms and the central Pacific has seen 20. Hawaii has already endured two direct impacts. Hurricane Lowell struck the western islands last week, triggering widespread power outages on Kauai, where the small community of Hanalei recorded 17.76 inches of rainfall. In August, Hurricane Lala passed 30 miles off the Big Island’s coast, unleashing torrential rains and wind gusts exceeding 80 mph while destroying roughly 100 homes and causing extensive power failures, despite not making an official landfall.

Corbosiero noted that El Niño typically guides storms further west than usual during comparable years. Although forecasters anticipated a subdued Atlantic season months in advance due to well-documented historical patterns linking El Niño to storm suppression, McNoldy admitted that the absolute quietness exceeded all expectations, calling the current outcome remarkable.
