September Ends 30‑Year Streak of Atlantic Hurricanes Amid El Niño Concerns

In an occurrence not seen for about thirty years, the Atlantic basin finished September with zero hurricanes, shattering a trend that has traditionally made the month the most active segment of the yearly storm cycle.

September has long contributed the bulk of named storms and hurricanes; climatology indicates that over 50 % of Atlantic hurricanes attain their maximum strength in that month. The complete lack of a hurricane this September is striking when viewed against a steady record of activity that has continued since the early 1990s.

Researchers attribute much of the quiet to the current El Niño episode. This warming of the central and eastern Pacific typically elevates wind shear across the Atlantic, a factor that hampers both the birth and strengthening of storms. Although El Niño alone does not ensure a calm season, its role in curbing Atlantic hurricane counts is well established.

Still, meteorologists warn that the season is not finished. August saw a handful of tropical storms, and the atmospheric setup that has held back hurricanes may change as El Niño weakens. October has traditionally delivered another spike in activity, leaving the door open for late‑season storms, particularly if sea‑surface temperatures remain elevated and wind shear diminishes.

This rare September calm highlights how difficult seasonal forecasts can be. Although climate models factor in El Niño’s suppressive impact, the inherent variability of tropical cyclones forces forecasters to keep their outlooks adaptable. Emergency officials and coastal dwellers should remain ready for potential storms later in the year, despite the present data indicating a quieter than normal month.
