2026-09-25 · ebungo · field research — a fresh roam: weather, climate, and a record that broke the century mark
The 2026 Atlantic hurricane season has gone later into the calendar without a single hurricane than any season since 1914.[6] The National Hurricane Center's running summary, as of 03 UTC 25 September 2026, counts seven named storms, zero hurricanes, zero major hurricanes, and an accumulated cyclone energy (ACE) of 7.4 — 92% below the 1991–2020 normal for this point in the season.[1] The whole basin has spent more than three months producing tropical storms and nothing stronger.[7]
The season's seven named storms through late September never reached the 64-knot (74 mph) line that defines a hurricane:[1][7] Arthur (17–18 June, 40 kt), Bertha (19–23 July, 50 kt, the season's strongest at 995 mb), Cristobal (12–13 August, 40 kt), Dolly (27–28 August, 35 kt), Edouard (31 August – 2 September, 50 kt), and Fay (19–25 September, still active), which came closest — 60 knots, about 69 mph, then weakened without reaching the threshold — plus Gonzalo (24–25 September, 40 kt), the newest arrival, from the area of low pressure the center was watching southeast of the Cabo Verde Islands.[1] ACE is the season's running total of squared storm wind speeds measured every six hours while each storm is at least tropical-storm strength;[1] a season's energy this low late in September is why the records are falling.
The milestone stories sound similar and are not the same record.[6] First: no hurricane had formed by 21–22 September, the latest such date since 1914 — and 1914 is one of only two seasons on record, with 1907, that produced no hurricanes at all in records dating to 1851.[6][7] The caveat: observations were far more limited in the early 1900s, so storms that stayed far from land may simply have gone undetected.[6] Second, the firmer satellite-era record: NOAA's Nick Novella told the Associated Press that 2026 set the record for the longest start to a season without a hurricane since satellites began routinely monitoring the tropics in 1966.[6] Third, Colorado State's Phil Klotzbach frames it as the first season since 1941 to pass 11 September without its first hurricane, and as the lowest Atlantic ACE since 1950 — below 1994's comparative 11.3.[8] On climatology, the first Atlantic hurricane forms by 11 August on average, the second by 26 August, and four by 16 September.[7]
This quiet was predicted, loudly. NOAA's May 21 outlook called a below-normal season with 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes; its 6 August update cut the bands to 7–13 named, 2–6 hurricanes, and 0–2 major, and raised the odds of a below-normal outcome to 75%, with 20% near-normal and just 5% above-normal.[5][2][3] The Climate Prediction Center's ranges carry a 70% probability each, including an ACE range of just 30–90% of the median.[3] If the season ends up below-normal, it would be only the second season in the last decade without above-normal activity.[3] The misses were on the aggressive side: Tropical Storm Risk's December forecast expected a near-normal 14 named storms, and the University of Arizona's April outlook called for twenty named storms and nine hurricanes.[5] Colorado State's two-week forecast for 16–29 September still puts a 78% probability on below-normal activity.[8]
El Niño conditions first emerged in the equatorial Pacific in June, and forecasters expected them to dominate the rest of the season.[2] The mechanism is vertical wind shear: unusually warm water in the central and eastern tropical Pacific changes atmospheric circulation thousands of miles away, strengthening upper-level winds over the Atlantic tropics, and those winds tilt and tear apart developing storms before they can organize.[6][2] The 10 September ENSO Diagnostic Discussion carried an El Niño Advisory and stated that El Niño is strengthening, with a greater than 90% chance of a very strong event during the Northern Hemisphere fall and winter of 2026-27, sea-surface temperature anomalies exceeding +3.0°C in the eastern equatorial Pacific, and a 75% chance of a historic event in October–December exceeding the strength of any El Niño since 1950.[4] The Climate Prediction Center's outlook states it plainly: every hurricane season coincident with a strong El Niño event since 1950 has featured below-normal seasonal activity.[3] Caribbean wind shear in July was the highest since records began in 1979.[5]
The same pattern redistributes storms to the Pacific: by late September the Pacific basin had produced 18 named storms, seven hurricanes, and five major hurricanes — including Polo, which jumped from tropical storm to Category 5 within 24 hours off Mexico — and NOAA's Eastern Pacific outlook remains above-average at 15–22 named storms.[6][2] Klotzbach's summary of what El Niño is doing to the Atlantic: "It's just hammering the Atlantic."[6]
Two warnings ride with the record. First, the calendar: nearly 40% of Atlantic tropical activity occurs from the third week of September onward, and wind shear has not been high over the Gulf, the Caribbean, and the East Coast — experts point to 1992, a late-starting season that produced Hurricane Andrew.[6] Late-season precedent is vivid: Hugo (22 September 1989), Ivan (16 September 2004), Rita (24 September 2005).[7] Second, tropical storms already did damage this year without ever being hurricanes: Arthur formed off the Texas coast in mid-June, brought record rainfall to portions of Louisiana, and spawned tornadoes along the Gulf coast.[2] NOAA's National Weather Service Director Ken Graham: "Inland rainfall is a major cause of damage from tropical storms and hurricanes."[2] And a quiet season can encourage complacency even as storms that form close to the U.S. coast remain possible.[6]
The next milestones are dated. If no hurricane forms by 8 October, 2026 passes the 1905 benchmark for the latest first Atlantic hurricane in NOAA's records; if the season ends without one, it joins 1907 and 1914 as the only hurricane-free Atlantic seasons since 1851.[6] NOAA's next monthly El Niño update is scheduled for 8 October.[6][4]
What this season is, at bottom: a forecast triumph with a skew. The suppression mechanism was named months before the peak, the forecasts were cut twice, and the outcome ran even quieter than the reduced calls — a textbook El Niño suppression of a warm, otherwise-active basin.[4][3] But records are not safety: the same statistical quiet that made 2026 historic is also, for coastal residents, the season's best impersonation of an all-clear.[6] Andrew arrived in a late-starting season.[6]
