2026年大西洋飓风季出现罕见现象，9月整月未形成任何飓风，这是30多年来的首次1。截至9月中旬，整个赛季仅记录四场命名风暴——爱德华、费、贡萨洛和汉娜——远低于美国国家飓风中心5月份预测的八到14场命名风暴1。若这一趋势持续，2026年将成为卫星时代以来首个无飓风的大西洋飓风季1。根据记录，自1914年以来就没有出现过整年无飓风的情况1。
强厄尔尼诺现象是这一异常现象的主要原因1。厄尔尼诺通过增加大西洋风切变来抑制飓风形成，同时导致太平洋活动异常活跃1。太平洋地区中部和东部的温度纪录已被打破，日均海面温度超过2015年的记录1。本季太平洋盆地已形成17场命名风暴，其中包括9场飓风，7场为超强飓风1，该地区累积气旋能约为正常水平的两倍半1。厄尔尼诺现象预计将在11月或12月达到峰值1。
The 2026 Atlantic hurricane season has marked an unprecedented milestone, with no hurricanes forming throughout September for the first time in more than 30 years 1. As of mid-September, only four named tropical storms—Edouard, Fay, Gonzalo, and Hanna—had developed in the Atlantic basin 1. If current conditions persist, this could become the first Atlantic hurricane season in the satellite era to end without producing a single hurricane 1.
The exceptional lull has been driven by a strong El Niño phenomenon, which increases wind shear across the Atlantic and suppresses hurricane formation 1. Meanwhile, this same atmospheric pattern has fueled extraordinary activity in the Pacific basin, where 17 named storms have formed, including nine hurricanes with seven reaching major status 1. Sea surface temperatures in the central and eastern Pacific have shattered records, with daily readings exceeding those recorded during the 2015 El Niño event 1. Accumulated Cyclone Energy this season is running at approximately two and a half times above normal levels 1, with El Niño predicted to peak between November and December 1.
The contrast with seasonal forecasts is stark. The US National Hurricane Center predicted in May that the Atlantic would experience between eight and 14 named storms, with three to six developing into hurricanes 1. If the season concludes without any hurricanes, it would represent a historic break from records extending back to 1914, when monitoring began prior to the satellite era 1.
