Madrid, May 15 – This past Tuesday marked 140 years since a powerful tornado devastated parts of central Madrid in 1886. This event, considered one of the “most intense documented in Spain,” caused numerous fatalities and extensive damage, though a repeat of such a phenomenon is considered unlikely by the State Meteorological Agency (Aemet).
The 1886 Madrid Tornado: A Historical Overview
“The 1886 tornado in Madrid began in Carabanchel Alto and traveled northeast for 12 to 18 kilometers, reaching a maximum width of up to 1 kilometer,” explained José Ángel Núñez, spokesperson for Aemet, to EFE. Núñez highlighted that while tornadoes are not frequent in Spain, several occur annually, typically small in scale and across all seasons.
Coastal areas, particularly the Mediterranean, experience more frequent tornadoes in autumn or late summer. In contrast, the Atlantic coast and adjacent plains see higher frequency during colder months. Inland Peninsular areas, though less frequent, can experience more intense tornadoes, usually in late spring and summer, driven by “strong thermal instability and significant wind shear,” conditions present during the 1886 event.
Manuel Mora García, an Aemet meteorologist, noted that May 12, 1886, saw “extraordinary convective activity in the central peninsula, with storms, intense rain, hail, very strong wind gusts, and even tornadoes, like those that affected Madrid and probably Guadalajara.”
Devastating Impact and Unclear Casualties
The tornado left a grim toll. “The balance in the capital was dozens dead, over a hundred injured, and extensive material damage,” said Mora García. The exact number of fatalities remains debated, but a 2007 study published in the journal Atmospheric Research suggests “the tornado caused around fifty deaths,” according to eltiempo.es.
Mora García, in his Aemet blog, documented “significant damage” in the areas of Madrid affected by the tornado. This included damage to the Casón del Buen Retiro, various buildings, and the Royal Botanical Garden, where many centuries-old trees were completely destroyed.
Probability of Recurrence and Detection Challenges
Núñez stated that in climatology, “return periods or recurrence periods” are used to explain that a past phenomenon will repeat in the future with similar or greater intensity. However, he added, “these extreme phenomena have recurrence periods of several decades; so it could happen again, although it is unlikely.”
Tornadoes are micro-scale phenomena, making their detection and measurement of maximum gusts very challenging, especially without a sufficiently dense network of observatories. “This is still true in 2026, so one can imagine how difficult it would have been in 1886,” Núñez emphasized.
Despite these challenges, field studies can often be conducted to deduce “with a high degree of reliability that a tornado was responsible for identified damage and to estimate its speed.” According to the Enhanced Fujita Scale, used globally since 2007, the 1886 Madrid tornado likely reached category EF3, meaning maximum gusts could have ranged between 219-266 km/h.
Tornadoes of this intensity are more common in the east-central parts of Spain, particularly in the Maestrazgo region of Teruel, often in “very sparsely populated areas, and many go unnoticed.”
