List of weather records

List of weather records

This is a list of weather records, a list of the most extreme occurrences of weather phenomena for various categories. Each of these is understood to be the record for recent history, as these records may have been exceeded before modern weather instrumentation was invented.


Highest temperature ever recorded

Other cold records

*Fastest temperature drop: 26 C° (47 F°) in just 15 minutes; Rapid City, South Dakota, 1911-01-10.


*Least per year (locale): 0.00 mm (0.00 in/year), none in recorded history; Antofagasta Region, Atacama Desert, Chile. [ [ Atacama Desert @ National Geographic Magazine ] ]


*Most in one minute: 3.8 cm (1.5 in); Barst, Guadeloupe, 1970-11-26.
*Highest average annual total: 13.3 meters (523.6 in); Lloro, Colombia. [ - 101 Amazing Earth Facts ] ]

*Fastest daily average: 174 km/h (108 mph); Port Martin (Adélie Land), Antarctica.


Deadliest in history

*On Earth: Approximately 1300 deaths; Manikganj District, Bangladesh on 1989-04-26. [ Tornadoes in Bangladesh ] ]
*In North America: 695 deaths (Tri-State Tornado); Missouri, Illinois, Indiana, United States 1925-03-18.
*In Europe: 600 or more (Grand Harbour Tornado); Valetta, Malta, 23 September 1551 or 1556 (sources conflict) [ TORRO: Research: Tornado Extremes ] ]

Earliest known

*On earth: 1054-04-30; Rosdalla (near Kilbeggan), Ireland.


*Deadliest: 747 were killed by the Tri-State Tornado and associated outbreak on 1925-03-18.
*Largest and most severe: 148 tornadoes occurred in 16 hours on 03 April to 04 April 1974. They affected 13 US states and Ontario, Canada, and included 24 F4's and 6 F5's, more F5's than have been reported in any other "year". There were also more significant tornadoes during that 24 hours than any other entire week on record.

Tropical cyclones

Most intense (by minimum surface air pressure)

*Most intense ever recorded: 870 mb (25.63 inHg); eye of Super Typhoon Tip over the Pacific Ocean, 1979-10-12.
*Most intense in the Western Hemisphere: 882 mb (26.05 inHg); eye of Hurricane Wilma, 2005-10-19. [ Tropical Cyclone Report ] ]
*Most intense ever recorded on land: 892 mb (26.35 inHg); Craig Key, Florida, eye of the Labor Day Hurricane, 1935-09-02. While other landfalling tropical cyclones have almost certainly had lower pressures, data is spotty from areas other than the Atlantic Basin, especially before the invention of weather satellites.
