January had the third-highest number of tornado watches and confirmed tornadoes of any January on record in the United States, behind 2017 and 1999. The first two months of the year had the fourth-highest number of confirmed tornadoes for the first 59 days of any year on record.

The year was deadlier than average, with a number of fatal tornadoes. By April 5, 63 tornado-related deaths were recorded in the United States; this was almost three times higher than 2022's total of 23 fatalities, approaching the annual average of roughly 70 deaths (17 of which came from a single EF4 tornado in Mississippi on March 24). Below-average tornadic activity occurred in May; however, active weather patterns spawned damaging tornado outbreaks throughout the summer, resulting in 12 additional fatalities. Damaging tornadoes also affected parts of Canada during that time, including the country's first violent tornado since 2018 (on July 1). Tornadic activity decreased abruptly in September, and tornadoes were almost non-existent during much of the autumn. Most Atlantic tropical cyclones missed the United States during the peak of hurricane season, with few early-season frontal systems; however, an intense outbreak in December produced 18 tornadoes, causing seven fatalities, all 7 of which occurred in Tennessee.

Several European organizations, including the European Severe Storms Laboratory and Deutscher Wetterdienst, officially began publishing and using the new International Fujita scale in late July 2023. The first major tornado outbreak using the scale occurred three months later, when Storm Ciarán affected much of Europe.

Events

United States

There were 1,423 reported tornadoes and 1,379 confirmed tornadoes in the United States in 2023.

  • Note: An EFU tornado from the United States crossed into Canada, where that portion of the track was rated EF1. This is counted as an EF1 tornado since it is one continuous tornado.
