The majority of recorded tornadoes in the world occur in the United States. This is somewhat misleading, however. The actual number of tornadoes occuring outside the United States is probably much higher than records indicate. Many countries do not conduct surveys or keep detailed records, so many of the less damaging tornadoes and tornadoes that occur in sparsely populated areas are never recorded. It is quite possible that thousands of tornadoes go undocumented every year.

It varies widely. Tornado distribution is not even throughout the year and many days go without any tornadoes. The most tornadoes recorded in 1 day is 207 on April 27, 2011. Many tornadoes occur in outbreaks, like this, only smaller. However, for the U.S. given that it has about 1,200 tornadoes in an average year and each year has 365 days, the works out to a mean 3 to 4 tornadoes per day
HIgly dangerous tornadoes can strike at any time of day or night, but they are most common between the hours of 4 pm and 9 pm. Tornadoes at night tend to be more dangerous because they are difficult to see.
