Not necessarily. Tornadoes can form in most climates, but they depend on thunderstorms in order to form, which require moisture. The most tornado-prone region in the world is located on the Great Plains of the U.S., which have a relatively dry climate, but truly arid regions rarely see tornadoes. Tornadoes are not uncommon in the southeastern U.S., which has a moist climate.
Deserts are prone to a type of whirlwind called a dust devil. Dust devils occur on sunny days and can look somewhat like tornadoes, but they are much weaker and are usually harmless.

Can tornadoes cause a dry period?
While tornadoes can form in a variety of different climates including those which are wet and/or dry, there is no causal relationship between tornadoes and the creation of dry environments.
Do all tornadoes have to have rain?
No, tornadoes do not always have associated rain. Tornadoes can form in dry conditions, known as "dry tornadoes," where there may not be any rain falling in the immediate vicinity of the tornado.
What causes tornadoes dry climates stationary fronts condensation or wind shears?
Condensation and wind shear are both needed for tornadoes to form. Tornadoes can form along stationary fronts as well.
Why doesn't Arizona get tornadoes?
Arizona's weather conditions are not conducive to the formation of tornadoes. Tornadoes typically form when warm, moist air collides with cool, dry air, creating instability in the atmosphere. Arizona's dry climate and topography do not support the conditions needed for tornado formation.
In what seasons do tornadoes form?
Tornadoes can form in any season, but they are most common in the spring and early summer when warm, moist air masses collide with cool, dry air masses. These conditions create the instability needed for the formation of tornadoes.
What is the climate when tornadoes do form?
Tornadoes typically form in conditions where warm, moist air at the surface meets cool, dry air aloft. This creates instability in the atmosphere, which can lead to the development of severe thunderstorms and tornadoes. High wind shear and a lifting mechanism, such as a cold front or dry line, are also important factors for tornado formation.
How come tornadoes go some places more often but not others?
It depends on the location. Tornadoes usually occur in dry areas with alot of dust, such as a prairie
Do tornadoes form at the boundaries?
Very often they do. Tornadoes typically form along from thunderstorms that occur along or near a cold front (where cold air pushes into warm air) or dry line (where dry air pushes into moist air). However tornadoes can also form in the absence of boundaries such as in the outer rain bands of a hurricane.
What do tornadoes form along?
Tornadoes often, though not always, form along weather fronts, where air masses of differing characteristics collide. The fronts that most commonly produce tornadoes are cold fronts and dry lines.
Can tornadoes form anywhere on the planet?
Yes but they are more likley to form in some places than others
Is it moist or dry when a tornado forms?
Generally the air is moist as tornadoes require thunderstorms to form.
Can a tornado happen without rain?
Yes, tornadoes can occur without accompanying rain. These are called "dry tornadoes" and can form in arid regions where there is little moisture in the air. Dry tornadoes can be especially dangerous as they may be harder to spot without the visual cue of rain.
