Tulsa, being located in the heartland of the continent, has a continental climate with well-marked seasons. Temperature variation throughout the year can be extreme, but Tulsa's weather is generally mild and pleasant. In the months of July and August (often into mid-September), temperatures over 40°C (100°F) are not unusual. The fall is cool and pleasant, but short. Though the winters are usually mild, the thermometer may dip below -20°C (0°F) at times, and on average, more than half the days in December, January and February are below freezing.

Wary of Tornados?

Tulsa is located in northeastern Oklahoma, an area that has some of the highest tornado activity in the United States. Most of the tornadoes do not do significant damage, as they either have narrow paths or dissipate quickly. However, during the spring and early summer, Tulsa is occasionally subject to sudden bouts of bad weather, including thunderstorms, high winds and a rare hailstorm. Much of the annual precipitation that the city gets (about 40in or 100cm) falls during these months. In the past, this has often led to extensive flooding (as Tulsa is located on a flat plain, water does not flow away from the city) after rainstorms. As a result, Tulsa has developed an excellent flood control system that received an award for flood plain management from FEMA in 2000.
