Average weather, temperature, rainfall, sunshine hours

The climate of Tulsa is
subtropical, with quite cold winters and very hot, muggy summers. The city is windy and exposed to clashes between air masses which cause
sudden changes in temperature, except in summer, when the heat prevails.
The city is located in Oklahoma, on the banks of the Arkansas River and 200 meters (650 feet) above sea level.
The
average temperature of the coldest month (January) is of 3.6 °C (38.5 °F), that of the warmest month (July) is of 28.5 °C (83.3 °F).
Precipitation amounts to 1,040 millimeters (41 inches) per year.
The
winter, from December to February, is quite cold, but above all it is characterized by the alternation of mild and cold periods. In fact, there are periods in which the temperature can exceed 20 °C (68 °F), and sometimes 25 °C (77 °F), even in the middle of winter, but also irruptions of cold air, with intense frosts and possible snowfalls.
On average, 22 cm (8.5 in) of
snow fall per year. The most abundant snowfall that occurred in one day was of 35 cm (13.8 in), in February 2011. The snowiest year was 1958, with 75 cm (29.6 in) of snow.
On average, there are 8 icing days (that is, on which the air temperature does not go above freezing), and this can happen from November through March.
On the coldest nights of the year, the temperature typically drops to around -15 °C (5 °F). The coldest record is -25 °C (-13 °F), set in February 2021.
The
summer, from June to mid-September, is very hot and sunny, with some thunderstorms.
Typically, the temperature reaches or exceeds 38 °C (100 °F) for 11 days a year. On the hottest days of the year, the temperature reaches 40/41 °C (104/106 °F).
The record heat is 45 °C (113 °F), set in August 2011.
In 2011, scorching heat lasted a long time, and the average maximum temperature was 40.1 °C (104.2 °F) in July and 38.8 °C (101.8 °F) in August.
In
spring and autumn, from March to May and from mid-September to the end of November, the collision between air masses can give rise to thunderstorms, sometimes accompanied by hail, gusts of wind and sudden changes of temperature. However, there are also stable and pleasant periods. Cold air outbreaks, with nighttime temperatures below freezing, are more likely in March and November, while heat waves are more likely in May and September.
Tulsa is subject to the phenomenon of
tornadoes, which generally develop in the period from April to June, and more rarely in autumn.
The city and metropolitan area are prone to flooding from the Arkansas River, as happened in May 2019.
Best Time
In Tulsa, there is no month in which it cannot be either hot or cold (or both), however, spring and autumn can be chosen, even if they are unstable seasons, and in particular, the months of April and October, with a preference for the latter because there is a lower risk of severe thunderstorms or tornadoes.
