Keep reading to learn a little more about Oklahoma weather, including why Tulsa County is considered to have the worst weather, and even where you can find the best weather in Oklahoma. We are going to discuss every detail of Oklahoma weather right here in this article! 

What is the Weather Like in Oklahoma?

Oklahoma is a large state, in fact, it is the 20th largest state with almost 70,000 square miles of land. Within this vast area, the population is only 4 million people, which means that if you think Oklahoma might be the right place for you, you’ll have plenty of space! 

But it’s important to note that Oklahoma, while known for its expansive countryside, is also quite famous for its intense and unfortunate weather. 

The summers throughout Oklahoma are hot and muggy with more than 30 days a year reaching temperatures of over 100 degrees and between 65 and 115 days of temperatures above 90 degrees! 

While some report that the Oklahoma winters are considered mild, there are still cold fronts and even snowfall almost every year. Luckily, spring and fall are known to be quite beautiful, and across the state, you can enjoy all four seasons throughout the year. 

However, the average temperature is not what makes Oklahoma so well-known for intense weather. Oklahoma is quite prone to droughts, flash floods, wildfires, thunderstorms, ice storms, and tornadoes! 

Oklahoma lies in the center of an area known as Tornado Valley and averages 62 tornadoes every year.

That’s a lot of weather for one state, but within the state itself, there are certain areas that are more susceptible to these natural occurrences, so let’s dig a little deeper into where in Oklahoma has the worst of the bad weather.

These events included hail storms (19 per year), flash floods (11 per year), and thunderstorm winds (21 per year), as well as the many twisters that came through: there were 10 tornados in Tulsa County in May 2020!
