As temperatures in North America gradually increase, spring blooms and pollen levels are high and so is crime, why is that? Does hot weather affect our tolerance to simple annoyances? Actually, yes it does.

Many studies have been done to understand the rise in crime during the months of summer. Studies in Chicago were conducted by using crime reports from the Cook County Police Department, and the data was shocking. The average number of assault and battery occurred during days with temperatures between 70 and 90 degrees showing a huge spike in crime opposed to days that are cooler. Could it be the city? The stress of being pent up in cramped apartments all winter? When winter comes  the amount of crime simmers down due to the fact that it’s colder than a fridge in the freezing winters of Northern America, who wants to freeze outside when you can be cozy inside?

You might be asking what about the cities where it’s always warm. A study done in Dallas determined the relationship between temperature to violent crimes. Their results showed a relationship was relevant to an increase in temperature became more moderate after 80°F and then a negative correlation showed up after 90°F.  The conclusion was that as it became hotter outside, people went inside to cooler environments and that crimes of opportunity decreased.  Again, our language matches decreasing temperature with calming down, because here people literally “cool off” or “chill out.”
