100 degrees in Dayton: How often does it get that hot?

There has been a lot of interest in a story we published this week about the area’s inclusion in an emerging “extreme heat belt” that is expected to produce days with a heat index above 125 degrees in 30 years.

That made some wonder how hot it gets in Dayton now.

We went to the National Oceanic and Atmospheric Association data to look. It turns out that, in the past 70 years, there have been 15 days with highs of at least 100 degrees.

Of those, almost half (7 of them) came during the summer of 1988.

Here’s a look at 100-degree days in Dayton since 1952.
