This sizzling summer matched the summer of 1980 for number of days in the 100s on Wednesday, while handily setting a record high for the date.
The 107 high toppled the previous mark of 104, posted in 2000.
It also raised the number of 100-degree days to 46, equal to summer 1980 and second only to the 50 of summer 1936.
"This is one of the hottest summers we've had" in Wichita, National Weather Service meteorologist Jim Caruso said. "There's no way around that."

The heat prompted Wichita school officials to warn principals and coaches about the dangers of outdoor practices and recess.
Darren Muci, Wichita's division director of operations, issued an e-mail Wednesday morning urging principals and coaches to "take all necessary and prudent precautions when considering outside activities for our students."
Wichita students started school last week, and fall sports such as football and cross country are practicing regularly.
Individual school principals still decide whether students go outside for recess, said district spokeswoman Susan Arensman.
A check with area schools showed few allowed children outside for recess.
The heat isn't ready to let up, either.
Forecasts call for another 100-degree day Friday, and Saturday could come close again.
"This," said Chris Jakub, a meteorologist with the weather service, "has been a brutal summer."
