The highest heat index on record occurred Tuesday in San Antonio🥵

No doubt about it -- the heat and humidity have been in full force this June!

Afternoon dewpoints in the mid-upper 70s occurred in San Antonio Thursday (6/15), Friday (6/16), and Tuesday (6/20) making feels-like temperatures soar well into the triple digits across the majority of South Central Texas.

Here in San Antonio, the peak heat index value managed to climb to 113 degrees Thursday (6/15), which made for a record. Thursday’s record lasted for a measly 24 hours when the very next day, Friday (6/16), the record was broken again with a heat index of 115 degrees.

To make things even more toasty, the record was yet again broken on Tuesday (6/20)! A peak heat index of 116 degrees has now been calculated at San Antonio International Airport, snagging the top spot for the hottest heat index value on record.
