On Sunday, the inevitable came when the mercury hit triple digits for the first time in 2012 in San Antonio.
And it kept firefighters busier than usual with 11 heat-related calls.
"One of our biggest problems is that we're making EMS runs where people have not drank enough water and they're dehydrated and that makes them feel ill so that's one of the basic things they can do," said Deb Foster, with the San Antonio fire department, adding that this year the department has made 68 calls compared with 66 in the same time frame in 2011.
The heat index on Sunday and Monday hovered around 105 degrees. Dangerous conditions that can sometimes make heat issues tough to detect.
"They might just think it's something they ate but it's like nausea, if they have headaches and they feel weak or dizzy, it could very well be the heat so get to a place that's cooler, cool yourself down," added Foster"
Officials have already begun weekly Monday morning meetings to address heat issues.
The city has yet to officially designate cooling centers across the city which consist of public libraries, senior centers and community centers.
The Bazan branch library on Commerce had a good crowd with a few people taking advantage of the free air conditioning inside.
"I've got medical problems like high blood pressure and diabetes and it helps me to stay out of the heat," said Franklin Martinez. "To get out of the heat I come over here or go to the River Center mall or this library or any other library."
Public library hours vary by day and location. You can check their site for times.
The city has also kicked off its annual Project Cool, which provides box fans to residents in need.
Anyone can drop off fans at any San Antonio fire department. If you are in need of a fan, you can request one at 211.
